Designed for applications that need superior oxidation resistance at high temperatures, our SS 446 coils are ideal for heat exchangers, furnace parts, and high-temperature ducts. We manufacture these coils using modern rolling technology and strict quality control to ensure accuracy and performance. Available in various widths, thicknesses, and surface finishes, our coils meet global quality standards. Andre Stainless is dedicated to providing excellent customer service, prompt delivery, and customized coil solutions across various industrial sectors in Singapore.
Stainless Steel 446 Coils are made from ferritic stainless steel with 23% to 27% chromium and very low carbon, enhancing oxidation resistance and thermal stability. The material also includes trace elements like molybdenum and silicon for added durability. SS 446 has a tensile strength of about 485 MPa and a yield strength of 275 MPa. It shows excellent scaling resistance up to 1100°C. While it lacks the ductility of austenitic steels, it performs reliably in situations that require thermal fatigue and creep resistance. These properties make it suitable for continuous coil-based fabrication in high-temperature systems.

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.
Stainless Steel 446 Coils are used in heat-intensive industries like metallurgy, chemical processing, and energy generation. They are ideal for fabricating components like heat exchanger tubes, furnace belts, combustion chambers, and burner liners. Due to their oxidation and carburization resistance, they are commonly found in radiant tubes, kilns, and industrial ovens. SS 446 coils are also used in automotive exhaust systems and thermal insulation wrap. Their continuous form allows for easy fabrication into tubes, ducts, and heat-resistant panels. Andre Stainless ensures that each coil provides high precision and long-lasting performance, even in the harshest heat environments.
