To improve the service performance of Cr-series steel for cold roller, the combined effects of chromium and silicon on hardness and wear resistance of cold roll steel had been studied in this paper on the basis of MC5 cold roll steel. The results showed that, with increasing Si content the hardness tended to decrease when Cr content was about the same.
