Stainless Steel 321 Flanges
Stainless Steel 321, with UNS number S32100, also contains an addition of titanium with approximately 17% chromium, 9% nickel, in combination with carbon, silicon, manganese, phosphorus, sulfur, nitrogen, titanium, iron—the combination of all of which lends the alloy its unique mechanical properties. These include yield strength of 30ksi and a minimum tensile strength of 75ksi. Its Brinell hardness score of 217 also testifies to the fact that this alloy is hard and strong.

We deal in a wide range of dimensions and standards, like ANSI, B, ASA, and APA, for stainless steel 321 flanges. The standard nominal bore sizes of the flanges that we supplied vary from ½ inches to 48 inches. Thus, different industry applications can be covered under one roof. One of our finest products is the SS 321 blind flange. Such flanges are specifically designed to seal off the end of pipes stationarily. These blind flanges can be customised for particular modifications to fit any application perfectly.
We offer flanges manufactured from Stainless Steel 321 that turn out highly capable of supporting high pressures, available in Pressure Classes 150 to 2500. The Stainless Steel F321 Forged Flange is forged during production and especially suited to high-temperature services. Having better corrosion resistance than other stainless steel grades like 304, 316, and 310, it finds a choice for many industries.
The flanges of SS UNS S32100 pipes are broadly used in the industries, basically in petro-chemicals, food processing, sea water and marine as well as other structural applications due to its fine properties featured. We, at Sankalp Alloys Overseas, supply all scales and types of these flanges to meet all the requirements of our clients.
