Product Description
ASTM A213 TP347H Stainless Steel Seamless Tube
Alloy 347 (UNS S34700) is an austenitic stainless steel stabilized with columbium, offering excellent corrosion resistance in strongly oxidizing conditions. This alloy provides superior resistance to intergranular corrosion after exposure to temperatures between 800-1500°F (427-816°C) and maintains good oxidation resistance, creep strength at 1500°F (816°C), and low-temperature toughness.
Alloy 347H (UNS S3409) is the high-carbon version (0.04-0.10) designed for enhanced creep resistance and strength at temperatures exceeding 1000°F (537°C). Both alloys can be double certified for carbon content and are easily welded and machined using standard fabrication practices.
