20Cr Alloy Structure Steel China Steel Grade Standard GB

Hardening of GB Alloy structural steel 20Cr; First quenching heated slowly to 880°C, Then after adequate soaking at this temperature quench in oil or water. Temper as soon as tools reach room temperature. Second quenching heat to 780-820°C then quenching in oil or water. Tempering of 20Cr Alloy structural steel 20CrMoTi Gear Steel Bar, GB3077 round bar - World Iron & 20CrMnTi gear steel is a commonly in accordance with the standards of the former Soviet union in China according to GB/T 3077, GB/T 5216-2014 and GB/T 33160-2016 (gears for wind power generation). 20CrMoTi steel is a type of low-carbon alloy steel which widely used in gear with good strength and toughness and higher hardenability, in order to meet the requirements of wear resistance, corrosion
