摘　　要：用MARS循环腐蚀回路对304NG不锈钢进行了1500h的循环水腐蚀考验,对均匀腐蚀速率进行了定量评估。试验结果表明:在模拟核反应堆一回路循环水条件下,304NG控氮不锈钢板材、锻件的均匀腐蚀速率为1.40mg/(dm2ˇ30d)和1.91mg/dm2(dm2ˇ30d),0Cr18Ni10Ti不锈钢板材、锻件的均匀腐蚀速率为4.44mg/(dm2ˇ30d)和4.65mg/(dm2ˇ30d),304NG控氮不锈钢的均匀腐蚀速率低于0Cr18Ni10Ti不锈钢。The circulating water corrosion test of 304NG stainless steel has been performed in the MARS loop for 1500h.The quantitative estimation for general corrosion rate of the 304NG stainless steel is given. The test result showed that the general corrosion rate of 304NG stainless steel is 1.40mg（dm^2·30d）（for plate） and 1.91mg/（dm^2·30d） （for forging） under the simulation primary circulating water environment of nuclear reactor. For 0Cr18Ni10Ti, it is 4.44mg/（dm^2·30d） and 4.65mg/（dm^2·30d）, respectively. The general corrosion rate of 304NG is lower than that of 0Cr18Ni10Ti under the simulation primary circulating water environment of nuclear reactor.
