The Stainless Steel 439 sheets and plates from Emilio Stainless are made from a titanium-stabilized ferritic stainless steel alloy, featuring around 17–19% chromium and low carbon content. The inclusion of titanium enhances weldability and boosts resistance to intergranular corrosion. SS 439 is known for its good oxidation resistance, impressive thermal conductivity, and moderate strength. It boasts a tensile strength ranging from about 430–590 MPa and a yield strength of approximately 275 MPa. These characteristics, along with better fabricability compared to other ferritic grades, make SS 439 a smart and cost-effective choice for a variety of structural and functional applications.
