| 摘 要： | 研究了碳、铌含量对ASME S30432钢晶间腐蚀性能的影响.结果表明:当碳含量在0.058%～0.110%变化时,随碳含量增加该钢的晶间腐蚀敏感性增加,易发生晶界腐蚀;铌含量由0.30%增加到0.70%对抗晶间腐蚀性能有改善,含碳量对晶间腐蚀的影响比铌明显;铌含量与碳含量的比值至少在5.8以上才可能对晶间腐蚀有抑制作用. |

| Abstract: | The influence of carbon content and niobium content on the intergranular corrosion of ASME S30432 austenitic heat resistant steel has been investigated. When the carbon content increases from 0. 058% to 0. 110%, the sensitivity of intergranular corrosion is improved, and intergranular corrosion easily happenes. Increase of niobium content from 0. 30% to 0. 70% benefites the intergranular corrosion resistance. Carbon content show much more effect on the intergranular corrosion than niobium content. When the ratio of niobium content to carbon content exceedes 5. 8 times, it could restrain intergranular corrosion. |
| Keywords: | ASME S30432 steel intergranular corrosion carbon content niobium content |
