AWS/ASME A 5.9 ER 316L
EN 12072: W 19 123 L
FEATURES & APPLICATIONS |
6316 Tig rod is an extremely low carbon stainless steel Alloy with molybdenum 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 316L 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.
