Carbon steel is one of main materials in steel casting industry. According to the carbon contents, carbon steels are classified as three types:
Low-carbon steels(< 0.20% C): A range of tensile properties are provided by heat treatment, and may be hardened to provide high surface hardness with abrasion resistance and good core ductility.
Medium-carbon steels(0.20 to 0.50% C): This grade makes it more durable, pliable and stronger. A range of tensile strengths are possible, with good ductility and impact resistance, easy to for secondary machining in a softened state.
High-carbon steels(> 0.50% C): High strength, good shape memory, is a particularly good option for spring manufacturers. This alloy steel for high strength applications is subject to wear and abrasion and is also suitable for heavy duty applications.
