AWS A5.9 ER347

A 5kg pack of 347 Stainless Steel TIG Welding Rods available in a variety of diameters. Designed to be used for welding niobium stabilised stainless steel.  The stabilisation effects of niobium reduce the risk of weld decay (intergranular corrosion) which can diminish the structural integrity of the weld. In addition this element also acts as a strengthening agent to the finished weld.  347 TIG Filler Rods are suitable for welding both 321 and 347 stainless steels.  It also has high resistance to stress corrosion cracking which presents a risk in environments where exposure to chlorides and other corrosive chemicals could be a factor.


Comprised of Chromium and Nickel which provide excellent properties to repel the effects of corrosion, plus it also has good resistance to high heat and oxidation.  Suitable for welding both 321 Titanium stabilised stainless steel and  347 Niobium stabilised stainless steel.  Providing excellent resistance to the risk of weld decay (intergranular corrosion).  This issue occurs at the microscopic level where the formation of carbide interferes with the welds molecular structure, creating tiny holes invisible to the naked eye. Subsequently compromising weld integrity.  Available in a variety of diameters.

Available in 5kg packs in the following diameter options -:

  • 1.6mm
  • 2.4mm
  • 3.2mm

347 Stainless Steel TIG Filler Wire is used in a wide range of industries including Chemical, Oil, Gas as well as Nuclear. In applications such as but not limited to welding stainless steel pipe in particular where a backing ring or purging gas is needed to ensure an impurity free weld is achieved.  347 rods are a great addition for this purpose. Furthermore they are also used in the food industry, for pressure vessels, food processing plants and domestic stainless steel equipment.
