Stainless Steel 446 Sheet, Plate, Coil Supplier

Ferritic stainless steel grade 446 is a common specification for applications where superior resistance to oxidation and high temperatures is needed . It’s extremely tough and heat resistant, making it a go-to for demanding industrial environments. With an experienced Stainless Steel Plate Supplier like Preston Pipes & Alloys, you can be assured of the highest grade stock complying with stringent international requirements. Grade 446 sheets and coils are commonly used in power generation, heat treatment equipment, petrochemical processing and other high temperature industrial applications where normal stainless steels may not provide appropriate oxidation resistance. 

The good scaling resistance is a consequence of the chemical composition, in particular the high content of chromium in balance with controlled contents of manganese, silicon and nitrogen . Density: 7.5 g/cm³ Yield Strength: 40,000 psi (275 MPa) Tensile Strength: 75,000 psi (485 MPa) Add a 20% elongation rate and a huge 1510°C (2750°F) melting point and you have a material that won't lose its structural integrity under extreme thermal stress. These properties make Grade 446 a popular material for demanding technical applications needing reliable high temperature performance.

Grade 446 plates and coils are available in a wide range of sizes and configurations to suit different fabrication requirements. You can source thicknesses from 4 mm right up to 100 mm, with widths stretching to 3500 mm and lengths up to 6000 mm. Depending on the application, surfaces can be finished in anything from standard 2B or No.1 hot-rolled to precision mirror, etched, or brushed textures often backed by protective plastic films. The alloy can be formed into strips, foils, perforated sheets, or custom-cut rings, meaning you can get exact dimensions tailored to your blueprint.

The quality assurance is directly related to the performance of the material. Before leaving the plant, every single sheet is subjected to comprehensive destructive and non-destructive testing to verify its chemical composition and mechanical limits. These heavy duty materials require equal maintenance in the shipment, being properly packed in sturdy hardwood crates, protective wraps or steel-strapped bundles to prevent damage in transit. The correct choice of grade and surface treatment for your working conditions ensures long-term durability from the first installation.
