SS 321 flanges are a titanium-stabilized austenitic stainless-steel flange material, particularly useful where the flange will see elevated temperatures and welding.
The most common designation is ASTM A182 Grade F321 / UNS S32100. ASTM A182 is the relevant forging specification for flanges and other pressure-containing forged components.
Our F321 flange range includes Weld Neck, Slip-On, Blind, Socket Weld, Threaded, Lap Joint, Long Weld Neck, Orifice, Reducing, Spectacle Blind and custom-designed flanges, manufactured or supplied according to applicable international standards and customer specifications.
Typical dimensional and rating standards include ASME B16.5, ASME B16.47, ASME B16.36, ASME B16.48, EN 1092-1, DIN, JIS and applicable GB standards, depending on the project.

Typical specification limits, wt.%:
| Element | ASTM A182 F321 requirement |
|---|---|
| Carbon (C) | 0.08 max |
| Silicon (Si) | 1.00 max |
| Manganese (Mn) | 2.00 max |
