The quality grade symbols of Q235 steel plate are A, B, C and D respectively. Different grades represent different impact temperatures. , Q235A is not required for impact toughness test; Q235B is required for impact toughness test at room temperature (20 ℃); Q235C is required for impact toughness test at 0 ℃; Q235D is required for impact toughness test at - 20 ℃ For the above-mentioned B, C and D grade steels, Akv ≥27J is required under different temperature requirements At different impact temperature, the impact value is also different,ASTM A 283 C, A 570 Gr. 33 carbon steel.
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 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 ℃.
