Benefits of Stainless Steel 321 Threaded Flanges
Stainless Steel 321 Threaded Flanges offer distinct advantages. The titanium content in SS 321 prevents chromium carbide formation, ensuring corrosion resistance, even in high temperatures up to 900°C (1652°F). This makes it ideal for environments susceptible to sensitization, like welding or prolonged exposure to elevated temperatures.
The threaded connection type simplifies installation and removal, eliminating the need for welding. This feature makes it perfect for piping systems requiring frequent maintenance. With a broad range of sizes and pressure ratings, these flanges cater to diverse industry needs.
