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 & Steel20CrMnTi 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 37CrNi3A Develop PaperBecause of the good hardenability, normalizing and high temperature tempering must be used to reduce the hardness and improve the machinability. It is usually used in the state of quenching and tempering. 37crni3a alloy structural steel bar can be 189-1708-1101 according to the technical requirements of GB / T 3077-1999, or military 42CrMo4 steel and 42CrMo steel difference WixSteelNormal quality steel:P< 0.035 S< 0.035 High quality steel:P< 0.025 S< 0.025 Extra high quality steel:P< 0.025 S< 0.015. It can also be seen from the above table that the contents of Si, Mn and Mo are different. The GB/T 3077 of P and S content is classified into three grades.
Jan 07, 2019 · Except quenching and tempering, 40Cr is also suitable for nitriding and high-frequency quenching. The hardenability of 40Cr steel is good, which can be reached to 28 ~ 60mm in water quenching and 15 ~ 40mm in oil quenching. When 174 ~ 229HBS, the relative machinability is 60%.
