Detail information of 30CrMnSi alloy structural steel

Application of 30CrMnSi alloy structural steel:
30CrMnSi steel is used to manufacture a variety of high-load, high-speed important parts such as gears, shafts, clutches, sprockets, axles, bushings, bolts, nuts, etc. 30CrMnSi alloy structural steel is also used to manufacture parts with low wear resistance, low operating temperature, variable load welded parts, such as high pressure blower blades, valve plates, etc.

The 30CrMnSi alloy structural steel is the alloy structural steel brand stipulated by the Chinese national standard. Unified digital code: A24302.

Main characteristics of 30CrMnSi alloy structural steel:
The 30CrMnSi alloy structural steel is a high strength quenched and tempered steel. It has high strength and toughness, high hardenability, moderate plastic deformation and good processability. It has temper brittleness and lateral impact toughness. The welding performance is good, but when the thickness is more than 3mm, the 30CrMnSi steel should be preheated to 150°C, heat treated after welding, and used after quenching and tempering.

Pre: ASTM A572 grade 65 low alloy steel has a much longer service life than carbon steel.
