Product Description

  • Preferred over ER309 for cladding over carbon or low alloy steels, as well as for dissimilar joints that undergo heat treatment.
  • The lower carbon content reduces the possibility of intergranular carbide precipitation.
  • Strength of this low-carbon alloy; however, may not be as great at elevated temperatures as that of the columbium (niobium)-stabilized alloys or ER309.
  • Superior feedability
  • Certified Material Test Reports on all heats
