42CrMo4 1.7225 Bar

42CrMo4 is an alloy steel with high strength and wear resistance, commonly used in the manufacture of machine parts, gears, bearings and automotive parts.

The chemical composition of the material is: carbon (C) 0.38-0.45%, silicon (Si) 0.15-0.35%, manganese (Mn) 0.50-0.80%, phosphorus (P) up to 0.025%, sulfur (S) up to 0.035%, chromium (Cr) 0.90-1.20%, molybdenum (Mo) 0.15-0.30%.

The strength and toughness of the material are high, and its physical properties can be adjusted by heat treatment. It is usually modified by quenching and tempering to improve its mechanical properties and durability. Quenching hardens the material and changes its strength, but it also makes it brittle, so tempering will continue to work on the material to give it moderate strength and improve toughness. In addition, 42CrMo4 can also be normalized and post-quench treatment to change its physical properties

42CrMo4 has good wear resistance and toughness and is a common industrial material. It is commonly used in the manufacture of high-strength machine parts, transmission components for heavy vehicles and automotive rocker arms. Due to its high machinability and heat treatment properties compared to other high-strength materials, it is often used to manufacture mechanical parts that require a high degree of precision and reliability.
