CEWELD® NiCrMo 686 CPT TIG is designed for applications requiring outstanding general corrosion resistance and high resistance to aggressive chemical environments. The alloy provides excellent protection against hydrochloric acid, sulfuric acid, crevice corrosion in hot, concentrated chloride-containing solutions, NaCl solutions saturated with sulfur dioxide, and oxidizing chloride media.
In addition, CEWELD® NiCrMo 686 CPT TIG offers excellent resistance to intergranular corrosion and sensitization-induced intergranular corrosion in highly oxidizing environments.
The filler metal is also suitable for overlay welding of nickel-based alloys such as Alloy 625, C276, C4, C22 and Alloy 59, as well as for welding super duplex and super austenitic stainless steels.
Typical applications include the chemical and petrochemical industries, corrosion-resistant claddings, valve seat overlays and flue gas desulfurization (FGD) systems.

CEWELD® NiCrMo 686 CPT TIG is a single-phase austenitic Ni-Cr-Mo-W alloy with exceptional corrosion resistance. The high nickel (Ni) and molybdenum (Mo) content ensures excellent resistance under reducing conditions, while the chromium (Cr) content provides resistance to oxidizing media.
The addition of molybdenum and tungsten enhances resistance to localized corrosion such as pitting. The iron (Fe) content is carefully controlled to optimize performance. A low carbon content minimizes carbide precipitation at grain boundaries, thereby maintaining corrosion resistance in the heat-affected zone (HAZ) of welded joints.
For optimal welding performance and corrosion resistance, the heat input should be limited to a maximum of 1.5 kJ/mm, and the interpass temperature should not exceed 100 °C.
