Tungsten carbide welding rod: Tungsten carbide tubular electrode has excellent abrasion resistance and are widely used in metallurgy, petroleum, coal and other industrial sectors to withstand severe wear workpiece surface, can significantly increase the life of the workpiece. Most wear-resistant high temperature seems to be: 938 molybdenum chromium boron (MO-Cr-B) alloy hardfacing electrodes Description: molybdenum, chromium boron hardfacing electrodes, molybdenum, chromium boron as the main raw material, the use of the latest science and technology developed from the AC-DC dual-use welding layer with high hardness, good toughness, high temperature and abrasion characteristics used in the surfacing of carbon steel, alloy steel, cast iron, cast steel surface.
