Welding wire for HK40 and HP45

The high temperature resistant cast alloys HK40 and HP45 modified are used for over 40 years with great succes in turbine parts and other high heat applications. This casting part must often be welded to a other alloy (dissimilar welding) and is often done with the wrong filler metal. Nicro 617 is the right filler metal to obtain reliable results and is also suited for dissimilar welding.
