gb 42crmo steel is an ultra-high strength steel with high strength and toughness, good hardenability, no obvious temper brittleness, small deformation during quenching, high fatigue limit and multiple impact resistance after quenching and tempering, good low-temperature impact toughness, high variable strength and lasting strength at high temperature.

gb 42crmo steel is used to manufacture forgings that require higher strength and larger quenched and tempered sections than 35crmo steel, such as large gears for locomotive traction, supercharger transmission gears, pressure vessel gears, rear axles, connecting rods and spring clips with extremely high loads.

it can also be used for oil deep well drill pipe joints and salvage tools below 2000m, and can be used for bending machine molds, etc.
