35CrMo steel is a type of alloy steel that has a high hardness and strength. It contains elements such as chromium and molybdenum, which contribute to its remarkable performance in high-temperature and high-pressure applications. The steel is used as a material for high-stress machine parts, such as gears and shafts, and is also widely used in the petroleum industry for drill pipe, drill collar, and heavy-duty components.
The chemical composition of 35CrMo steel contains 0.32-0.40% carbon, 0.17-0.37% silicon, 0.40-0.70% manganese, 0.80-1.10% chromium, 0.15-0.25% molybdenum, and less than 0.035% phosphorus and sulfur. This composition provides it with excellent mechanical properties, such as high strength, toughness, and wear resistance.
35CrMo steel has a hardness of approximately 250-280 HBW (Rockwell hardness), which makes it ideal for high-pressure and high-temperature applications. It can be heat-treated to achieve different levels of hardness, such as annealing, normalizing, and tempering.
Overall, 35CrMo steel is a versatile type of alloy steel that finds its application in many industries, such as aerospace, automotive, construction, and petroleum industries. Its excellent mechanical properties make it an ideal choice for manufacturing machine parts subjected to high stress and impact loads.
