ASME SA312 TP310S / UNS S31008 Stainless Steel Seamless Pipe Industrial

ASTM A312 / ASME SA312 TP310S / UNS S31008 Stainless Steel Seamless Pipe

ASTM A312/ASME SA312 TP310S is a specification for seamless austenitic stainless steel pipes, ndicating a low-carbon variant of the 310 grade, optimized for enhanced weldability and resistance to carbide precipitation. TP310S seamless pipes are critical for industries requiring durability under extreme heat and corrosion. Their low-carbon composition, seamless integrity, and compliance with rigorous standards make them a reliable choice for demanding applications.

Key Features

• High-Temperature Performance: Suitable for continuous service up to 1035°C and intermittent use up to 1150°C.

• Corrosion Resistance: Excellent in oxidizing environments (e.g., furnaces) but less effective in reducing/chloride-rich conditions compared to grades like 316.

• Seamless Construction: Manufactured via hot extrusion or rotary piercing, ensuring superior strength for high-pressure applications.

• Low Carbon Content: Reduces sensitization risk, making it ideal for welding without post-weld heat treatment in most cases.
