摘要
通过研制５２号合金与１３７号合金常温和高温硬度对比测试以及金相组织的对比分析，证明了５２号合金是比较理想的作为阀门密封面高温耐磨堆焊的合金材料．用它来代替目前普遍使用的钴铬钨贵重合金，具有较高的经济效益．
This article determines the hardness in atmospheric temperature and high temperature for the valve seal. It has ben proved that it has considerable economic significance to substitute number 52 alloy for Co-Cr-W alloy.
