Description and applications*
* Illustrative, not-exhaustive list

Austenitic stainless steel filler metal with a significant amount of manganese,
making the all-weld metal in most cases fully austenitic. It is a non-magnetic
metal, with high ductility.
This grade may be used for:
• moderate-strength welds with good crack resistance between dissimilar steels
such as austenitic manganese steel and carbon steel forgings or castings;
• joining of austenitic stainless to carbon steels;
• joining of wear plates;
• applications as a buffer layer under cladding.

Marking
Each filler rod for GTAW welding is durably marked with an identification traceable to the unique product type. Welding filler materials wound on spools or in coils are durably marked on the coil or spool with an identification traceable to the unique product type.
The outside of each unit package is suitably labelled with at minimum the following data: grade, diameter, heat, lot no., classifications.
CE marking type-testing performed and available.
Customized labels are available upon request.
