ASTM A210/ASME SA210 GR.A1 Carbon Steel Seamless Tube for Boiler
SA210 GR.A1 is a steel grade in the ASMESA-210 standard, which is a small diameter carbon manganese steel tube for boilers and superheaters, and a pearlite type heat resistant steel. The plasticity and toughness are equivalent to 20G. The production process of the steel is simple and the cold and hot workability is good. Replacing 20G with it can reduce the thickness of thin walls, reduce material consumption, and also improve the heat transfer status of boilers.
Used for heating surface tubes of low and medium pressure boilers (with a working pressure generally not exceeding 5.88Mpa and a working temperature below 450 ℃); Used for heating surface pipes, economizers, superheaters, reheaters, petrochemical industry pipes, etc. of high-pressure boilers (with working pressure generally above 9.8Mpa and working temperature between 450 ℃ and 650 ℃)
