SelectAlloy 316L-CS_LNG

Stainless Steel / Submerged Arc / Flux Shielded

Resources

Features

  • Specially formulated to produce good weld metal toughness via strict weld metal chemical composition control.
  • Resulting deposited ferrite is consistently between 3-7 FN when measured either by predictive methods or using magnetic induction methods.
  • Low C, < 0.04 wt%, minimizes carbide precipitation (sensitization) which makes the weld metal more resistant to intergranular corrosion.
  • The addition of Mo improves resistance to pitting and crevice corrosion compared to type 308 stainless steel.
  • Applications for this alloy type include fabrication or repair of cryogenic components of similar composition that require weld metal toughness maintained at temperatures of -320°F.
  • The recommended flux is ArcFlux BF-38, an aluminate-fluoride-basic flux without Cr or other alloy compensation.
