摘　　要：本文介绍了一种针对高温腐蚀工况的新型耐热钢TRG-ZA-10。传统的Cr-Ni奥氏体耐热钢,以ZG_(40)Cr_(25)Ni_(20)Si_2为代表,具有良好的高温抗氧化性能和热强性能,但在硫化物和氯化物浓度较高(尤其是氯化物)的高温工况中,其使用寿命急剧下降,不能满足使用要求,因此需要一款专门针对高温腐蚀工况的新型材料以解决该问题。Abstract： This paper introduces a new type of heat-resistant steel TRG-ZA-10 for high temperature corrosion conditions. The traditional Cr-Ni austenitic heat-resistant steel represented by ZG40Cr25Ni20Si2 has high temperature oxidation resistance and good thermal strength performance, but when at high temperature conditions with higher sulfides and chlorides （especially chlorides） concentration the service life of steel declines sharply, which was not able to meet the requirements. So a specialized new material using at high temperature corrosion condition is required to be developed to solve the problem.
