Stainless Steel 321 Circle and Rings are made of austenitic steel alloy as a plate or sheet. These solid structures come in different sizes and thicknesses and find multiple industrial applications. While the circles are hollow with varying internal and external diameters, they possess exceptional corrosion resistance and stability at high temperatures.
Stainless Steel 321 is an austenitic Nickel-Chromium alloy that is further stabilized with Titanium to maintain quality. Adding Titanium reduces the intergranular corrosion that may occur after heating due to carbide precipitation. Stainless Steel 321 Rings possess superior qualities such as high resistance against corrosion, reduced intergranular corrosion, stability at higher temperatures, and outstanding strength. These rings are extensively used in various pressure and temperature ranges, where they can handle stress in extreme conditions. Moreover, they are suitable for corrosive applications and possess boosted strength with rigid and complex structures of varying thicknesses.
Stainless Steel 321H Rings, conversely, are acid corrosion-proof and have phase stability in aqueous corrosion. They are resistant to water and seawater corrosion and are commonly used in marine applications. Additionally, they are ideal for various chemical processes containing chlorides.
Stainless Steel 321 Circle and Rings are easily formable and weldable, making them suitable for general corrosion and pitting. They possess an antirust surface, which makes them resistant to chloride stress corrosion. Their rupture strength and durability improve their serviceability in several thermal and corrosive conditions.
