321
are useful in connecting pipes, pumps, valves and other measuring equipment in tubing and piping systems. These flanges are welded or screwed to pipes to make stronger joints. Stainless Steel 321 Flange is similar to grade 304 but it is stabilized by titanium additions. SS 321 Flanges have 18% chromium and 8% nickel that offer excellent strength and corrosion resistance over a comprehensive range of media.
We have the largest stock of these flanges including 321 Stainless Steel Slip On Flanges, 321 Stainless Steel Weld Neck Flanges, 321 Stainless Steel Socket Weld Flanges, and many more. All these flanges are manufactured as per national as well as international standards like ASME, ASTM, ANSI, AISI, etc.
