Techalloy 625 description: Techalloy 625 (Low Iron) is used for TIG, MIG and SAW welding of nickel-chromium-molybdenum alloys. Techalloy 625HWT is a product with the same chemical and mechanical properties (Weld Metal) but with slightly different wire
characteristics suited to the hot wire TIG process. This filler metal may be used for cladding and welding dissimilar base metals such as Ni-Cr-Mo alloys to stainless and carbon steels. The Ni-Cr-Mo alloy system provides excellent resistance to oxidizing and reducing environments. The high molybdenum content provides good stress, pitting and crevice corrosion resistance.
