Shape

Stainless Steel 321 Flanges are flanges made from stainless steel grade 321. This grade is an austenitic stainless steel alloy containing titanium as a stabilizing element. The chemical composition of Stainless Steel 321 typically includes around 17-19% chromium, 9-12% nickel, 0.08% carbon, and 0.5-1.0% titanium. The addition of titanium provides stabilization against sensitization and intergranular corrosion, making it suitable for high-temperature applications.

One of the main features of Stainless Steel 321 Flanges is their exceptional high-temperature strength and oxidation resistance. The titanium stabilization allows these flanges to maintain their mechanical properties and resist intergranular corrosion at elevated temperatures, up to 800-900°C (1472-1652°F). This makes 321 flanges particularly well-suited for applications in heat exchangers, furnace components, and other high-temperature environments.

Stainless Steel 321 Flanges exhibit good resistance to general corrosion in a wide range of environments, including acidic and alkaline solutions. They also show excellent resistance to pitting and crevice corrosion, especially in chloride-containing media, making them suitable for use in marine environments and chemical processing industries.

Regarding heat treatment, Stainless Steel 321 Flanges are typically solution annealed at temperatures between 950°C to 1050°C (1742°F to 1922°F), followed by rapid cooling in water or air. This treatment restores the material's properties and removes any residual stresses, enhancing its weldability and corrosion resistance.

 Stainless Steel 321 Flanges

Stainless Steel 321 Flanges find applications in various industries where high-temperature strength and corrosion resistance are essential. They are commonly used in aerospace and aircraft components, exhaust systems, and manifolds in automotive applications, as well as in petrochemical and chemical processing equipment. The flanges also find utility in power generation plants, where they are utilized in steam lines, superheaters, and boiler components due to their ability to withstand high-temperature and corrosive conditions.
