These consumables exhibit an exceptional combination of characteristics, providing resistance to metal-to-metal wear, corrosion, erosion, and thermal shock. Specifically engineered for temperatures up to 800°C, they consist of chromium, nickel, and molybdenum alloys, collectively imparting excellent mechanical properties for enhanced corrosion and wear resistance. The resulting weld deposit demonstrates robust creep strength, making it well-suited for enduring high-temperature environments. With an optimal ferrite content in the joint, this filler material finds application in a range of scenarios, including heavy structural fabrications, oil rigs, boilers, pressure vessels, and cryogenic storage tanks. Notably, it surpasses similar fillers in terms of superior impact values at low temperatures. Widely utilized for surfacing valves and valve seats in the oil and gas industries, as well as for enhancing the durability of screw conveyors, augers in rubber and plastic industries, saw teeth in wood industries, and critical components like cams, shafts, tappets, and push rods in engines, among other applications.

Similar in composition to deposits made using ERCoCr-A electrodes and rods except for a slightly higher percentage of carbides.

Chromium and tungsten carbides (approximately 16%) in an austenitic type matrix.

It is used to surface valves and valve seats for oil& gas industries, screw conveyors and augers for rubber and plastic, saw teeth for wood industries, cams, shafts, tappets and push rods for engines, etc.

Prior to engaging in the welding process, it is imperative to meticulously cleanse the joint surface and its immediate vicinity. Complete removal of grease, oil, crayon marks, sulfur compounds, and any extraneous substances is paramount. Exercise caution to prevent contact between the joint area and copper or copper-bearing materials. Ideally, although not obligatory, the alloy should find itself in the solution-annealed state before initiating the welding procedure. The necessity for preheating arises only when the base metal temperature descends below 0°C. During welding, it is advisable to maintain relatively low interpass temperatures. This approach is designed to cultivate optimal conditions for a seamless welding operation.
