摘要
针对温度为６０℃的盐酸复合介质环境，研制了一种新型高合金不锈钢。采用金相显微镜、ｘ射线衍射和电子探针等显微分析手段，观察与分析了新型钢的金相组织，并采用多种腐蚀试验方法研究了该种钢的腐蚀行为。试验结果表明，新型高合金不锈钢在１１５０℃经两小时水冷固溶化处理后，能获得良好的耐均匀腐蚀性能、抗晶间腐蚀能力和抗点蚀性能，并具有较好的铸造性能。
In the light of the corrosion resistance against chlorhydric acid complex medium at 60℃, a new high-alloy stainless steel is developed. The microstructure of the steel is analyzed by means of metallurgical microscope, x-ray diffractometer and electronic probe , and corrosion tests for the steel are made by several methods. The result of the tests shows that, after water cooled solution heat treatment for two hours at 1150℃, the new steel obtains good uniform corrosion-, intererystalline corrosion- and pitting corrosion-resistances and has good castability.
