Impact of Global Energy Transition and Renewable Energy Expansion on the Iron and Steel Casting Market

The iron and steel castings market is gaining significant long-term growth potential with the transition to renewable energy throughout the world. Demand for high-performance cast components in wind turbines, solar tracking systems and hydroelectric structures is being bolstered by increased investments in wind, solar, and hydroelectric technologies.

The global renewable energy market is growing at an impressive rate and is expected to see investments surpass USD 2.8 trillion by 2035, which will drive up the demand for iron and steel castings by approximately 4% annually. The pattern is driving foundries to shift from the cyclical car industry to the less volatile renewable energy infrastructure industry, thereby spreading their risk and making new opportunities.

Significant Growth Factors

Rising Automotive Industry Demand Driven by Vehicle Production Recovery and Electric Vehicle Platform Expansion:

The automotive industry is the largest application area for iron and steel castings with a share of about 32% of the global casting volume for 2025 and continues to be the most important application region for iron and steel castings. Automotive production bounced back strongly from below 2020–2021 pandemic levels, and the global automotive OEMs’ capital expenditure spent on automotive vehicle programs, manufacturing capacity growth, and development of EV platforms exceeded USD 90 billion annually, which equates to the automotive industry casting procurement for an average of 40–50 kg of castings per vehicle.

While the shift to more electric vehicles will result in a reduced demand for traditional cast iron engine blocks, it will also partially offset this trend through increased demand for casting for electric motor housings, battery enclosures, battery cooling thermal management systems, and high-strength structural components supporting the increased mass of lithium-ion battery packs.

The automotive industry’s light-weighting initiatives, which come as a result of tight CO₂ emission regulation in Europe (where manufacturers will have to average their fleet below 50 to 55 grams CO₂/km by 2030), as well as fuel efficiency regulations in other markets, drive the need for high-strength, lightweight ductile iron and special steel castings, which offer high strength to low weight and have premium prices, resulting in higher per-unit revenue realization even if volume is moderate in combustion engine castings.

Infrastructure and Construction Sector Expansion Across Emerging Economies and Post-Pandemic Recovery in Developed Markets:

Iron and steel castings are used in a wide variety of industries and applications, including the construction and infrastructure industry, where casting-intensive applications are found in architectural hardware, structural fasteners, drainage and plumbing systems, sections of electrical infrastructure, and large structural components for bridges, tunnels, and industrial facilities.

Based on the demand for casting intensive materials such as water supply systems, railway infrastructure, and power distribution systems, the demand for the casting process is expected to be high with cumulative investment in infrastructure projected to reach USD 4 trillion across emerging and developed economies, with the Asia Pacific region being the primary driver of infrastructure investment, accounting for USD 1.5 trillion of the total spending through 2025, due to China’s ongoing urbanization and India’s ambitious infrastructure development plans launched under the National Infrastructure Pipeline program with USD 1.5 trillion of infrastructure investment expected through 2025.

Global construction equipment production, which is closely tied to iron and steel castings for its chassis, engines, hydraulic systems, and structural parts, grew by almost 3.4% in 2024 and is forecast to grow at a similar rate of around 3.4% through 2035, according to the International Construction and Equipment Council. Overall market growth is being driven by the casting volume growth that is needed for emerging market growth acceleration, whereas developed market infrastructure recovery is sustaining and maintaining casting requirements for water infrastructure renewal, road and rail system upgrades, and bridge reconstruction at stable baseline levels, in addition to recently announced USAID $1.2 trillion infrastructure spending under the Infrastructure Investment and Jobs Act of 2021.

What are the major advances changing the iron and steel casting market today?

Additive Manufacturing (3D Printing) Integration for Mold Fabrication and Complex Prototype Development Reducing Time-to-Market and Tooling Costs:

Perhaps the biggest technical breakthrough that is poised to change the iron and steel casting manufacturing process occurs with the widespread use of 3D printing to directly create molds, cores and casting patterns, which removes the longest lead-time constraint in the traditional casting process and can reduce weeks of machining and assembly to just hours for the creation of conventional cast tooling.

