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 hardness of a516 grade 70 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 ℃.
Quenching is a common heat treatment process. It is the metal heat treatment process in which the hardness of a516 grade 70 metal workpiece is heated to a proper temperature and kept for a period of time, then immersed in the quenching medium for rapid cooling. Quenching can improve the strength and hardness of steel in a large range, and adjust the coordination between hardness of a516 grade 70 strength and hardness, plasticity and toughness. Quenching is generally used as the final heat treatment.
