Stainless Steel 347 Pipe is columbium (niobium) stabilized austenitic stainless steel that is capable of resisting corrosion in intergranular in nature after exposure to elevated temperatures. The chemical composition involves about 17–20% chromium, 9–13% nickel, and trace amounts of columbium and tantalum. It has a carbon content of up to 0.08%, ensuring high mechanical strength and oxidation resistance. Some of the mechanical properties are tensile strength of about 515 MPa, yield strength of 205 MPa, and elongation of about 35%. The material possesses excellent resistance to creep and maintains structural integrity in high-temperature applications, making it suitable for applications involving critical industrial applications.
