ASTM A213 designates grades T5, TP304, etc. Grades with the letter H have a higher creep rupture strength than grades without H. ASME SA213 seamless pipe is chrome molybdenum alloy pipe. ASTM A192 is the same as ASME SA-192 and is the standard specification covering seamless carbon steel boiler and superheater tubes of minimum wall thickness for high pressure service.
