About 17.35% chromium, 0.5% nickel, and trace amounts of titanium and other stabilizing elements make up the ferritic stainless steel alloy known as Stainless Steel 439. Its resistance to corrosion, especially stress corrosion cracking and intergranular corrosion, is improved by this composition. The material retains its structural integrity at high temperatures and has excellent formability and weldability. Additionally, stainless steel 439 has outstanding resistance to oxidation, which makes it perfect for settings that experience heat cycling. Because of its mechanical qualities, it can be used in demanding applications that call for durability, ductility, and long-term performance in challenging circumstances.

Stainless Steel 439 Hot Rolled Sheets have excellent corrosion resistance. The sheets are available in sizes from 3mm to 150mm in thickness and up to 2500mm in width. They are widely used in the construction and automotive industries.
Superior corrosion resistance is given by Stainless Steel 439 Cold Rolled Plates. These plates are produced in the thickness range from 0.5mm up to 6mm and in width up to 2000mm with a smoother surface finish and mechanical properties better than hot-rolled plates.
Stainless Steel 439 Chequered Sheets feature superior corrosion resistance. The available range is common from 1.5mm up to 10mm thickness in chequered pattern sheets for anti-slip purposes such as floor plates, stair treads, and various forms of stair flooring.
Stainless Steel 439 Perforated Plates give an excellent level of corrosion protection. These can be offered from 0.5mm through to 5mm in several hole sizes and patterns for different purposes like filtering, ventilation and for decorative reasons in various engineering applications.
Corrosion resistive Stainless Steel 439 Shim Sheets are manufactured using thin-precision-cut steel sheet, between 0.05mm to 3mm which are used by engineering applications at tighter tolerances to space and align.
Stainless Steel 439 Polished Plates offer excellent corrosion resistance. Plates available in thickness from 0.5mm to 6mm and widths up to 2000mm with a high-gloss finish are ideal for architectural and decorative applications.
Vinit Stainless is committed to the delivering of premium quality accompanied by comprehensive documentation for our premium Stainless Steel 439 Sheets and Plates. Some of the essential documents being: commercial invoice, packing list, fumigation certificate, heat treatment charts, quality assurance plans, and NABL approved lab test reports. These documents validate the quality and origin of the product, thereby giving confidence and trust with the valued customers. With an inherent high creep strength, as well as oxidation, our Stainless Steel 439 sheets and plates consist of test certificates, such as MTC under EN 10204/3.1B, PMI test certificates, 100 % radiography reports, and also third-party inspection.
The automotive industry makes extensive use of stainless steel 439 sheets and plates, especially for exhaust systems, catalytic converters, and other parts that are subjected to high temperatures. They are also appropriate for heat exchangers, kitchenware, and home appliances due to their resistance to oxidation and corrosion as well as their good formability and weldability. They are prized for their longevity and beautiful finish in the building and architectural industries, and are frequently utilized in both interior and exterior design components. They are also perfect for chemical processing equipment and other industrial applications that need stability and longevity due to their performance in harsh environments.
