SelectAlloy 309LCR-C

Stainless Steel / Metal Cored / Gas Shielded


  • Low carbon (C), < 0.03 wt%, minimizes carbide precipitation (sensitization) which makes the weld metal more resistant to intergranular corrosion.
  • The addition of titanium (Ti) in this product further reduces the possibility of sensitization, promotes better arc stability, and reduces the propensity of cracking in welding dissimilar materials when problematic.
  • 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 the welding of refinery and chemical processing equipment, furnace components, and automotive exhaust applications. Dissimilar welding of austenitic stainless steels to carbon, low alloy, and even some cast iron steel have been successfully achieved.
