Alloy 347 (UNS S34700) is a columbium-stabilized austenitic stainless steel that provides excellent general corrosion resistance with enhanced performance in strongly oxidizing conditions. It demonstrates superior resistance to intergranular corrosion after exposure to temperatures between 800-1500°F (427-816°C) and offers good oxidation resistance, creep strength at 1500°F (816°C), and low-temperature toughness.
Alloy 347H (UNS S3409) is the high-carbon variant (0.04-0.10) developed to improve creep resistance and strength at temperatures above 1000°F (537°C). The carbon content can often be double certified.
This alloy cannot be hardened through heat treatment but responds well to cold working methods. It offers excellent weldability and machinability using standard fabrication practices.
