Our Stainless Steel 347H Tubing is made up of Chromium (17–20%), Nickel (9–13%), Carbon (0.04–0.10%), and Niobium (Columbium) for stabilization, along with trace amounts of Manganese, Silicon, and other elements. This unique composition gives it excellent resistance to intergranular corrosion and stress rupture, even at high temperatures. In terms of mechanical properties, it boasts a tensile strength of about 515 MPa, a yield strength of 205 MPa, and an elongation of around 35%. The higher carbon content in 347H enhances its creep strength, making it a reliable choice for sustained high-temperature service in critical environments.

Stainless Steel 347H Tubing Uses

You’ll find Stainless Steel 347H Tubing widely used in applications that demand high-temperature strength and resistance to thermal fatigue. It’s perfect for heat exchangers, superheaters, boiler tubes, and pressure vessels in the power generation and petrochemical sectors. In chemical processing, it’s utilized for piping and reactor components that face acidic or oxidizing conditions. The aerospace, refinery, and oil & gas industries also rely on 347H tubing for turbine components and high-stress environments. Thanks to its niobium stabilization, it prevents carbide precipitation during welding, while the high carbon content boosts mechanical stability during extended exposure to elevated temperatures.
