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.
Stainless 446 Plate, Stainless Steel 446 Coil, and related products are available in a
wide range of specifications. Thickness ranges from 4 mm to 100 mm, widths from 1000 mm
to 3500 mm, and lengths from 2000 mm to 6000 mm. Surface finishes include 2B, 2D, BA,
No.1, No.4, No.8, mirror, checkered, embossed, hairline, sandblast, brushed, and etched.
Finishes are offered in hot rolled, cold rolled, satin, and other types, often with
protective plastic coating. Forms include coils, foils, rolls, plain sheets, shim
sheets, perforated sheets, chequered plates, strips, flats, blanks, and rings.
Customized dimensions are also available to meet unique project needs.
Each Stainless Steel 446 Sheet goes through extensive quality testing, including
mechanical, and chemical tests, to make sure it meets standards. To ensure that products
are safe while they are being shipped, it is packed in wooden boxes, plastic wraps or
bundles with steel straps. From the manufacturing process to the final installation
site, careful inspection and secure packaging maintain the product in good condition.
For high-quality stainless steel materials that deliver performance and reliability,
choose the right grade and finish to match your industrial requirements
