Cast carbon steel is the kind of cast steel with carbon as the main alloying element and a small amount of other elements. Cast carbon steel can be divided into cast low carbon steel, cast medium carbon steel and cast high carbon steel. The carbon content of cast low carbon steel is less than 0.25%, the carbon content of cast carbon steel is between 0.25% and 0.60%, and the carbon content of cast high carbon steel is between 0.6% and 3.0%. Performance Characteristics of Steel Castings:
- • Poor fluidity and volume shrinkage and linear shrinkage are relatively large
- • Comprehensive mechanical properties are relatively high. Compressive strength and tensile strength are equal
- • Poor shock absorption and high notch sensitivity
- • Low carbon steel castings have relatively good weldability.
