The SS 321H flanges, made of 321H stainless steel, are commonly employed in high-temperature scenarios where strength and resistance to corrosion are crucial. These flanges find utility in various industrial settings, including pipe connectors, flange adapters, valves, pressure seals, and more. With its exceptional corrosion resistance, the SS 321H flanges demonstrate reliable performance even in harsh conditions, making them suitable for applications like petrochemical plants or saltwater environments. Moreover, their remarkable strength makes them ideal for fabricating industrial tools such as drills and lathes.

Flanges made of Stainless Steel 321H are offered in various sizes and measurements to suit different application requirements. The sizes commonly range from 1/2" to 48". Pressure ratings can reach up to 2500 psi, while temperature ratings can go up to 1200°F (649°C). Borehole lengths typically fall between 2.5" and 4.25". The choice of flange connection type determines the available materials. Threaded and socket welded flanges are usually made of Stainless Steel 321H, whereas weld neck, slip-on, and lap joint flanges are manufactured using alloys such as Alloy 825 or Alloy 20.

Flanges made of Stainless Steel 321H can withstand high temperatures, resist corrosion effectively, and be easily welded and shaped. Moreover, they exhibit exceptional strength when exposed to elevated temperatures.
