When it comes to composition and mechanical properties, Stainless Steel 439 is a ferritic stainless steel primarily made up of iron, with 17–19% chromium and small amounts of titanium and molybdenum. Its low carbon content boosts both weldability and corrosion resistance. This alloy boasts a tensile strength of about 65,000 psi and a yield strength of around 35,000 psi, along with moderate elongation and good ductility. The Stainless Steel 439 Channels excel in oxidation resistance up to 800°C, offer better thermal conductivity than austenitic grades, and show remarkable resistance to stress corrosion cracking, especially in automotive and high-temperature settings.
