The technical properties of 35CrMo4 steel include a high tensile strength, good elongation, and excellent fatigue strength. These properties make it suitable for applications in the automotive and aerospace industries.
The chemical composition of 35CrMo4 steel typically includes 0.32-0.40% carbon, 0.40-0.70% silicon, 0.60-0.90% manganese, 0.90-1.20% chromium, and 0.15-0.25% molybdenum. This composition contributes to the steel’s high strength and toughness.
The heat treatment process for 35CrMo4 steel typically involves quenching and tempering. Quenching is the rapid cooling of the steel from a high temperature to room temperature in order to increase its hardness, while tempering is the reheating of the quenched steel to a lower temperature to reduce brittleness and improve toughness.
By carefully controlling the heat treatment process, engineers can tailor the mechanical properties of 35CrMo4 steel to meet the specific requirements of different applications. This allows for the production of components with the desired combination of strength, toughness, and fatigue resistance.
