Stainless Steel 446 Coils are high-chromium ferritic stainless steels that contain about 23–27% chromium and have low carbon content. This unique blend gives them exceptional resistance to oxidation, sulfidation, and other corrosive environments at high temperatures. The alloy boasts moderate mechanical strength, good formability, and impressive scaling resistance when exposed to elevated temperatures. Typical mechanical properties include a tensile strength of around 485 MPa, yield strength of 275 MPa, and an elongation of about 20%. SS 446 is magnetic and maintains its structural integrity even under thermal cycling, making it perfect for heat-resistant applications.

SS 446 Slitting Coils are processed by slitting larger coils into narrower strips. They offer excellent resistance to high-temperature oxidation and thermal fatigue. These coils are ideal for use in applications involving high heat and severe environments.
SS 446 Hot Rolled Coils are produced through high-temperature rolling, making them suitable for heavy-duty applications. They possess high resistance to oxidation, particularly in environments where high heat is a concern. These coils are commonly used in industrial equipment and furnaces.
SS 446 Cold Rolled Coils are cold-formed to achieve a smoother finish and higher strength. These coils are ideal for precision applications, offering improved surface quality and tight tolerance. They maintain excellent resistance to heat and corrosion.
Stainless Steel 446 HR Slitting Coils are hot-rolled and then slit into narrow widths for further processing. They offer superior oxidation resistance and high strength at elevated temperatures. These coils are widely used in industries like aerospace and power generation.
Stainless Steel 446 Slitting Coils are designed for applications requiring high-temperature strength and corrosion resistance. These coils are slit into precise widths and are ideal for high-stress environments. They maintain their mechanical properties even at extreme temperatures.
AISI 446 Slitting Coils are manufactured from high-alloy stainless steel, offering excellent resistance to thermal fatigue and oxidation. They are commonly used in applications such as furnaces, kilns, and combustion chambers. The slitting process ensures flexibility for different industrial needs.
We are committed to delivering the highest quality Stainless Steel 446 Coils to our clients. For their excellent quality, these coils undergo a series of stringent testing processes before dispatch. These tests include hardness testing, chemical analysis through spectro analysis, positive material identification (PMI) testing, flattening testing, micro and macro tests, pitting resistance testing, flaring testing, and intergranular corrosion (IGC) testing. Besides that, we also provide third-party inspection certificates for the assurance of our clients in respect of the excellent quality and reliability of our Stainless Steel 446 Coils for a wide variety of industrial applications.
These Stainless Steel 446 Coils find extensive use in industries that demand superior heat and corrosion resistance. They’re commonly used in furnace components, heat exchangers, annealing boxes, and kiln linings within thermal processing units. In the petrochemical and chemical sectors, you’ll find them in exhaust manifolds, incinerators, and flue gas systems. Thanks to their ability to endure oxidation and thermal fatigue, SS 446 coils are also utilized in power plants, boiler equipment, and refinery systems. Their strength and durability in extreme temperatures make them a go-to material for challenging, high-temperature industrial environments.
