1. Introduction to 35CrMnSiA materials

      35CrMnSiA is a low alloy ultra-high strength steel. It has good comprehensive mechanical properties after heat treatment, high strength, sufficient toughness, good hardenability, welding (preheating before welding), and processing and forming properties, but has low corrosion resistance and oxidation resistance. It is generally used after low temperature backtempering, isothermal quenching or after tempering.

IV. 35CrMnSiA application field

      35CrMnSiA is used to manufacture medium-speed, heavy-duty, high-strength, and high-strength components and high-strength components.

      Manufacture various important parts with high load and high speed, such as gears, shafts, clutches, sprockets, grinding wheel shafts, sleeves, bolts, nuts, etc.

      Manufacture parts with wear-resistant and low working temperatures, variable load welding components, such as blades, valve plates and non-corrosive pipeline pipes of high-pressure blowers.
