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.
