Item Details

  • This alloy is valuable for welding dissimilar joints, especially if one of the base metals is a stainless high in nickel content. The deposit is two-phase, high in ferrite. Even with considerable dilution with austenite forming elements, such as nickel, the microstructure is two-phase and thus highly resistant to weld metal cracks and fissures.


  • MIL-E-19933E


  • Arcos 312 is intended for welding stainless steels to mild steels and for welding high strength steels that are difficult to weld with ferritic electrodes
  • This wire also joins stainless steels where high strength or wear resistance is essential. Service temperatures should be below 800˚F to prevent formation of secondary brittle phases


  • Protect yourself and others read the safety data sheet prior to using this product.
