40Cr steel is one of the most widely used steels for mechanical operations. The hardenability of this steel is outstanding, it can be hardened to Ф28 ~ 60mm when water quenching, and Ф15 ~ 40mm when oil quenching. In addition to quenching and tempering treatment, 40Cr steel is also suitable for cyanidation and high frequency quenching treatment. 40Cr steel has good cutting performance. When the hardness is 174 ~ 229HB, the relative machinability is 60%. The steel is suitable for making medium-sized plastic molds.
20G steel is a common carbon steel used to manufacture boilers. The performance of 20G steel is basically the same as that of 20# steel. The requirements for impact toughness, strain aging impact value and cold bending of 20G steel are increased. The yield ratio of 20G steel is slightly higher, and certain fatigue and corrosion resistance are required for A572 Gr 42 CS steel carbon plate steel to ensure the safe operation of boilers. 20G steel is suitable for manufacturing marine boilers, steam boilers and other boiler accessories with pressure less than 6Mpa and wall temperature less than 450 ℃.A572 Gr 42 CS steel carbon plate
