ASTM A182 F321, F321H Forged Stainless Steel Weld Neck Raised Face Flanges DIN2631
ASTM A182 F321, F321H Forged Stainless Steel Weld Neck Raised Face Flanges DIN2631
ASTM A182 F321 (UNS S32100) Stainless Steel Flange is titanium stabilized austenitic stainless steel with good general corrosion resistance. It has excellent resistance to intergranular corrosion after exposure to temperatures in the chromium carbide precipitation range of 427 - 816°C. The alloy resists oxidation to 816°C and has higher creep and stress rupture properties than F304 and F304L. It also possesses good low temperature toughness.
ASTM A182 F321 stainless steel flange is an austenitic alloy that helps in increasing the strength and easy attachment of different piping equipments. F321 Stainless Steel Flanges are stabilized with titanium and have outstanding resistance to intergranular corrosion. They also have good corrosion resistance properties. These flanges are efficient in connecting pipes and allow good room for easy modification and cleaning. They have excellent mechanical properties and are durable for long periods.
