耐硫酸泵用钢的选材研究

Material selection study of steels for sulphuric acid re-sistant pumps.

本文针对６０％Ｈ＿２ＳＯ＿４，温度为６０℃的苛刻介质条件，对７种铸造不锈钢进行了选材研究。通过均匀腐蚀、晶间腐蚀和电化学腐蚀试验结果表明，除３１６不锈钢外，其余各试验钢均具有良好的抗硫酸腐蚀性能，可根据生产中用户的要求选择使用。

material selection study of 7 cast stainless steelswas conducted for 60%H_2SO_4 medium at 60℃,The resultshowed that all test steels except for 316 stainless steelpossessed a high sulphuric acid corrosiun resistancethrough tests of uniform corrosion,intergranular corrosion,and electrochemical corrosion。Users should choosethem properly in production.
