SelectAlloy 312-C

Stainless Steel / Metal Cored / Gas Shielded

Resources

Features

  • This alloy types resulting two phase microstructure, even with considerable dilution by austenite-forming elements, promotes weld metal crack resistance and fissures.
  • 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 include welding dissimilar metals such as carbon steel to stainless steel, particularly those grades high in nickel, and welding of castings of similar composition.
