• Minimal carbon not greater than .02% to protect against corosion.
  • Ideal for buttered passes and overlay work.
  • Typically used to weld 309 series stainless steels.
  • Has the same qualities as ER309 but with the lower carbon content deemed necessary in many chemical applications.
  • Preferred over ER309 for cladding over carbon or low alloy steels, or dissimilar joints that are heat treated.

  • Hazmat: No
