Priminox Overseas is a known stockist of SS 321 Flanges, which is stabilized against chromium carbide formation by the addition of titanium. A limitation with our Stainless Steel 321 Slip On Flanges is that titanium does not transfer well across a high temperature arc, so is not recommended as a welding consumable. These Stainless Steel 321 Blind Spectacle Flanges is also advantageous for high temperature service because of its good mechanical properties. Our Stainless Steel 321 Weld Neck Flanges has extensive use in aircraft parts, such as exhaust systems where operating temperatures are higher than 800 Degree F and where corrosive conditions are not too severe; also because of its resistance to scaling and vibration fatigue. These Stainless Steel 321 Lap Joint Flanges is used primarily in applications involving continuous and intermittent service temperatures within the carbide precipitation range of 800 Degree F – 1500 Degree F (427 Degree C – 816 Degree C). Stainless Steel 321 Orifice Flanges is similar to type 304 stainless but with a titanium addition of at least five times the carbon content. These Stainless Steel 321 Blind Raised Flanges displays good oxidation resistance at elevated temperatures has excellent resistance to intergranular corrosion and has excellent weldability. Its resistance to sensitization, coupled with its higher strength at high temperature, makes Stainless Steel 321 Ring Type Joint Flanges suitable in application where SS 304 will become sensitized, or where SS 304L has insufficient hot strength.
