Effect of Heat Treatment Process on Wear Resistance of 27SiMn Steel
The hardness and wear resistance of lath martensite of 27 SiMn steel quenched with different processes for different types were studied.The results show that the conventional quenched hardness is 48.7 HRC;the subcritical quenched hardness is 49.8 HRC.Hardness in two phase region quenching and high temperature quenching decreases compared with conventional quenching.The wear resistance of subcritical quenching is best.
