Steel is an ultra-high-strength steel with high strength and toughness, good hardenability, no obvious temper brittleness, small deformation during quenching, and high fatigue limit and multiple resistance after quenching and tempering. Impact ability, good low-temperature impact toughness, high creep strength and durable strength at high temperatures. This steel is usually tempered and then surface quenched as a heat treatment solution.
High strength, hardenability, good toughness
Small deformation during quenching, 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 3 steel, such as large gears for locomotive traction, supercharger transmission gears, pressure vessel gears, rear axles, and connections with extremely high loads. Rods and spring clips 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.
