Although the higher nickel content of Stainless Steel Plate 309 provides marginal improvement with respect to chloride stress corrosion cracking (SCC) compared to the 18-8 stainless steels, Alloy Stainless Steel Plate 309 austenitic stainless steels remain susceptible to this form of attack.Certain applications specify the use of Alloy Stainless Steel Plate 309 where increased resistance to aqueous corrosion is needed. An example is service in concentrated nitric acid, where preferential attack of grain boundaries may occur.
