硫酸泵用合金耐蚀性研究

Corrosion Tests of Alloys for Sulphuric Acid Pump

对九种耐硫酸泵用合金进行均匀腐蚀、晶间腐蚀、点腐蚀实验研究。结果表明，除３１６Ｌ不锈钢外，其余试验钢在特定介质条件下均具有良好的耐蚀性。

The corrosion tests on 9 alloys for H2SO4 pump were carried out in 20% and 50% H2SO4 at 60C to examine their resistance to uniform corrosion, intergranular corrosion and pitting. All alloys tested, except 316L, had excellent resistance.
