Stainless Steel 439 Sheets and Plates are crafted with precision to cater to industries that demand durability, corrosion resistance, and outstanding forming capabilities. These products, made from ferritic stainless steel, are stabilized with titanium, which not only improves weldability but also helps prevent intergranular corrosion. Renowned for their ability to resist oxidation and heat, Stainless Steel 439 offers an economical yet dependable option. You’ll find these sheets and plates widely used in automotive, architectural, and industrial settings, providing long-lasting performance, structural integrity, and cost-effective solutions for challenging environments.
The composition of Stainless Steel 439 Sheets and Plates primarily includes iron, chromium (17–19%), and small amounts of titanium for stabilization. This titanium addition helps to prevent carbide precipitation and boosts corrosion resistance. This grade is known for its good oxidation resistance at high temperatures and retains strength even under thermal stress. Its mechanical properties feature a tensile strength of about 415 MPa and a yield strength of 275 MPa, along with excellent ductility and formability. The ferritic structure ensures good thermal conductivity and lower thermal expansion, making these sheets and plates ideal for fabrication and high-temperature applications.
