Abstract

The invention relates to a novel chalcogenide easily cut steel and iron material. The novel chalcogenide easily cut steel and iron material consists of the following ingredients in percentage by mass: 0.13-0.16 percent of C, 0.9-1.35 percent of Mn, 0.06-0.12 percent of Si, 0.07-0.11 percent of P, 0.28-0.33 percent of S, 0.04-0.11 percent of Zr, not larger than 0.006 percent of Al, not larger than 0.005 percent of N and the rest of Fe based on the 100% total mass percentage. The easily cut steel and iron material is provided and prepared with economical advantage, and the cutting performance is improved under the condition of ensuring mechanical performance.

Description

technical field [0001] The invention relates to a novel sulfur-based free-cutting iron and steel material, which belongs to the field of metallurgical materials. Background technique [0002] The sulfur-based free-cutting steel not only reduces the cutting force and cutting temperature of the material, improves the tool life, but also reduces the surface roughness of the workpiece and improves chip handling. Therefore, it has been widely used in various industries and departments such as automobiles, machinery, precision instruments, and defense industries. It accounts for 70% and 90% of the total production of free-cutting steel in the world and my country respectively. In free-cutting steel materials, the composition, shape (aspect ratio) and distribution of inclusions have a significant impact on the mechanical properties of the steel, cutting resistance, wear of cutting tools and surface finish of the workpiece. However, there are still some problems in the new sulfur-...
