Super Duplex 2507 flanges are made of a stainless steel alloy containing 25% chromium, 4% molybdenum, and 7% nickel. Duplex 2507 is known for its high strength and excellent localized corrosion resistance to chloride. This alloy is widely used for its yield strength which is twice that of annealed austenitic stainless steels, like 304 and 316 stainless.
Super Duplex 2507 Strength
Offering high impact and mechanical strength, Super Duplex 2507 flanges can be used at temperatures up to 570°F before you will see a reduction in strength.
Super Duplex Corrosion Resistance
Chloride corrosion resistance is one of the key attributes of Super Duplex 2507 flanges due to its specialty metal makeup. The high molybdenum, chromium and nitrogen content of Super Duplex provides these flanges excellent resistance to chloride corrosion such as pitting and crevice attack, while its ferritic structure makes it very resistant to stress corrosion cracking in warm chloride environments. Super Duplex 2507 flanges also provide uniform corrosion protection from organic acids such as formic and acetic acid, plus inorganic acids, especially those containing chlorides. In addition, 2507 flanges are highly resistant to carbide-related intergranular corrosion due to their low carbon content (0.020% in weight).
