SelectAlloy 16-8-2-C

Stainless Steel / Metal Cored / Gas Shielded

Resources

Features

  • Alloyed to produce good hot-ductility properties for resistance against weld or crater cracking under restraint conditions despite a typical ferrite number (FN) of the weld deposit of <5FN.
  • 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 stainless steel grades such as 16-8-2, 316, and 347 in high-pressure, high-temperature piping systems.
