Stainless Steel 321 Tongue & Groove Flanges

Stainless Steel 321 Tongue Groove Flanges are predominantly composed of iron and chromium. However, other elements such as nickel, silicon, molybdenum and manganese are also in minor concentrations. These different metals contribute to the characteristic durability and corrosion resistance that makes Stainless Steel 321 Flanges so popular in industrial applications. Ultimately, because of these impressive properties, Stainless Steel 321 provides an ideal option for end users looking for solutions to their high-temperature welding projects.

321 Stainless Steel Tongue Groove Flanges are commonly used in many industries due to their outstanding features. They have superior corrosion resistance, excellent high-temperature strength, outstanding weldability and formability, and they also provide low rates of thermal expansion and stress rupture. These beneficial properties make Stainless Steel 321 Tongue Groove Flanges great for pressure vessels, tanks, heaters, chemical plant equipment, exhaust manifolds and more. Additionally, stainless steel flanges coated with a resin cover feature excellent insulation, resulting in a lower electrical current passing through them. This makes them suitable for vessels that house hazardous chemicals or combustible materials.
