摘　　要：采用实验室加速腐蚀实验对比研究316L、304不锈钢和20^#锅炉钢（记为20g）在模拟黄磷尾气腐蚀环境条件下的腐蚀性能。结果表明,316L不锈钢的耐蚀性要优于304不锈钢和20g,在250℃～300℃时304和316L不锈钢均发生酸蒸汽的露点腐蚀,且304不锈钢出现较为严重的孔蚀现象。The corrosion properties of 316L,304 stainless steel and 20^# boiler steel（20g） in a simulated corrosive atmosphere were investigated by means of accelerated corrosion test.The results show that corrosion rate of 316L was significantly lower than that of 304 and 20g in the simulated atmosphere.From temperature 250℃to 300℃,the acid dew point corrosion became serious.Cavities were observed in the surface of 304 after the dew point corrosion,at where occurred pitting corrosion.
