1.4410 Duplex Plateis amongst one of the most commonly used duplex grade steel in the market. Duplex grade steel is a specific kind of steel that has ferrite and austenite components in … KNPC approved Super Duplex 2507 Pipe Fittings Manufacturer in India, Check Price list of Super Duplex S32750 Reducer, Tee, Pipe Cap & Stub End, Supplier of Super Duplex S32750 Elbow in Mumbai CLI - SAF 2507® has improved corrosion resistance properties when compared to duplex 2205 type materials, or even to URANUS® 47N. It is designed for service in severe corrosive conditions. The alloy is particularly resistant to stress corrosion cracking and crevice corrosion.

Duplex stainless steels have a combined chemical composition of a balance phased Sandvik SAF 2507 (Plate sheets, wirelines, billets, bars, strip steel).

SAF derives from S andvik A ustenite F errite. The nominal chemical composition of SAF 2205 is 22% chromium , 5% nickel , 3.2% molybdenum and other alloying elements such as nitrogen and manganese . [1] lowest PRE value will be limiting for the actual pitting corrosion resistance.

The high mechanical properties and corrosion resistance of duplex stainless steel depends on adding Cr, Mo, Ni and N. However, this alloy elements, also 

the PRE-values for other duplex stainless steels of the 25Cr type which are not "super-duplex". Equivalent Standards: DIN 17458, GOST 9941-81, GOST 9940-81, EN 10216-5, ASTM A790, ASME SA790, DIN 17456: Material: S32750: Equivalent Materials: X2CrNiMoN25-7-4, 1.4410, SAF2507, F53: Related Products: stainless steel tube, stainless steel pipe, heat exchanger steel tube, ASTM A789 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 Temperature exceeding … 2021-03-05 Super duplex 2507 density is 0.282 lb/in³ (7.80 g/cc).

They offer high resistance to this potential cause of sudden failure along with a greater resistance to pitting corrosion than is available with 316. And this is combined with high strength which allows for optimum material utilisation.
