Product Introduction

42CrMo4 steel round is a kind of imported steel, which belongs to tempered and quenched steel, with high strength and toughness. The steel is mainly used in the manufacture of mechanical parts, especially in the field of automobile manufacturing and construction machinery.

The chemical composition of 42CrMo4 steel includes:

Carbon (C) content is 0.38-0.45%,

silicon (Si) content is 0.40%,

manganese (Mn) content is 0.60-0.90%,

phosphorus (P) content is not more than 0.025%,

sulfur (S) content is not more than 0.035%,

chromium (Cr) content is 0.90-1.20%,

Molybdenum (Mo) content is 0.15-0.30%.

The content of these elements makes 42CrMo4 have good heat resistance and fatigue resistance. 42CrMo4 steel is treated by tempering and quenching process to obtain high hardness and good toughness. Quenching is the rapid cooling of the material after heating to high temperatures to change the crystal structure and improve the performance of the steel. Tempering quenching can significantly improve the tensile strength and hardness of 42CrMo4 steel, while maintaining high toughness and impact resistance. Imported 42CrMo4 steel has a wide range of applications in the manufacture of mechanical parts such as structural parts, bearings and gears. Due to its high strength and good hardness, it can be used to produce parts that withstand large loads and shocks, such as drive shafts, crankshafts and gear systems for automobiles. In addition, 42CrMo4 steel can also be used to manufacture key components of construction machinery, such as hydraulic cylinders, frames and track chains for excavators. In short, the imported 42CrMo4 steel is a tempered and quenched steel with high strength, good toughness and fatigue resistance. It is widely used in the field of mechanical manufacturing, especially in the field of automobile manufacturing and construction machinery, and is often used to manufacture various important parts.
