本文对1Cr18mi9钢拉伸试验后，试样表面粗糙呈“桔皮”状进行了分析研究。“桔皮”状表面与晶粒粒大有一定关系。采取改锻措施可消除“桔皮”状表面缺陷。
In this paper, 1Cr18mi9 steel tensile test, the sample surface roughness was “orange peel” -shaped analysis. The “orange peel” shaped surface has a certain relationship with grain size. To take the reform measures to eliminate “orange peel” -like surface defects.
