Supply 30CrMnTi Gear Steel/BAOSTEEL
Features and Scope: the strength of steel than 20CrMnTi, hardenability high, but slightly lower impact toughness. Mainly used for carburizing steel, carburizing temperature directly after quenching, the higher flexural strength, good wear resistance. Can be quenched or quenched and after tempering the use of secondary machining. Tractor industry in the cross section for the manufacture of heavy duty carburized parts larger and larger force gear, gear shaft, worm and so on.
