Description and applications*
Austenitic stainless steel filler metal most often used to weld base metal of similar composition, even if it can be used even for dissimilar welding. It shows excellent resistance to oxidation, especially at high working temperatures (lower than 1000°C) due to its high Cr content, as well as excellent corrosion resistance even when hot.
It is fully austenitic and therefore sensitive to hot cracking (it calls for minimal heat input during welding).
This grade may be used for:
• welding and overlay of stainless steels of similar chemical composition;
• dissimilar welding;
• welding of pipe, plate and fittings used in the of industrial furnaces and similar applications working at elevated temperatures (e.g. boiler parts, annealing chambers, heat exchangers, fused salt treatment installations).
Weldable base materials*
* Illustrative, not-exhaustive list
300 series austenitic stainless steel for welding (e.g. AISI 310, 304); mild and carbon steels for overlay works.

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. Customized labels are available upon request
