686
Description
Solid wire for Nickel based alloy 686
It is designed to match Alloy 686. The high alloy levels of Cr, Mo , W result in increased resistance to pitting, crevice, intergranular attack and general corrosion. It is also suitable for welding duplex, super-duplex and super-austenitic stainless steels, as well as nickel alloys and to overmatch 625, C276, C4, C22 and 59 alloys. This consumable also provides a tough Nb-free weld metal and is of great value for service environments requiring general corrosion- resistance in HCl or sulfuric acid.
