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

CHALLENGES WELDING DUPLEX AND SUPER DUPLEX

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.

Super Duplex 2507 Stainless Steel (UNS S32750 and UNS

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
