SelectAlloy 2594-C

Stainless Steel / Metal Cored / Gas Shielded

Resources

Features

  • This superduplex stainless steel has a Pitting Resistance Equivalent Number (PREN) of > 40. PREN = Cr + 3.3(Mo +0.5W) + 16N. The high PREN is an indicator of superb resistance to pitting in aqueous chloride-containing environments.
  • Metal cored benefits include the ability to successfully bridge gaps when part fit up is not as designed, higher travel speeds with subsequent lower heat inputs at equal amperages, and ability to join thin materials.
  • Applications for this alloy type include welding of UNS S32750 and 32760 (wrought), UNS J93380 and J93404 (cast). It can also be used to weld UNS S32550, J93370, and J93372 when not subject to sulfurous or sulfuric acids in service.
  • Dissimilar welds are another application in welding carbon and low alloy steels to duplex stainless steels as well as to weld “standard” duplex stainless steel such as UNS S32205 and J92205, especially for root runs in pipe.
