RW 310 - Nr.1.4842

RW 310 Stainless Welding Wire: Welding Wire for 25Cr-20Ni Heat-Resistant Stainless Steels

RW 310 is used for welding heat-resistant stainless steels alloyed around 25% Cr and 20% Ni.

High Chromium Content and Heat Resistance High chromium content provides good corrosion resistance at elevated temperatures.

Fully Austenitic Structure Because it is fully austenitic, hot-cracking sensitivity must be considered and operation above 1000°C is not recommended.

Applications Typical applications include industrial furnaces, annealing chambers, molten salt plants, boiler components and heat exchangers.
