(PDF) Microstructural Analysis of Inconel 625 Nickel Alloy

In this study, Inconel 625 nickel alloy and UNS 31803 duplex stainless steel (DSS) dissimilar pairs were welded with MIG welding process. Weld metal, obtained with ERNiCrMo-3 filler wire, was Duplex Stainless Steel 2205 Alloy (UNS S32205 S31803) - SAF duplex 2205 stainless steel (UNS S32205, formerly known as UNS S31803, usually referred to as "alloy 2205") has a mixed microstructure of austenite and ferrite and is a two-phase alloy based on the Fe-Cr-Ni series. Alloy 2205 material has lower nickel and molybdenum content than austenitic stainless steel and has similar corrosion resistance.

Figure 6 Vickers hardness profile of weldment 4. CONCLUSION The fusion and HAZ zone occurred by welding austenitic Inconel 625 nickel alloy and the austenitic-ferritic UNS 31803 duplex stainless-steel material pair with the ERNiCrMo-3 filler wire, provide adequate mechanical properties. UNS S31803 Duplex Stainless SteelYorkshire Steel are suppliers of UNS S31803, a chromium nickel molybdenum austenitic ferritic grade. It combines improved resistance to stress corrosion cracking, pitting, crevice corrosion and high strength in comparison with other stainless steel grades. UNS S31803 grade duplex resists chloride environments and sulphide stress corrosion.

Oct 16, 2018 · Duplex stainless steel (UNS S31803, S32205, S32750, S32900) combines the advantages of Ferrite and Austenite steel. Its duplex structure is conducive to obtaining high strength and stress resistance. In addition, higher content of chromium, nitrogen and molybdenum increases corrosion performance and duplex steel also has good welding performance.
