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
Low temperature tempering:150-200 Cool in ari, get 61-66HRC hardness. Hot work and cold work of 20CrMnTi Alloy Gearing steel; GB 20CrMnTi steel can hot worked at 205 to 538°C, 20CrMnTi Bearing/Gearing steel can be cold worked using conventional techniques in the annealed or normalized conditions. Mechanical Properties
4140 Alloy Steel 1.7225 SCM440 42CrMo4 - OTAI The hardness of the steel can be increased if it has lower tempering temperature. For example, tensile strength of 225 ksi cab be achieved by tempering at 316°C (600°F), and a tensile strength of 130 ksi can be achieved by tempering at 538°C (1000°F). Hardening AISI 4140 alloy steel can be hardened by cold working, or heating and quenching.

SAE AISI 4340 Steel Properties, Heat Treatment, Equivalent The high hardness of 4340 alloy steel requires that the material be welded in the annealed or tempered state and then heat treated to resist martensite formation and cold cracking. However, as in motor shaft applications, under quenching and tempering conditions, 4340 steel typically use high preheating in low hydrogen processes.GB/T 3077-2015 English Version, GB/T 3077-2015 Alloy GB/T 3077-2015 English Version - GB/T 3077-2015 Alloy structure steels (English Version):GB/T 3077-2015, GB 3077-2015, GBT 3077-2015, GB/T3077-2015, GB/T 3077, GB/T3077, GB3077-2015, GB 3077, GB3077, GBT3077-2015, GBT 3077, GBT3077
