Stainless Steel 446 Sheet, Plate, Coil Supplier


Stainless Steel 446 Sheet, Plate, and Coil are premium ferritic stainless steel materials intended for high-temperature oxidation, and corrosion resistance. Known for their hardness and heat resistance, they are commonly used in harsh industrial applications. Preston Pipes & Alloys, a reputed name among SS 446 Sheet Suppliers, provides superior quality products in accordance with international standards. These coils, sheets, and plates are used in industries like oil and gas, petrochemical, chemical, power generation, energy, pharmaceutical, pulp and paper, food processing, aerospace, and refining, as they are strong and work well in tough conditions.


AISI 446 stainless steel contains a high level of chromium, along with carbon, manganese, nitrogen, silicon, nickel, phosphorus, sulfur, and iron as the balance. This composition gives the alloy excellent scaling resistance and stability at elevated temperatures. With a density of 7.5 g/cm³, a yield strength of 40,000 psi (275 MPa) and a tensile strength of 75,000 psi (485 MPa), the material provides strong mechanical performance. It has an elongation of 20% and a melting point of 1510°C (2750°F), which allows it to be used in high-heat applications without deteriorating its structure. These qualities make it a reliable choice for industries that demand both mechanical strength and chemical resistance, which is why many trust aisi 446 Stainless Steel Plate Suppliers for consistent quality.
