硬质合金钨钢YG20C耐磨性钨钢 YG20C钨钢板
Chemical composition: the WC: 80 Co: 20 density: 13.4 to 13.7 g/cm3 bending strength: 2200 N/cm2 or higher hardness: p 82 HRA YG20C advanced model-making materials. Without heat treatment, internal and external hardness is uniform. Used in large batch production. Is suitable for the production of standard parts, bearings and blunt with cold heading and cold, cold press mold. YG20 is one of the die steel, belongs to the tungsten cobalt cemented carbide. Specific as part of the tungsten carbide carbide, without heat treatment, internal and external hardness is uniform. Used in large batch production, stamping die for the production, such as stamping parts, instruments, watches the spring piece, etc.; Coining battery shell, such as toothpaste mould using performance: the use of high strength, impact toughness good purposes, for example: used for cold heading die, stamping die, such as cold heading screws, nuts, cold punching steel ball, warhead, stamping parts, instruments, watches the spring piece, etc.; Punch the battery shell, toothpaste, mould, etc.
YG20C高X制模材料。不经热处理，内、外硬度均匀一致。用于批量大的生产。适用于标准件、轴承等制作用的冷镦、冷冲、冷压模具的制作。
