ASTM A210 A1 Cold drawing High-temperature Seamless Tubes
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 cover 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. The material used in the manufacturing of ASTM A210 Grade A1 Heat Exchanger Tubes is to be killed. The ASTM A210 Grade a1 tubes are to be produced by the seamless process, which in turn are to be marked as either hot-finished tubes or cold-finished tubes.
