310 & 310S Stainless Steel Flanges Manufacturer & Supplier

Why Choose Our Stainless Steel 310 / 310S Flanges?

Stainless Steel 310 and 310S Flanges are high-alloy steels with a minimum of 10.5% chromium content, offering exceptional resistance to oxidation and corrosion. These flanges are widely used across various industries in the United States, including food processing, petrochemicals, power generation, and marine applications.

  • 310 SS Slip-On Flanges – Known for excellent corrosion resistance in food-grade and high-temperature environments.
  • 310 SS Threaded Flanges – Rust-resistant and ideal for applications requiring ease of assembly without welding.
  • 304H SS Weld Neck Flanges – Designed for high-pressure applications, offering strong mechanical strength.
  • 304H SS Blind Flanges – Suitable for systems requiring secure sealing and shutoff capabilities.

Unlike carbon steel, our UNS S31000 and S31008 Flanges (310/310S) form a passive chromium oxide layer on the surface, preventing rust and ensuring long-term durability in low-oxygen and high-salinity environments. These flanges are ideal for U.S. offshore oil rigs, chemical processing plants, and heat treatment applications.