Meanwhile, foundries are more and more using 3D printing to produce complex geometry that would be difficult if not impossible to produce using traditional mold-making methods and to shrink mold-making times, save on materials and increase the speed of getting prototypes ready to shorten product development cycles. Nippon Steel is demonstrating this new step forward with its collaboration with MADIT to create 3D-printed impellers in which it achieved a 55% weight saving and a 40% cost saving over the traditional casting design, showing that 3D-printed components can offer performance and cost benefits over castings in specific applications.

In January of 2025, GF Casting Solutions announced in its press release that by 2026, the company will introduce a global network of mega-casting machines in China, Europe and the United States, offering tailored, cutting-edge casting solutions based on its advanced product and process development knowledge and test equipment. However, there are still issues that prevent 3D printing from being more widely adopted at an industrial level for high volume commodity casting, such as material costs, the size of the build platforms, which limit the casting size of the parts, and slower printing speeds, which limit production volumes.

But the technology is becoming increasingly the go-to method for prototype development, short-run specialty casting and more intricate geometries where the premium cost and time investment can be justified by the cost savings. In this way, a two-tiered manufacturing market is emerging, with 3D printing mold production being the preferred option for low-to-medium volume specialty casting and conventional sand and permanent mold casting being the preferred option for high-volume, standard components.

Artificial Intelligence and Machine Learning Integration for Predictive Maintenance, Process Optimization, and Quality Assurance in Casting Foundries:

The other major development that is helping reshape the competitive landscape of the iron and steel casting market is the extensive use of artificial intelligence, machine learning and digital twin technologies to fine-tune the process parameters used to create castings and to predict when equipment is likely to fail and when production is likely to become non-conforming due to that failure, thereby enabling the setting of zero-defect production objectives that could not be met by manually controlling the process.

At every stage of production, ArcelorMittal, the world’s largest steelmaker, has implemented a “Smart Steel” strategy based on a digital transformation, such as the use of digital twin technology to optimize blast furnace operations, including automated forecasts of potential defects in the hot rolling processes; and AI-driven logistics systems, which optimize deliveries on the spot and track them in real time.

Producing the same amount of steel at Nucor Corporation’s Memphis, Tennessee plant requires about 80 percent fewer staff hours thanks to AI-powered production scheduling, and automation at various plants is helping to make lasting progress in safety performance and cost structure by predictively identifying developing faults in casting equipment, allowing for controlled maintenance during planned production downtime windows, and eliminating the need for emergency production shutdowns that can cost hundreds of thousands of dollars per hour in lost productivity.

POSCO has set up transparent targets to create zero-defect production lines by 2025, investing in smart inspection systems with AI vision systems that detect defects at a microscopic level on the steel surface; energy management algorithms that minimize energy consumption in plant facilities; and data-driven customization systems that suggest the optimum steel grades for specific customer applications.

The business case for investing in AI and automation is clear: an unplanned downtime episode in a continuous casting operation can cost more than USD 1 million an hour, whereas an AI model that can detect developing equipment faults 48 hours ahead of time will allow time that can be scheduled during planned downtime to maintain the production process without losing asset utilization.

Category Wise Insights

By Material Type

Why Do Iron Castings Dominate the Market Volume Despite Steel Castings Commanding Higher Per-Unit Value?

In 2025, the volume share of iron castings was around 78.23%, which indicated that iron castings are widely used in the automotive, machinery, construction and industrial equipment manufacturing industries, and because of their versatility and price competitiveness for commodity manufacturing, they have dominated the market. A major advantage of gray iron is that it is the most readily machined of all irons, requiring no special secondary operations, which results in significantly lower secondary processing costs.

In addition, its vibration-damping properties make it the best choice for machinery housings and engine blocks and its thermal conductivity characteristics help dissipate heat in engine and power generation applications. This ductile iron, which was developed in the 1950s and was a significant technical improvement over gray iron in fracture resistance and tensile strength, has gradually replaced gray iron in the manufacture of components that carry load, such as automotive suspension parts, transmission cases, and machinery parts that are subjected to impact or cyclic loading and where the higher ductility is needed to prevent catastrophic brittle fracture.

