| Abstract: | The modified containing tungsten added V-N microalloying Cr5W tool steel-0.70～0.90C，≤1.00Si，0.20~0.60Mn，4.50~5.50Cr，1.00~1.50W，≤0.15Mo，≤0.3V，300×10-6～350×10-6N has been developed. Test results indicated that the structure of modified Cr5W steel quenched at 960 ℃ was martensite + carbide,of which the average HRC hardness was 63.5,and the average HRC hardness of modified Cr5W steel after temper at 180 ℃ was 63.2 higher than hardness(average HRC 62.3)of 180 ℃ tempered Cr5 steel(0.70~0.90C，≤1.00Si，0.20～0.60Mn，4.50~5.50Cr，0.15~0.70Mo，with 80×10-6～120×10-6N);and with same hardness value the relative wearing resistance of modified Cr5W steel increased by 50% as compared with that of Cr5 steel. |
