DAIKOWT 686

Tailored with precision, these consumables are designed to replicate the composition and characteristics of alloy 686. The heightened levels of Nickel (Ni) and Molybdenum (Mo) offer robust resistance in reducing conditions, complemented by the substantial Chromium (Cr) content providing resilience against oxidizing media. Notably, the inclusion of Molybdenum (Mo) and Tungsten (W) enhances resistance to localized corrosion, specifically addressing issues such as pitting. The low Carbon (C) content plays a pivotal role in minimizing grain boundary precipitation, ensuring the preservation of corrosion resistance within the heat-affected zones of welded joints. Remarkably versatile, this alloy also furnishes a durable Nb-free weld metal, suitable for dissimilar welds involving superaustenitic and superduplex stainless steel, or combinations thereof with Nickel-based alloys. Furthermore, it exhibits exceptional as-welded resistance to sulfuric or hydrochloric acids, their mixtures, and displays resilience against crevice or pitting corrosion in hot concentrated acid chloride solutions. Predominantly applied in chemical and petrochemical processing, pollution control, oil and gas extraction, oil refining, and marine environments, these consumables are invaluable. Their utility extends to dissimilar metal welding applications, providing protection against preferential weld-metal attack, particularly when joining Molybdenum-containing alloys or alloy-clad steels.
