30CrMnSiA alloy steel characteristics and applications:
High-strength quenched and tempered structural steel, boasting high strength and toughness, good quenching penetration, moderate cold deformation plasticity, excellent machinability, with a tendency towards temper brittleness, poor transverse impact toughness, good welding properties; however, when thickness exceeds 3mm, preheat to 150℃ before welding and subsequent heat treatment. Generally used after quenching and tempering, it is commonly employed in the manufacture of critical components subjected to high loads and high speeds, such as gears, shafts, clutches, sprockets, abrasive wheel shafts, bushings, bolts, nuts, etc. It is also used for making wear-resistant parts with low operating temperatures and variable load welding structures, such as the blades of high-pressure blowers, valve plates, and pipes for non-corrosive pipelines.
