Weld Star Weldstar ER2594 Super Duplex Stainless Steel TIG Filler Wire 5KG

Features and Applications Austenitic-ferritic duplex stainless steel wire characterised by a PREN (Pitting Resistance Equivalent Number) at least 40, thereby allowing the weld metal to be called “super duplex stainless steel”. Provides excellent resistance to intergranular corrosion, pitting and stress corrosion cracking in chloride environments. Over-alloyed with nickel compared to the base material to ensure the optimum combination of microstructure, mechanical properties and corrosion resistance. This alloy is widely used in applications in which corrosion resistance is of the utmost importance. Typically used in the petrochemical and offshores industries, pulp and paper and in the production of pollution control equipment.
