FEATURES & APPLICATIONS

6317 TIG rod is an extremely low carbon stainless steel Alloy with extra high molybdenum content added to provide superior corrosion resistance. It is especially well suited for welding stainless steel pipe wherever a backing ring or a purge gas is required in order to provide impurity free weldments. This is necessary during stainless steel pipe welding in the chemical and petro-chemical industries.

  • A special 317L TIG alloy coated with our unique Vari-Flow fluxing system.
  • A very special TIG wire that eliminates the expense and wasted time associated with purging pipes with inert backing gasses.
  • Easy to handle 18 inch (450mm) length works in multiple positions without having to bend the wire.
  • Can be ordered in grade 308L as item number 6308.
  • Any other grade of stainless can be manufactured in 100 pound (45kg) per diameter minimum quantities.
