一种高强度钻头用合金钢
技术领域
本发明涉及钻头材料技术领域，特别涉及一种高强度钻头用合金钢。
背景技术
电钻是一种应用广泛的电动工具，在建筑、加工等领域有广泛的应用，电钻的主要原理是通过电动机的转动，带动驱动作业装置，从而使钻头刮削物体表面以洞穿物体，钻头是电钻必不可少的部件之一；而电钻在使用过程中，要承受动机与被钻物体的径向阻力，钻头折断是最常见的损害方式，这是因为现使用的钻头用工具钢在保证要具有一定强度的情况下，脆性提高而韧性不足，因此，钻头容易出现折断，而且钻头的磨损情况也是影响钻头效率的原因之一。
发明内容
本发明要解决的技术问题是提供一种能够延长使用寿命且降低成本的高强度钻头用合金钢。
为解决上述技术问题，本发明的技术方案为：一种高强度钻头用合金钢，其创新点在于：其含有的化学元素成分及其质量百分比为：碳0.087-0.095％、硅0.02-0.03％、钴0.025-0.03％、铬0.03-0.04％、镍0.02-0.04％、钒0.001-0.002％、钨0.035-0.04％、钒0.05-0.06％、锆0.013-0.018％、铌0.024-0.025％、硫0.45-0.5％、磷0.08-0.1％、余量为铁。
进一步的，碳0.09％、硅0.025％、钴0.028％、铬0.035％、镍0.03％、钒0.001％、钨0.04％、钒0.055％、锆0.016％、铌0.024％、硫0.5％、磷0.09％、余量为铁。
