SCr440 Chrome Steel
The chemical composition of SCR440 steel mainly includes carbon (C), silicon (Si), manganese (Mn), sulfur (S), phosphorus (P), chromium (Cr) and molybdenum (Mo). Among them, the carbon (C) content is 0.38-0.43%, silicon (Si) content is 0.15-0.35%, manganese (Mn) content is 0.60-0.90%, sulfur (S) content is not more than 0.030%, phosphorus (P) content is not more than 0.040%, chromium (Cr) content is 0.90-1.20%, and molybdenum (Mo) content is 0.15-0.25%.
Description
Product Application
SCR440 steel is a high-quality alloy structural steel. Here is a detailed introduction to SCR440 steel:
Standard:
The standards for SCR440 steel mainly include JIS G4104 and KS D3752.
Chemical composition:
The chemical composition of SCR440 steel mainly includes carbon (C), silicon (Si), manganese (Mn), sulfur (S), phosphorus (P), chromium (Cr) and molybdenum (Mo). Among them, the carbon (C) content is 0.38-0.43%, silicon (Si) content is 0.15-0.35%, manganese (Mn) content is 0.60-0.90%, sulfur (S) content is not more than 0.030%, phosphorus (P) content is not more than 0.040%, chromium (Cr) content is 0.90-1.20%, and molybdenum (Mo) content is 0.15-0.25%.
Tensile strength, yield strength and elongation at break:
The tensile strength of SCR440 steel is 980 MPa, the yield strength is 835 MPa, and the elongation at break is 15%.
Application:
SCR440 steel is widely used in mechanical manufacturing, automobile manufacturing, aerospace and other fields, and is commonly used in the manufacture of transmission shafts, engine crankshafts, connecting rods, gears, propeller shafts and turbine shafts and other parts.
Status:
SCR440 steel can obtain different mechanical properties and microstructures through heat treatment methods such as normalizing, quenching and tempering.
Advantages:
SCR440 steel has high tensile and yield strength, as well as good machinability and weldability. It also has good heat resistance and fatigue strength, and has a long service life.
Disadvantages:
The hardness of SCR440 steel is relatively high, which may cause difficulties in processing. In addition, the impact toughness of SCR440 steel is relatively low.
Most common forms:
The most common forms of SCR440 steel include bars, plates and steel pipes.
Comparison of international grades:
SCR440 steel corresponds to AISI 4140, DIN 1.7225 and 42CrMo4 steel internationally.
Conclusion:
SCR440 steel is a high-quality alloy structural steel with high tensile and yield strength, good machinability and weldability. It is widely used in mechanical manufacturing, automobile manufacturing, aerospace and other fields, and is commonly used in the manufacture of various parts. The hardness of SCR440 steel is relatively high, which may cause difficulties in processing, and its impact toughness is relatively low. The most common forms of SCR440 steel include bars, plates and steel pipes. Internationally, SCR440 steel corresponds to AISI 4140, DIN 1.7225 and 42CrMo4 steel.
