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.
Advantages of Sand Casting
● Almost any ferrous and non-ferrous metals can be casted by sand casting
● Parts caan vary greatly in size, weight and shape. Weight can be from ounces to hundreds of tons
● Cost of tools is low comparing to other process
● Small quantity or large quantity
● Relative low cost for high volume parts
