Steel is an ultra-high-strength steel with high strength, hardenability, good toughness, small deformation during quenching, and high creep strength and durable strength at high temperatures. It is used to manufacture forgings that require higher strength and larger quenched and tempered cross-sections than steel, such as large gears for locomotive traction, supercharger transmission gears, pressure vessel gears, rear axles, connecting rods and spring clips that are subject to extremely high loads. It can also be used for the following oil deep well drill pipe joints and fishing tools, and can be used for bending machine molds, etc.
