ASTM A209 / A209M, ASME SA209 T1, T1a, T1b is the standard applicable to seamless carbon-Molybdenum Alloy-Steel Boiler and Superheater Tubes.

ASTM A192,ASME SA192 High-Pressure Seamless Boiler And Superheater Tubes are made by the seamless process and shall be either hot-finished or cold-finished, as specified.

S355J2H is a low-alloy structural steel pipe with excellent mechanical properties and reasonable chemical composition. It is often used to manufacture pressure vessels, transmission pipelines and various engineering machinery.

ASTM A213 covers seamless ferritic and austenitic steel boiler, Boiler Tube, and heat-exchange tubes, designated Grades T5, TP304, etc. Grades containing the letter, H, in their designation, have requirements different from those of similar grades not containing the letter, H.
