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.
