      45Mn quenched and tempered steel application steel plate

      45Mn medium carbon quenched and tempered steel has higher strength, toughness and hardenability than 45 steel. It can obtain better comprehensive mechanical properties after quenching and tempering. The cutting performance is still good, but the welding performance is poor, and the cold deformation plasticity is low. 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%.
