EN 1.7225 (42CrMo4) Chromium Molybdenum Steel

42crmo4 is an industrial material. 42CrMo4 is used to manufacture forgings that require higher strength and larger tuning cross-section than 35CrMo steel, such as large gears for locomotive traction, supercharger transmission gears, rear shafts, connecting rods and spring clips with great loads, 42CrMo4 can also be used for drilling pipe joints and fishing tools in deep oil Wells below 2000m.

Chemical composition

42CrMo4 steel plate is a high-strength alloy steel plate, its chemical composition includes carbon, silicon, manganese, phosphorus, sulfur, chromium and molybdenum and other elements. Among them, the carbon content is between 0.38-0.45%, the silicon content is between 0.15-0.35%, the manganese content is between 0.60-0.90%, the phosphorus and sulfur content are not more than 0.035%, the chromium content is between 0.90-1.20%, and the molybdenum content is between 0.15-0.30%. This steel plate has good mechanical properties and heat treatment properties, and can still maintain high strength and toughness at high temperatures. It is widely used in machinery manufacturing, aerospace, automotive industry and other fields, often used in the manufacture of high-strength bolts, bearings, gears, hydraulic cylinders and other parts. Chemical composition is one of the important factors that determine the performance of steel plate, 42CrMo4 steel plate chemical composition is excellent, so that it is widely used in industrial manufacturing

Heat treatment process

42CrMo4 steel plate is a kind of high-strength alloy steel plate, which is widely used in machinery manufacturing, aerospace, automobile manufacturing and other fields. In order to improve the properties of steel plates, heat treatment is required. The heat treatment process includes three steps: heating, holding and cooling. First, the steel plate is heated to the appropriate temperature so that it reaches the corresponding crystal structure, usually 800-1100 ° C. Then, a constant temperature is maintained during the holding time to homogenize the crystal structure of the steel plate. Finally, the crystal structure of the steel plate is fixed by different cooling methods, such as water quenching, oil quenching or air cooling, so as to obtain the required performance. In the heat treatment process, temperature, holding time and cooling method are very important factors. The correct heat treatment process can improve the hardness, strength and toughness of the steel plate, while reducing its brittleness and deformation rate. In short, the heat treatment process of 42CrMo4 steel plate is an important process that can improve the performance and service life of the steel plate. The heat treatment process is an essential step for applications in mechanical manufacturing, aerospace, automotive manufacturing and other fields.
