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 ℃)

Performance characteristics
1. High strength: SA210Gr.A1 seamless steel pipe has high strength
and can withstand greater pressure and load weight.
2. Corrosion resistance: The surface coating of the steel pipe has
good corrosion resistance and can effectively resist the corrosion
of chemical substances such as acid, alkali and salt.
3. High temperature resistance: SA210Gr.A1 seamless steel pipe has
high high temperature resistance and can maintain stable
performance in high temperature environment.
4. Low temperature resistance: the steel pipe can also maintain
good performance in low temperature environment, and is suitable
for use in some cold areas.
5. Good connection performance: SA210Gr.A1 seamless steel pipe
adopts advanced connection technology, which can achieve fast and
simple connection and improve the reliability of the pipeline
system.
6. Environmental protection: The materials of the steel pipe are
environmentally friendly materials, which will not cause pollution
and harm to the environment and human body.
