ASTM A789 2507 Super Duplex Tubing 1.4410 Super Duplex Stainless Steel Tube
Duplex Alloy 2507 is a super duplex stainless steel with 25% chromium, 4% molybdenum and 7% nickel. It has excellent resistance to chloride stress corrosion cracking, high thermal conductivity, and a low coefficient of thermal expansion. The high chromium, molybdenum and nitrogen levels provide excellent resistance to pitting, crevice and general corrosion. The impact strength is also high. Duplex Alloy 2507 is not recommended for applications which require long exposures to temperatures above 570 °F because of the risk of a reduction in toughness.
