ER 308L Tig Wire

ER 308L TIG wire is a stainless steel filler material used in TIG welding. It’s designed for welding 304 and 304L grade stainless steels. The “L” signifies low carbon content, reducing carbide precipitation and increasing resistance to intergranular corrosion. This wire provides strong, ductile welds with excellent corrosion resistance.

ER 308L Tig Wire Chemical Compositions:

The chemical composition of ER 308L TIG wire typically includes the following elements:-

  • Carbon (C): ≤ 0.03%
  • Chromium (Cr):5-21.0%
  • Nickel (Ni):0-11.0%
  • Manganese (Mn):0-2.5%
  • Silicon (Si): ≤ 0.65%
  • Phosphorus (P): ≤ 0.03%
  • Sulphur (S): ≤ 0.03%
  • Iron (Fe): Balance

These elements provide the wire with its desired properties, such as corrosion resistance and weld ability.

Physical Properties:

ER 308L TIG wire has the following physical properties:-
