Stainless Steel 439 Pipes are made from ferritic stainless steel that’s stabilized with titanium, enhancing both corrosion resistance and formability. Typically, they contain 17-19% chromium and a low carbon content of less than 0.03%, with titanium added (0.1-0.3%) to prevent carbide precipitation. Their mechanical properties boast a tensile strength of 415 MPa, yield strength of 205 MPa, and an elongation of 20%. With excellent oxidation resistance at high temperatures and good weldability, SS 439 is a go-to choice for applications that require durability, thermal efficiency, and resistance to stress corrosion cracking in tough environments.
