In industrial applications, stainless steel flanges are an essential component. They come in various types, each with its specific characteristics and benefits. Among the most popular stainless steel flanges are 321 and 321H flanges. These flanges are widely used in various industries due to their exceptional strength, corrosion resistance, and heat resistance properties.
Stainless Steel 321 Flanges are classified into six types - Weld Neck Flange, Slip-On Flange, Blind Flange, Socket Weld Flange, Lap-Joint Flange, and Threaded Flange. These flanges offer excellent corrosion resistance and strength, making them suitable for applications in extreme temperature and pressure environments.

Stainless Steel 321H Flanges are primarily used in high-temperature applications. Its higher carbon content offers better resistance to thermal shock and intergranular corrosion resistance. It’s typically used in exhaust manifolds, thermal oxidizers, furnaces, heat exchangers, and combustion systems. The 321H grade is also used in the aerospace and chemical industries for critical applications where thermal loading is a concern.

The 321 and 321H grades of stainless steel flanges are widely used across several industrial applications. Other application areas include pulp and paper mills, power generation plants, and marine engineering.
The 321 and 321H Grades of Stainless Steel Flanges are known for their superior corrosion resistance, high tensile strength, and excellent creep strength. They offer excellent resistance to intergranular corrosion and are suitable for high-temperature environments. Furthermore, stainless steel 321H flanges have a lower risk of sensitization due to their higher carbon content.
Stainless Steel 321 and 321H flanges are highly versatile, offer superior corrosion resistance, and are suitable for several industrial applications. In the food processing, chemical processing, oil and gas, or pharmaceutical industry, the 321 and 321H grades of stainless steel flanges offer so much in terms of long-term performance, durability, and cost-effectiveness.
