D667 high chromium cast iron wear-resistant electrode D-667-type high-chromium cast iron wear-resistant welding rod: This rod can be surfacing in the low, medium carbon steel, low alloy steel, high manganese steel and cast iron parts surface. Can withstand high impact wear, weld hardness HRC ≥ 55-65. 500 ℃ high temperature in the following with good resistance to abrasion, corrosion and cavitation capability. Generally increase the life of 3-8 times the weldment. This can be multi-electrode welding, welding layer 3 in order to achieve the best results (because the basic point is surfacing electrode composition, base metal composition rarely) the total thickness of surfacing not more than 1 cm is appropriate. For welding high temperature operating conditions of wear parts (such as: ring fired furnace discharge plow plow better). Welding operation by the strong impact of wear parts (such as: mining and cement crusher tooth plate) and D-266 model with the use of high manganese steel surfacing economy better. The electrode in use, according to the instructions, before the welding electrode drying, preheating welding pieces of clean, slow cooling after welding.
