Royalfil GS- 2594 is designed for the welding of superduplex stainless steels UNS S 32750 & S 32760 (wrought) & UNS J93380 & J93404 (cast). It can also be used for welding of UNS S32550, J93370 & J93372 when not subjected to sulphurous or sulphuric acids in service. It can also be used for welding of low alloy steels to duplex steels such as E2205 & E2209 grades. In offshore applications, it gives high resistance to ‘pitting & stress corrosion cracking’ in sea water. Widely used for piping in oil & gas industry, offshore platforms, pressure vessels, valves, pumps, mining / chemical / pharmaceutical industries.
