Description
441 Stainless Steel Sheets is a dual-stabilized ferritic stainless steel containing 18% chromium and low-carbon content. This grade demonstrates excellent high-temperature strength, surpassing that of grades 409L and 439. It also exhibits good corrosion resistance in various exhaust gas environments and strong oxidation resistance at elevated temperatures. While ferritic steels are not inherently robust at higher temperatures, the addition of columbium, along with suitable solution annealing, significantly enhances long-term stability.
Grade 441 is dual-stabilized with niobium and titanium to ensure good weld ductility and resistance to intergranular corrosion in the weld heat-affected zone. It can be formed using a broad range of processes, including roll forming, mild stretch-bending, and common drawing operations.
Our 441 Grade Stainless Steel Coils and Sheets feature a unique composition enhanced with niobium and titanium, providing exceptional weld flexibility and resistance to corrosion. These versatile sheets and coils can be effortlessly shaped using a variety of manufacturing methods like roll forming and bending, making them the perfect choice for a wide range of applications. Whether used in construction, automotive, or industrial sectors, our 441 stainless steel sheets ensure reliable performance and longevity.”
