42CrMo high tensile steel
42CrMo high strength steel is an ultra-high strength steel with high strength and toughness, good NMenability, no obvious temper brittleness, high fatigue limit and multiple impact resistance after quenching and tempering, and low temperature impact toughness. good.
42CrMo high strength steel plate is generally used to manufacture important structural parts that work under high loads: such as shafts, gears, connecting rods; transmission gears, supercharger gears, engine cylinders and other industries.
