ASTM A312 SEAMLESS STEEL PIPE

ASTM A312 SEAMLESS STEEL PIPE

ASTM A 312 seamless steel pipe is mainly applies to the use of high temperature and general corrosion seamless and welded austenitic stainless steel male pipe.

Level mainly TP304H, TP309H, TP309HCb, TP310H, TP310HCb,TP316H, TP321H and TP347 suitable for high-temperature use.

The nominal wall thickness greater than 9.5mm seamless process manufacturing the TP321 and TP321H grade steel nominal possession of the lower strength requirements.
