MW520 Martensitic TIG Welding Rod
MasterWeld MW520 is used for welding martensitic precipitation, or age, hardening stainless steels.
These steels have high strength and some of the grades exhibit corrosion resistance comparable to 304 austenitic stainless steel.
The MasterWeld MW520 would only be used for applications that can be subsequently heat treated, if it is not possible to carry out a PWHT then an alternative wire should be considered (eg. MasterWeld ER2209 or ER2594).
Typical applications include pumps, impellers and hydraulic equipment in the oil & gas, petrochemical and marine industries.
