With a commitment to precision-engineered stainless steel products, Varun caters to a variety of industries, from automotive to construction. Their Stainless Steel 439 sheets are perfect for applications that demand oxidation resistance and durability in high-heat environments. Varun adheres to international standards, offers custom dimensions, and ensures quick service throughout the Middle East, solidifying its reputation as a reliable name in the stainless steel sector.
The Stainless Steel 439 Sheets and Plates are primarily made up of 17–19% chromium and low carbon, with titanium added for stabilization. This ferritic stainless steel grade is known for its superior resistance to intergranular corrosion and oxidation, especially in automotive exhaust settings. Its mechanical properties boast a tensile strength ranging from 415–620 MPa and a yield strength of 205–275 MPa. SS 439 also provides good formability and weldability, and it’s magnetic, making it a great choice for applications that require moderate strength alongside high corrosion resistance.
