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 gives weld metal with high mechanical strength and excellent crack resistance.
It is a non-magnetic metal, with high ductility, high corrosion resistance and very low ferrite content.
This grade may be used for:
• welding of heterogeneous stainless steels;
• joining and surfacing applications on heat resistant Cr-steel and austenitic steels;
• joining unalloyed/low-alloyed or Cr-steel to austenitic steel applications where a good resistance to atmosphere and to corrosive media (e.g. automotive industry) is needed;
• usage as a buffer layer prior to 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.
