摘　　要：介绍了耐浓硝酸介质腐蚀的新型低铬高硅铸造不锈钢的化学成分,着重研究了含镍量对其组织、冲击韧性与腐蚀行为的影响。试验结果表明,含有7％Ni的超低碳Cr13Ni7Si4Nb双相铸造不锈钢,在浓硝酸介质中具有优良的耐蚀性能,并具有良好的冲击韧性和铸造性能。The chemical composition of new type low chrome high silicon casting stainless steel resisted concentrated nitric acid corrosion was recommended. The influence of nickel content on its structure, impact flexibility, and corrosion behavior was researched emphatically. The testing results show that the super low carbon Crl3Ni7Si4Nb diphase casting stainless steel containing 7 % Ni has a good property of resisting corrosion in the concentrated nitric acid solution, and has good impact flexibility and casting property.

关 键 词：双相铸造不锈钢 腐蚀行为 冲击韧性 铸造性能
