Abstract: 20Cr13 stainless steel was quenched and tempered at different temperatures to obtain different hardness, and the corresponding friction and wear properties of the 20Cr13 steel were studied. The results show that when the tempering temperature ≥580 ℃, the hardness of the steel >40 HRC, the friction coefficient K is consistent with the hardness, and the wear resistance is poor. When the tempering temperature ≤550 ℃, the hardness >40 HRC, friction coefficient K deviates from the trend of hardness and tends to a constant value, the wear volume V is not affected by the hardness, and the wear resistance is high.

Key words: 20Cr13 steel, hardness, wear resistance
