SS 321/321H Flanges
Flanges can be employed industrially to achieve a wide range, whether by coupling different piping segments together or controlling the general flow of gas or liquids. If you're looking for a highly resistant flange that will be very durable and thus highly reliable, Stainless Steel 321 and 321H Flanges can be just what you need.
Flanges of stainless steel 321 are very versatile metal alloys that are strong, durable, and corrosion-resistant. Besides primarily being used individually, most applications also involve using two types of alloys, which include stainless steel 321 (UNSS32100) and stainless steel 321H (UNS S32109), among other alloys. The group to which they are classified consists of the same family of austenites, which are significant additions in alloying and molybdenum.

The primary difference between these two grades is the carbon content. Both have lower levels of carbon than grades 304 or 316, although Type 321 has slightly more than Type 321H. This variation becomes significant whenever welding applications are concerned: with its higher carbon content, Type 321 can suffer from intergranular corrosion if it is not welded correctly. Stainless Steel 321H Flanges hold great importance in places operating at very high temperatures, where no other types of metals would be capable of taking a high heat level without the damage being caused to its physical structure. For example, Stainless Steel 321 Slip-on Flanges would see service for use in boilers or other processing units where admissible temperatures could go as high as 1,000 degrees Fahrenheit or 538 degrees Celsius.
They also find applications in most chemical processing plants because they are corrosion-resistant and, therefore, very much suited for containing corrosive substances. In addition, the Stainless Steel 321 Socket Weld Flanges are used in food processing plants since they do not stain or contaminate food products with heavy metals like the other metals are known to do. The benefits of Stainless Steel 321H Spectacle Blind Flanges are not limited to resisting temperature or protecting from corrosion. Moreover, these flanges have strength-to-weight ratios that hold high pressure due to light and strong flanges without adding too much extra weight, which creates added pressure on other parts of the machinery or system.
SS 321H Blind Raised Flanges are one of the best proven against most materials, be it Titanium Gr 2 Flanges or Nickel Alloy Flanges, which makes them the best for any budget-conscious operation to have a reliable solution. We, Sankalp Alloys Overseas, are a leading manufacturers, suppliers, stockists, and exporters assuring us to provide superior quality Stainless Steel 321 and 321H Flanges for the dissimilar needs of industries.
