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. 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.

5140 Steel - Din 1.7035 - JIS SCr440 - Songshun Steel

The 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%. Mechnical PropertyGB/T 3077-1999:Sample Size mm GB/T 11251 30CrMnSiA alloy steel plates - BEBON steelGB/T 11251 30CrMnSiA alloy steel plates are medium carbon tempered steel with high strength and poor welding performance. After quenching and tempering, 30CrMnSiA alloy steel plates have high strength and toughness and good hardenability. GB/T 11251 30CrMnSiA alloy steel
