Steel Grades in ASTM A213

Our ASTM A213 tubes are available in a plethora of steel grades, including TP304, TP304H, TP304L, TP310S, TP310HCbN, TP316, TP316H, TP316L, and more. Each grade has unique qualities suited for specific applications. Whether you require higher creep-rupture strength or enhanced corrosion resistance, UNIACERO ensures a grade perfectly tailored to your needs.

Production Tolerance of ASTM A213 Steel Pipe

ASTM A213 specifies Minimum wall thickness, namely, there is no mill under tolerance, only over tolerance, unless specified as average wall thickness is required, permissible variations from the specified average wall thickness shall be +/-10 % of the specified average wall thickness for cold-formed tubes.

Seamless tubing furnished to this specification shall conform to the requirements of specification ASTM A1016/A1016M, including any supplementary requirements.
