Walid Stainless is a reliable manufacturer and supplier of Stainless Steel 446 Sheets and Plates, based in Tunis, Tunisia. The company supplies high-chromium stainless steel built for extreme heat and aggressive environments where standard grades break down. With disciplined manufacturing processes and strict quality checks, Walid Stainless delivers materials that hold their strength and integrity under punishing conditions. Known for technical know-how, consistency, and dependable delivery, the company serves power, furnace, and industrial sectors that demand heat resistance, durability, and uncompromising performance.
Stainless Steel 446 is a ferritic stainless steel with a very high chromium content, typically around 23–27%. This heavy chromium composition provides outstanding resistance to oxidation, scaling, and corrosion at elevated temperatures. The material offers good tensile strength, solid hardness, and excellent thermal stability. Stainless Steel 446 maintains structural integrity under continuous heat exposure and thermal cycling, making it highly reliable for high-temperature applications where strength and oxidation resistance are critical.

Stainless Steel 446 Hot Rolled Sheets resist high temperature oxidation and corrosion. It comes in standard sheet thickness ranging from 3mm to 50mm width up to 2000 mm and is the choice for many aggressive environments high-heat applications.
Stainless Steel 446 Cold Rolled Plates offer excellent surface finish and dimensional accuracy. Resistant to high-temperature oxidation and corrosion, these plates are available in thicknesses from 0.5 mm to 6 mm and widths up to 1500 mm. They are used in applications requiring precise tolerances.
Stainless Steel 446 Chequered Plates come in a better slip resistance, which is more rugged. They contain a raised pattern on the top surface and, thus, they possess excellent resistance against corrosion. Their common thickness is 2 mm to 10 mm while dimensions are usually 1000 mm x 2000 mm. It suits best for industrial usage and floor purposes.
Stainless Steel 446 Perforated Sheets are sheets that combine corrosion-resistance with useful ventilation and filtering design. In various hole configurations and sizes they are offered for the following usual thicknesses-1mm through 5 mm and sheet sizes up to 1200 mm x 2400 mm. More appropriate for application in architectural and industrial use cases.
Stainless Steel 446 Shim Plates are used to fill gaps and provide precise spacing in mechanical assemblies. They offer excellent high-temperature and corrosion resistance in thicknesses ranging from 0.1 mm to 2 mm and dimensions up to 1000 mm x 1000 mm, which is ideal for precision applications.
Stainless Steel 446 Polished Sheets have a smooth, reflective surface and high resistance to corrosion and oxidation at elevated temperatures. Thickness ranges from 0.5 mm to 5 mm and sizes up to 1500 mm x 3000 mm. They are widely used for decorative and high-visibility applications.
Walid Stainless is committed to an excellent customer experience with extensive documentation for its premium-quality Stainless Steel 446 Sheets and Plates. We provide necessary documents like commercial invoices, packing lists, fumigation certificates, heat treatment charts, quality assurance plans, and NABL-approved lab test reports. These documents ensure the authenticity and superior quality of our products to our worthy customers. In addition, the Stainless Steel 446 Sheets and Plates we supply are accompanied with a variety of test certificates: MTC to EN 10204/3.1b, PMI Test Certificates, 100% radiography test reports, Third Party Inspection certificates. These, in turn demonstrate our customer-driven approach and unrelenting excellence in our product lines.
Stainless Steel 446 Sheets and Plates are used in environments dominated by heat, oxidation, and corrosive gases. They are widely applied in furnace components, heat treatment equipment, kiln linings, and high-temperature baffles. The material is also trusted in power plants, petrochemical units, exhaust systems, and industrial burners. Its ability to resist scaling and deformation at elevated temperatures makes it ideal for structural and fabricated parts exposed to continuous thermal stress. Where heat is constant and failure is unacceptable, Stainless Steel 446 delivers reliable performance.
