Abstract
The effects of minor surface-active alloy elements Sb and Sn on hot-stamped steel grain boundary oxidation at different coiling temperatures were studied through tube sealing and soaking. The experimental results show that with the increase of coiling temperature, the grain boundary oxidation of experimental steel gradually deepens. Minor surface-active elements such as Sb and Sn in the steel can restrain the grain boundary oxidation of hot-stamped steel during hot-rolled coiling since these elements will diffuse to the grain boundary and occupy the path of oxygen diffusion inward. Furthermore, the effect of Sn on restraining the grain boundary oxidation is more obvious than that of Sb and the reason is also analyzed.
