研究了不同含碳量的高Ｃｒ、Ｍｎ合金在高温时的抗氧化、硫化腐蚀性及高温抗磨性，并在同条件下与常用的高Ｎｉ耐热钢的上述性能进行了对比．结论认为：（１）除抗氧化性外，几乎所有试验合金的高温抗磨性、抗硫化腐蚀性均高于高Ｎｉ耐热钢，但成本却比高Ｎｉ耐热钢低，（２）随试验合金的含碳量增加共晶碳化物数量增加，同时也提高了合金的氧化抗力，（３）含碳量在中等程度时合金的高温硫化腐蚀抗力处于低值，随腐蚀气氛中ＳＯ２分压增加，此值向低碳方向移动，（４）高温磨损过程中随温度提高基体强度下降，从而使碳化物对抗磨性的有益作用减弱。
The oxidation resistance, sulfidation corrosion resistance and high temperature abrasion resistance of high Cr and Mn alloys with different carbon contents were investigated. The results were compared with those of the conventional high Ni heat-resistant steels under the same conditions. The conclusions are as follows: (1) In addition to the oxidation resistance, almost all of the test alloys have higher high temperature wear resistance and anti-sulfur corrosion resistance than high Ni heat-resistant steel, but the cost is lower than that of high Ni heat resistant steel. (2) Increasing the carbon content of the alloy increases the amount of eutectic carbides and also increases the oxidation resistance of the alloy. (3) When the carbon content is moderate, the high temperature corrosion resistance of the alloy is at a low value. With the partial pressure of SO2 in the etching atmosphere Increase, this value to the low-carbon direction, (4) high temperature wear with the temperature increase in the matrix strength decreased, so that the beneficial effects of carbide on the wear resistance weakened.
