Product Introduction

42CrMo4 Forging

42CrMo4 is a commonly used structural steel material with good mechanical properties and heat treatment properties. It is widely used in the manufacture of tools and mechanical parts, such as bearings, gears, pins, etc. The following are the detailed performance parameters of the 42CrMo4.

1. Chemical composition: The chemical composition of 42CrMo4 includes carbon (C), silicon (Si), manganese (Mn), phosphorus (P), sulfur (S), chromium (Cr), molybdenum (Mo) and iron (Fe). Among them, the carbon content is 0.38-0.45%, the silicon content is 0.4%, the manganese content is 0.6-0.9%, the phosphorus and sulfur content are controlled below 0.035%, the chromium content is 0.9-1.2%, the molybdenum content is 0.15-0.3%, and the iron is the surplus.

2. Mechanical properties: 42CrMo4 has high strength and wear resistance. Its yield strength is 900-1100 MPa, tensile strength is 1100-1300 MPa, elongation is 10-15%, and section shrinkage is 45-50%. These mechanical properties make 42CrMo4 suitable for work environments with high strength and large deformation.

3. Heat treatment performance: 42CrMo4 has good heat treatment performance, which can be improved by heat treatment processes such as normalizing, quenching and tempering. Normalizing can increase its hardness and strength, quenching can improve its wear resistance and toughness, tempering can reduce its brittleness and strength, and increase its machinability. According to the specific application requirements, different heat treatment schemes can be selected.

4. Scope of use: Because 42CrMo4 has excellent mechanical properties and heat treatment properties, it is widely used in the manufacturing field. For example, in tool manufacturing, it is suitable for the manufacture of high-strength components such as bearings, gears and pins; In mechanical manufacturing, it can be used to manufacture structural parts that bear high loads and large deformation.
