The specified ASTM A210 GR.A1 Seamless Steel Tubes are designed to be used in several applications as either boiler or as superheater tubes. The ASME SA210 Gr A1 Superheater Tubes that are manufactured under this specification also covers minimum wall thickness, and tubing sizes, boiler flues including safe ends, arch as well as stay tubes. While the specification for these ASME SA210 Grade A1 Pressure Vessel Tubes takes into account both the tensile strength and hardness properties but these two properties are applicable to certain size limitations. Material used in the manufacturing of ASTM A210 Grade A1 Heat Exchanger Tubes are to be killed. The ASTM A210 Grade a1 tubes are to be produced by seamless process, which in turn are to be marked as either hot finished tubes or cold finished tubes.

 

Application

Apply to Boiler Tubes, Seamless Steel Tubes, Steel Tubes, and Superheater Tubes.
