Iron and Steel Group Co., Ltd., Laiwu 271100, China)Р Abstract: The metallographic structure, tension test properties and fractography of 410S hot rolled strips produced in laboratory and ofР industrial production were analyzed pared. The results showed that through changing the rolling process, that is, decreasingР the rolling temperature of last passes and increasing the reduction in pass for promoting the strip recrystallization, the recrystallizedР structure increased the properties of the strip markedly and softening the strip. The structure of the strip produced by improvedР process was most recrystallized ferrite and part granule carbide separated along the grain boundary.Р Key words: 410S stainless steel; hot-rolling; recrystallization; finishing temperature; reduction in passР 28
