It is a corrosion-resistant stainless welding wire used for welding heat-resistant stainless steels containing approximately 25% Cr and 20% Ni. Thanks to its high chromium (Cr) content, it provides very good corrosion resistance, particularly at elevated temperatures. This grade is fully austenitic and therefore sensitive to hot cracking. Although its corrosion-resistance temperature limit is high, it should not be used at temperatures exceeding 1000°C under any circumstances. Typical applications include industrial furnaces, annealing chambers, plants handling molten salt processes, boiler components, and heat exchangers.
