Abstract

Abstract

The stress corrosion cracking (SCC) behaviour of low alloy steel in nitrate aqueous solution was investigated. The effect of temperature, medium concentration and potential on various corrosion types and thier intensities was determined. The temperature-concentration-potential SCC diagram was established. The down critical potential and sensibility zone of SCC was ascertained. The applicability of cathcdic protection was discussed.
