Stainless Steel 347H Tubing is a higher-carbon form of stabilized austenitic stainless steel grade 347, with 17–20% chromium, 9–13% nickel, and columbium (niobium) as a stabilizer against carbide precipitation. The higher carbon content up to 0.10% improves the creep strength and performance at long-term high-temperature service. It has tensile strength of 515–750 MPa and a yield strength of about 205 MPa. The tubing has a stable mechanical property up to 900°C temperature and shows good weldability, oxidation resistance, and thermal cycling structural stability.
