GB/T 3077 35CrMnSiA alloy steel plate is a low-alloy ultra-high-strength steel, GB/T 3077 35CrMnSiA alloy steel plate has a good overall mechanical properties after heat treatment, high strength, sufficient toughness, hardenability, weldability (preheating before welding), processing formability are good, but the corrosion resistance and Low oxidation resistance, GB/T 3077 35CrMnSiA alloy steel plate generally used after low temperature tempering or isothermal quenching.
GB/T 3077 35CrMnSiA alloy steel plate is used to manufacture medium-speed, heavy-duty, high-strength, high-toughness parts and high-strength components. It is mainly used for manufacturing high-load, high-speed various important parts, such as gears, shafts, clutches, sprockets, grinding wheel shafts, bushings, bolts, nuts, etc. GB/T 3077 35CrMnSiA alloy steel plate is also used to make parts that are wear-resistant, have low working temperatures, and change loads. Welded components, such as blades, valve plates, and non-corrosive pipe tubes of high-pressure blowers
