Steel grades for manufacturing various machine parts, such as shafts, gears, fasteners, bearings and high-strength structures, are widely used in automobiles, tractors, machine tools, engineering machinery, and power station equipment.
Steels with a tensile strength greater than 1400 MPa and a yield strength greater than 1200 MPa at room temperature are called ultra-high strength steels, which have good plastic toughness, excellent fatigue properties, fracture toughness and stress corrosion resistance.
It is widely used in petroleum exploration drill collars and chemical equipment. The main material forms are plates, forgings, steel pipes, welding materials and bars. Related grades are N1310 non-magnetic steel, 4145H, 4340, etc.
The steel is used in robot parts, transmission parts, especially the slide rails that highlight the advantages, and the slide block steel, which has strong wear resistance,
Application of high-speed rail, automobile industry connections, fasteners, fasteners, stamping dies, springs, bearings, transmission shafts, crankshafts, cams and gears and other components;
