一种锯条用工具钢材料制备方法
Abstract:
本发明涉及一种锯条用工具钢材料制备方法，其配料组成按重量百分比为，1.8-2.0％的碳、0.35-0.5％的硅、4.2-4.3％的铬、8.2-8.3％的钨、4.2-4.5％的钒、3.5-3.8％的钼、0.2-0.3％的钴、1.3-1.4％的锰、0.12-0.15％的钛、0.8-1.0％的铜和铝、0.5-0.6％的硼、0.003-0.004％的含有铌和钇的稀土，余量为铁。通过本发明的技术方案，保证了有利于提高强度并具有一定韧性的钒、钴、钼元素及提高韧性的铜和铝进行更好的同钨、铬、钛元素的结合而减少析出。
Abstract(English):

The invention relates to a preparation method of a tool steel material for saw blades. The tool steel material for saw blades comprises the following components in percentage by weight: 1.8-2.0% of carbon, 0.35-0.5% of silicon, 4.2-4.3% of chromium, 8.2-8.3% of tungsten, 4.2-4.5% of vanadium, 3.5-3.8% of molybdenum, 0.2-0.3% of cobalt, 1.3-1.4% of manganese, 0.12-0.15% of titanium, 0.8-1.0% of copper and aluminum, 0.5-0.6% of boron, 0.003-0.004% of rare earth containing niobium and yttrium, and the balance of iron. The technical scheme provided by the invention ensures that the vanadium, cobalt and molybdenum, which are beneficial to enhancing strength and have certain toughness, and the copper and aluminum for enhancing toughness can be better combined with the tungsten, chromium and titanium so as to reduce precipitation.
