CEWELD NiCrMo 59 weld deposit composition of 59%Ni-23%Cr-16%Mo is designed to match the nickel base corrosion resistant alloy commonly known as alloy 59. The high level of Mo is similar to alloys C276 and C4 but performance in a wide range of more oxidizing media is significantly enhanced by increasing Cr to 23% in alloy 59. Total alloying exceeds the level typically present in alloy C22; it is therefore considered suitable for welding this group of alloys. Alloy 59 consumables also provide strong, tough Nb-free weld metal for dissimilar welds in Superaustenitic and Superduplex stainless steels or combinations of these with nickel base alloys. Some authorities do not allow or have discontinued use of 625 type consumables for such applications, where deleterious Nb-rich precipitates may form in diluted or partially mixed regions around the fusion boundary. Alloy C276 is possibly a more economic alternative depending on the required properties in this situation.

CEWELD® NiCrMo 686 CPT is a single-phase, austenitic Ni-Cr-Mo-W alloy with excellent corrosion resistance. Its high nickel (Ni) and molybdenum (Mo) content ensures good resistance under reducing conditions, while the high chromium (Cr) content provides resistance to oxidizing media. Molybdenum and tungsten contribute to resistance to localized corrosion, such as pitting. The iron (Fe) content is carefully controlled to optimize properties. A low carbon content helps to minimize precipitation at grain boundaries, thereby maintaining corrosion resistance in the heat-affected zones of welded joints. 

It is important to maintain a maximum heat input of 1.5 kJ/mm and a maximum intermediate temperature of 100 °C.
