Mbemba Stainless stands out as a reputable manufacturer and supplier of Stainless Steel 439 Sheets and Plates in Kinshasa, Congo. They specialize in delivering top-notch ferritic stainless steel solutions that are designed for exceptional performance. The SS 439 grade is celebrated for its remarkable corrosion resistance, impressive high-temperature strength, and enhanced weldability, making it a great fit for a variety of industrial and structural uses. Mbemba Stainless offers these sheets and plates in a range of thicknesses, sizes, and finishes to cater to specific project needs. With a strong commitment to quality, durability, and customer satisfaction, the company guarantees reliable and cost-effective SS 439 products for sectors like automotive, fabrication, construction, and general engineering.
Stainless Steel 439 Sheets and Plates are ferritic stainless steel alloys that typically contain 17–19% Chromium, along with low carbon content and added Titanium or Niobium for stabilization. This unique composition boosts corrosion resistance, oxidation resistance, and heat tolerance. SS 439 showcases good yield and tensile strength, excellent weldability, and better formability compared to other ferritic grades. It also offers superior resistance to stress corrosion cracking and retains its strength even at elevated temperatures. These mechanical properties make SS 439 an ideal choice for applications that demand thermal stability, durability, and a long service life.

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.
Mbemba 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.
Stainless Steel 439 Sheets and Plates are a go-to choice in industries that need materials that can withstand heat, resist corrosion, and keep costs down. You’ll often find them in the automotive world, where they play a crucial role in exhaust systems, catalytic converter parts, and heat shields, thanks to their impressive performance at high temperatures. In the realms of construction and architecture, they’re used for everything from cladding and roofing to stylish interior panels. SS 439 also finds its way into kitchen gear, household appliances, ducting, furnace components, and heat exchangers. Plus, these sheets and plates are essential in fabrication, industrial processing equipment, and engineering projects that demand long-lasting durability and stability.
