| description | The invention belongs to the field of stainless steel manufacturing processes, and particularly relates to a free-cutting austenitic stainless steel bar and a preparation method thereof. The stainless steel comprises the following chemical components in percentage by weight: less than or equal to 0.030 percent of C, 0.015 to 0.030 percent of S, less than or equal to 0.035 percent of P, less than or equal to 1.00 percent of Si, 1.00 to 2.00 percent of Mn, 16.50 to 18.00 percent of Cr, 10.50 to 14.00 percent of Ni, 2.00 to 2.50 percent of Mo, 0.5 to 0.7 percent of Ti and the balance of Fe. And the balance of Fe and other inevitable impurities. The sulfur-containing free-cutting austenitic stainless steel bar has the characteristics that the sulfur-containing free-cutting austenitic stainless steel bar has good cutting performance, the content of inclusions is not obviously increased, and the sulfur-containing free-cutting austenitic stainless steel bar can be applied to the aerospace field with high requirement |
