Table 2 shows the chemical composition of SAF 2507 superduplex stainless steel. Se hela listan på azom.com ASTM A789 ASME SA 789 SAF2507 UNS S32750 (EN 10216 – 5 1.4410) Stainless Steel is super duplex stainless steel with 25% chromium, 4% molybdenum, and 7% nickel designed for demanding applications which require exceptional strength and corrosion resistance, such as chemical process, petrochemical, and seawater equipment. The Chemical Composition of super duplex 2507 is Molybdenum, Mo 3 – 5, Chromium, Cr 24 – 26, Nickel, Ni 6 – 8, Nitrogen, N 0.24 – 0.32, Manganese, Mn 1.20 max, Silicon, Si 0.80 max, Copper, Cu 0.50 max, Sulfur, S 0.020 max, Carbon, C 0.030 max, Phosphorous, P 0.035 max and Iron, Fe balance. 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 Duplex 2507 stainless steel exceeds the standard requirements of stainless steel, with a SAF 2507 alloy that combines the benefits of chromium, molybdenum and nickel within a single steel material. Super duplex 2507 is highly useful in corrosive environments where resistance to crevice corrosion and pitting is a must.

SAF 2507 Bolts have high strength, resistance to pitting, stress corrosion cracking, erosion and corrosion fatigue, crevice corrosion resistant. 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.

Duplex 2507 possesses excellent mechanical properties. Often a light gauge of 2507 material can be used to achieve the same design strength of a thicker nickel alloy. Sandvik’s 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 ductility.
