2507 (UNS S32750) is a super duplex stainless steel designed for applications which require exceptional strength and corrosion resistance. 2507 is a 25% chromium, 4% molybdenum, and 7% nickel alloy resulting in excellent resistance to chloride pitting and crevice corrosion attack.
Alloy 2507 Duplex Stainless Steel Plate - Sandmeyer SteelSandmeyer Steel Company stocks the only full line of 2507 duplex plate in North America with plates in thicknesses from 3/16" (4.8mm) through 3" (76.2mm). Alloy 2507 duplex is a cost-effective alloy vs. 904L or 6% moly super austenitic stainless steels. Available thicknesses for Alloy 2507:
Although super duplex grades have good high temperature oxidation resistance, like other duplex stainless steels they suffer from embrittlement if held for even short times at temperatures above 300°C. If grade 2507 becomes embrittled this can only be rectified by a full solution annealing treatment. Heat Treatment Solution Treatment (Annealing)
Better and more cost-effective machining with super-duplex Jan 15, 2018 · Super-duplex grades are so-called because they are more resistant to pitting corrosion than duplex stainless steels. Sandviks own super-duplex stainless steel, Sandvik SAF 2507, has a chemically balanced metallurgy to give it characteristics which are advantageous for machining such as higher mechanical strength, low hardness and
