1.6580 steel
Products Description
1.6580 steel tempering refers to the process of rapid cooling after heating to high temperature, and then heating treatment at medium temperature. The hardness, strength and toughness of 30CrNiMo8 were improved by tempering treatment. By tempering treatment, 30CrNiMo8 can achieve tensile strength of up to 1000MPa.
In addition, 1.6580 steel also has good weldability. Different welding methods can be used, such as arc welding and gas shielded welding.
In short, 1.6580 steel is a high-quality tempered steel with excellent strength, toughness, fatigue resistance and wear resistance. It is suitable for manufacturing parts with high strength requirements and has good weldability. In related industries, it is widely used in a variety of important mechanical parts.
