摘要
通过对 2 0MnK—U形钢试样在不同加热温度下的顶端淬透性试验及整体淬火后试样截面U形硬度曲线的测定 ,研究了亚温淬火时加热温度对 2 0MnK钢淬透层深度的影响。
According to the hardenability experiment on 20 MnK—U shaped steel specimen's end in different heating temperature,and the detect the U_shape hardness curve of specimen's section after whole hardened,the paper studied the effects of temperature on the hardened depth of 20MnK specimen by subcritical quenched.
