Khaled Stainless is a well-respected manufacturer and supplier located in Cairo, Egypt, specializing in high-quality Stainless Steel 439 Sheets and Plates. These products are perfect for applications that demand superior corrosion resistance, heat stability, and a long lifespan. With a strong focus on precision engineering and a commitment to global standards, Khaled Stainless guarantees that every 439 sheet and plate offers outstanding durability, formability, and dimensional accuracy. Crafted using cutting-edge processing technology, these materials are ideal for moderately corrosive environments and high-temperature applications. The company serves a variety of industries, including automotive, appliance manufacturing, exhaust systems, and industrial fabrication, consistently delivering reliable stainless steel solutions.
Stainless Steel 439 Sheets and Plates are made from a ferritic stainless steel alloy that boasts a high chromium content and titanium stabilization, which significantly improves intergranular corrosion resistance and weldability. This grade is known for its good tensile and yield strength, enhanced oxidation resistance, and excellent performance under high temperatures. Its ferritic structure provides strong resistance to stress corrosion cracking and ensures good thermal conductivity. Additionally, Stainless Steel 439 offers superior formability compared to standard ferritic grades, maintaining stability and toughness throughout fabrication processes.

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.
Khaled 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.
These Stainless Steel 439 Sheets and Plates are widely utilized in applications that require robust heat resistance, corrosion protection, and structural integrity. You’ll often find them in automotive exhaust systems, catalytic converter components, mufflers, and heat shields, thanks to their impressive performance at elevated temperatures. They’re also commonly used in household appliances, kitchen equipment, water heaters, and furnace components. Their excellent formability and resistance to chloride-containing environments make them ideal for industrial enclosures, ductwork, and various fabrication projects where long-lasting durability is essential.
