This have to be saved in thoughts when increasing tubes into tubesheets. Duplex 2507 is a brilliant duplex stainless-steel designed for purposes which demand distinctive strength and corrosion Saf 2507 products for onshore industry are very common as they can withstand localized corrosion and chloride ion threat in the marine environment.Duplex 2507 material for offshore industry produce the necessary strength and a very low rate of thermal expansion.Alloy 2507 material for oil and gas industry is also possible because of the low thermal expansion and pitting. As a super duplex stainless steel, the SAF 2507 combines the desirable aspects of both austenitic and ferritic grades. The higher chromium, molybdenum and nitrogen contents result in a Pitting Resistance Equivalent number (PREN) of >41, providing pitting and crevice corrosion resistance superior to austenitic and duplex stainless steels in almost all corrosive media, and a Critical Pitting Besides having a high thermal conductivity, the Super Duplex 2507 Plate has a low coefficient of thermal expansion. Along with having a mixed austenite and ferrite microstructure, the Saf 2507 Plate has a chemistry that gives it its characteristic high strength.

UNS S32750 Super Duplex 2507®, is very similar to UNS S31803 2205® Duplex. The difference between the two is the contents of chromium and nitrogen are higher in the 2507® which in turn creates higher corrosion resistance as well as a longer lifespan. 2507® is composed of between 24% to 26% chromium, 6% to 8% nickel, 3% molybdenum, and 1.2% manganese, with the balance being iron.
