CORROSION OF 18/8 AUSTENITIC STEEL IN NITRIC ACID ENVIRONMENTS CONTAINING CHLORIDES

Technical Report ·
OSTI ID:4264960

The factors influencing the corrosion of 18/8 austenitic steel in nitric acid environinents containing chloride have been studied in laboratory tests. Selective attack occurs on steel surfaces in contact with condensate but not in bulk solution. Important controlling factors are temperature, free acidity, chloride concentration and dissolved oxygen. The interaction of these factors is complex. Tests involving the dissolutlon of a South African concentrate gave results similar to those in synthetic solutions of similar composition. The relevance of the findings to the problem of plant corrosion in the cascade dissolvers at Springfields is discussed. (auth)
