“…After being heated to 950 °C and water quenched, slatted martensite is obtained, and its substructure is high-density dislocation [17]. At 200 °C tempering, because of the carbon atoms image dislocation segregation and eliminating part of the internal stress, so the plasticity gradually increased.…”

Fasteners are widely used in automobile, electronic and other fields, and the demand for high performance fastener materials is increasingly urgent. 10B21 mild steel has the advantages of good plasticity, obvious heat treatment effect and so on. It is used to produce fasteners below grade 9.8. In this paper, the domestic 10B21 boron steel as the research object, through quenching, tempering and other heat treatment, change its structure from ferrite to tempered martensite, in order to improve the strength and hardness.
