35CrMnSiA alloy application ranges:
35CrMnSiA steel is used to manufacture heavy-duty, high-strength, high-toughness parts and high-strength components. It can also be used to manufacture various important parts with high load and high speed, such as gears, shafts, clutches, sprockets, grinding wheel shafts, bushings, bolts, nuts, etc. 35CrMnSiA is also used to manufacture parts with wear resistance and low working temperature, variable load welding components, such as high-pressure blower blades, valve plates and non-corrosive pipes.