Although accounting for around 21.77% of total castings volume in 2025, the higher per unit value for steel castings is attributed to their ability to withstand higher tensile and superior fatigue characteristics compared to other materials, which makes them suitable for power generation, renewables, aerospace and other specialized industrial machinery applications in extreme temperatures and high pressures. The material segment with the highest volume growth is the steel casting segment, which is expected to grow by 5.68% CAGR from 2015 to 2020, owing to the growing demand for renewable energy infrastructure, which needs components with high strength and thermal properties, such as wind turbine components, hydroelectric turbine casings, and thermal power generation equipment, which are only provided by steel castings.

By Casting Process

Why Does Sand Casting Maintain Dominant Volume Share Despite Investment Casting’s Superior Quality Characteristics?

In 2025, the top revenue share was made up of sand casting (around 63.7%), as it is the most basic casting method and is used in large-scale casting production in all material categories; it can be produced with lower cost, large casting components and complex geometric components can be produced by sand casting, and the sand casting process is well developed, and the supply of sand casting materials is also well developed, with a global supply chain infrastructure for material sourcing, reclamation, and environmental remediation.

The economic justification of sand casting is that it is cheaper than the permanent tooling used for die casting or investment casting. Sand molds are made at about USD 15–100 per mold, while die tooling for die casting can cost over USD 100,000 for a single cavity and the production volume of die castings must be more than 100,000 units to be economical.

The machinability and grain structure of sand-cast parts are not as good as investment-cast parts, and in many cases, the secondary machining cost for dimensional accuracy and surface finish will be higher than the total cost of performing investment casting approaches.

The investment casting market is growing the fastest at around 7.2% CAGR between 2026 and 2035, as the market is expected to see the highest demand for precision components in aerospace, medical devices, high-performance machinery, and special applications for automotive, where the superior surface finish, dimensional precision and casting quality of investment castings eliminate secondary machining, justify the higher per-unit investment casting cost, and enable the production of complex geometries not possible using sand casting.

The investment casting market for aerospace and defense applications is especially strong, with unit prices of USD 50,000-500,000 and production runs as low as a single unit or low double-digit numbers being economically viable, given the high quality requirements and performance specifications that mean that secondary machining is not possible.

By Application

Why Does Automotive Remain the Largest Application Despite Energy and Renewable Sector’s Rapid Growth?

In 2025, automotive components accounted for the highest application volume share of around 32%, highlighting the role of castings within all vehicle powertrain architectures, including legacy internal combustion engines and rising electric vehicle platforms, which demand casting-intensive parts in battery housings, thermal management systems, motor supports, and chassis. Across the automotive industry, the casting requirements for an engine block, transmission housing, brake, suspension and chassis frame are roughly 40-50 kg per vehicle, or more than 3 million metric tons (MT) of automotive casting volume per year, industry-wide.

Electric vehicle platform transition does not remove the demand for castings, but rather shifts them to electric motor stator housings, battery thermal management components, and electrical chassis components that are similar or thicker in material thickness and structural integrity to what is found in an ICE-powered vehicle.

Although this segment remains a significant volume contributor in 2025, it is the fastest-growing application segment, driven by the expected continued annual growth in global renewable energy capacity installation in the range of 15.1% and the casting-intensive nature of renewable energy infrastructure, where a single large offshore wind turbine (12 MW capacity) requires around 2,500 metric tons of steel castings for nacelle structures, hub adapters, bearing housings, and drivetrain components.

By End Use

Why Does Industrial Manufacturing Lead While Energy and Automotive Segments Provide Incremental Growth?

The castings market revenue for industrial manufacturing accounted for around 41% of the total market revenue in 2025, owing to the essential use of castings in manufacturing pumps, compressors, motors, gearboxes, valve bodies, and industrial machinery in all manufacturing industries. Multi-decade service life requirements for the industrial equipment market have resulted in an increased demand for quality castings with long service lives in various applications such as mining, oil & gas, food processing, and textile equipment, where a casting failure could mean millions of dollars in lost revenues per day and where premium specifications of materials and manufacturing processes are required.

The automotive OEM and Tier-1 supplier end-use is a major contributor to the market, accounting for around 30% of market revenue, whereas the energy and utilities segment (power generation, renewable energy, and water utilities) accounts for around 18% of total market revenue and is growing at the fastest rate at around 7.1% CAGR, owing to growth in renewable energy infrastructure and the structural shift across the global electric power industry towards wind and solar power.
