30crmnti Introduction
● Features and application:
Than 20CrMnTi the strength of steel, high hardenability, but the impact toughness slightly lower. Mainly used for carburizing steel, carburizing temperature after direct quenching, high bending strength, good wear resistance. In the quenching and tempering after quenching or the use of cutting of medium. Tractor industry for the manufacture of heavy duty carburized pieces of the larger cross-section and a larger force of gears, gear shafts, worm and so on.
