Stainless steel 446 sheets and plates have many advantages, making them ideal for high temperature applications. They provide exceptional resistance to oxidation, corrosion and scaling, even in extreme environments. The high chromium content increases the ability to withstand high temperatures and increases durability. These materials also provide excellent thermal conductivity and strength while maintaining structural integrity in extreme conditions. In addition, Stainless Steel 446 is resistant to chloride stress corrosion and cracking, making it suitable for use in industrial furnaces, heat exchangers, and other complex applications where reliability is critical.
These materials are widely utilized in industries where high strength, corrosion resistance, and heat tolerance are essential. In chemical processing, you’ll find them in reactors, heat exchangers, and piping systems that come into contact with aggressive chemicals. The marine sector relies on them for components exposed to seawater and for structural supports. In construction, they’re used in frameworks, bridges, and high-temperature structural parts. They also play a vital role in power generation, particularly in furnace components and boiler systems, where resistance to oxidation is crucial.
