20Cr Alloy Structure Steel China Steel Grade Standard GB

The 20Cr alloy steel will get MAX 250 HB Brinell hardness. 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. 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

During carburizing, the grain size of GB/T 3077 20Cr alloy steel plate tends to grow. Therefore, secondary quenching is required to improve the toughness of GB/T 3077 20Cr alloy steel

Steel plate - Sunny Steel

Quenching and tempering is a two-step heat treatment process. In the quenching step of this process, steel is heated to a temperature between 1,500-and 1,650-degrees Fahrenheit, then rapidly cooled with water. In the tempering step, the steel is then re-heated to a below-critical temperature between 300 and 700 degrees and air-cooled. gbt 11251 15cr steel application - Hot Rolled Steel FactoryGB/T 11251 20Cr hot rolled structure steel plates - Bebon gbt 11251 15cr steel applicationGB/T 11251 20Cr hot rolled structure steel plates ,GB/T 11251 20Cr hot rolled structure steel plates are widely used to manufacture carburized parts (oil quenching) that have high requirements for core strength, bearing surface wear, section below 30mm gbt 11251 15crmn steel exporter Carbon steel,mild steel sae 1045 tool round bar price of 1kg steel bar.
