20Cr Alloy Structure Steel - Special steel china supplier

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 20MnCrti Steel Gear Steel Case Hardening Steel MalaysiaLow 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 Paper

Because 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 40Cr Alloy Structure Steel-GB/T 3077-China Steel material40Cr Alloy Structure Steel-GB/T 3077-China Steel material.

Temper as 40Cr Steel Equivalent, Mechanical Properties & Chemical 40Cr Alloy Steel. 40Cr steel is a kind of Chinese GB standard alloy steel for engineering and machinery purpose, and one of the most widely used steel grades.For 40Cr material hardness, specifications and equivalent, please see the table below. After quenching and tempering treatment, 40Cr steel has good comprehensive mechanical properties, low temperature impact toughness, low notch

42CrMo4 DIN 1.7225 Steel Round Bar Plate Material

42CrMo4 steel is super high strength alloy steel with high hardenability and toughness and it has no temper brittleness. And it also be called DIN 1.7225 steel. After quenching and tempering, it will get high fatigue strength. Its impact toughness is great at low temperatures. 5140 Steel - Din 1.7035 - JIS SCr440 - Songshun SteelThe ways of heat treatment for 1.7035 steel are normalizing, annealing, quenching, tempering and etc. Quenching it at the temperature of 850 and oil cooling. Tempering at the temperature of 520, then water-cooling and oil cooling. After quenching, the surface hardness of it is 52-60HRC. Nitrogen Treatment. 5140 steel can nitriding, and A brief inroduction of 40Cr alloy structual steel SHEW-E 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%.
