Consumables designed to match the composition and properties of alloy 686. Its high **Ni** and **Mo** provide good resistance in reducing conditions, and high **Cr** offers resistance to oxidizing media. **Mo** and **W** resistance to localized corrosion such as pitting. Low**C** helps minimize grain boundary precipitation to maintain corrosion-resistance in the heat-affected zones of welded joints. This alloy also provides a tough Nb-free weld metal for dissimilar welds in superaustenitic and superduplex stainless steel or combinations of these with Ni base alloys. It also offer exceptional as-welded resistance to sulfuric or hydrochloric acids, to mixtures of the two, and to crevice or pitting corrosion in hot concentrated acid chloride solutions. Mainly used in chemical and petrochemical processing, pollution control, oil and gas extraction, oil refining, and in marine environments. They are also useful for dissimilar metal welding, offering protection against preferential weld-metal attack when used for joining Mo-containing alloys or alloy-clad steels.
