Effect of Si Content on Microstructure and Wear Resistance of Cold Roll Steel with 5%Cr

Abstract:

The effect of Si content on structure and wear resistance of cold roll steel with 5%Cr by using vacuum arc melting furnace had been studied in this paper. Results showed that with increasing Si content martensite got coarsening and the number and content of primary carbide increased; The type of primary carbide was M7C3 and Si mainly dissolved into martensite by XRD analysis; The wear resistance was effectively improved while Si content increased. The appropriate Si content in cold roll steel with 5%Cr was 1.5%~2％.
