Grade 2507 is a Molybdenum and Nitrogen alloyed . Super-Duplex stainless steel with corrosion resistance in-line with the 6 ®Mo grades (e.g. 254 SMO ), and with a yield strength more than double that of austenitic stainless steels. It is also the strongest Duplex in welded tubular products. Characteristic properties: High mechanical strength
materials by shielded metal arc weld-ing (SMAW), gas tungsten arc welding (GTAW), plasma arc welding (PAW), flux cored wire (FCW), or submerged arc welding (SAW). 2507/P100 filler metal is suggested when welding 2507 because it will produce the appropriate duplex weld structure. Preheating of 2507 is not neces-sary except to prevent condensation ASTM A789 ASME SA 789 SAF 2507 UNS S32750 Stainless Mar 30, 2019 · 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 steel has excellent resistance to chloride
The first wrought duplex stainless steels were produced in Sweden in 1930 and were used in the sulfite paper industry. These grades were developed to primarily reduce intergranular corrosion problems in the early high-carbon austenitic stainless steels. That same year duplex castings were produced in Duplex 2507 Stainless Steel Products and Specifications A 25Cr Duplex Stainless Steel.

Jun 29, 2012 · Hyperduplex stainless steel Hyperduplex stainless steel was developed as a complement to 2507 with increased strength for use in even more aggressive conditions, such as in hot seawater, acidic chloride solutions and organic acides. Consequently most consumables for welding duplex stainless steels are over-alloyed to contain 7-10% of nickel.11 How to weld Duplex Stainless Steel - Rolled Alloys, Inc.2507 (UNS S32750) is a super duplex stainless steel designed for applications which require exceptional strength and corrosion resistance.
Apr 25, 2005 · The present study used SAF 2507 super duplex stainless steel as the base material. This particular super duplex stainless steel exhibits significantly higher corrosion resistance than early grades of duplex stainless steels . The nominal chemical composition of the alloy used in this investigation is Fe25Cr7Ni3.5Mo0.25NWCu (wt.%). SAF 2205, Super Duplex 2507 Duplex Pipe Supplier ASTM Nov 05, 2015 · SAF 2507 Super duplex pipe is a super duplex steel pipe with 25% chromium, 4% molybdenum, and 7% nickel. The common grade of super duplex steel is SAF 5027 (S32750, S32760), they have similar composition and mechanical properties.
SAF 2507 ® (UNS S32750) is a super-duplex stainless steel; a high-alloy duplex steel with a PRE value of min. 42*. The grade is characterized by very good chloride corrosion resistance, combined with very high mechanical strength. Stainless 2507, Super Duplex 2507, UNS S32750, Stainless Duplex 2507 is a super duplex stainless steel designed for applications which demand exceptional strength and corrosion resistance. Alloy 2507 has 25% chromium, 4% molybdenum, and 7% nickel.

Duplex 2507 is a super duplex stainless steel developed for applications that demand high strength and corrosion resistance. Alloy 2507 has 25% chromium, 4% molybdenum, and 7% nickel. This high molybdenum, chromium and nitrogen content causes high resistance to chloride pitting and crevice corrosion attack and the duplex structure provides 2507 Welding duplex / superduplex stainless steel to carbon The highest weld metal strength probably will be achieved with the use of a superduplex consumable. Alternatively, where such high strength is not required, a 22%Cr duplex stainless steel filler, a nickel-based filler or a 309 type austenitic stainless steel may be used. It should be noted that dilution of these highly alloyed fillers by carbon
