摘　　要：以泵用材料ZGCr29Ni9Mo4N高强度钢和ZG07Cr19Ni9(SUS 304)γ不锈钢为对象,通过盐雾试验和电极电位测试及金相组织观察,对比研究了ZGCr29Ni9Mo4N高强度钢和SUS 304不锈钢的耐腐蚀性能和力学性能。结果表明,ZGCr29Ni9Mo4N高强度钢的力学性能和抗腐蚀性能均比SUS 304不锈钢显著提高。其中屈服强度提高了2倍多,硬度提高约1倍,抗腐蚀性能提高98%。Corrosion resistantance and mechanical properties of ZGCr29Ni9Mo4Nhigh-strength steel and ZG07Cr19Ni9（SUS 304）γstainless steel used for industrial pump were investigated comparatively with help of using salt spray test machine,electrode potential monitor and metallographic microscope.The results show that the mechanical properties and corrosion resistance of ZGCr29Ni9Mo4Nhigh-strength steel are superior greatly to those of SUS 304stainless steel,where the hardness,yield strength and corrosion resistance are increased by one time,more than two times and approximately 98%,respectively.
