Carbon steel casting
Carbon Steel Casting
Carbon steel casting is a manufacturing process that produces components by pouring molten carbon steel into molds. Carbon steel is an alloy of iron and carbon, with varying carbon content (typically 0.1% to 2.1%) that influences its mechanical properties. Known for its excellent strength, toughness, and wear resistance, carbon steel is widely used in applications requiring durability and reliability.
We specialize in producing high-quality carbon steel castings for industrial and engineering applications. With decades of experience and advanced foundry facilities, we supply durable and cost-effective cast components for machinery, mining, construction, oil & gas, and power generation industries. Our carbon steel castings combine high strength with versatility, making them an ideal solution for critical parts under demanding conditions.
