| Abstract: | After a short period of service,two 316 stainless steel heat exchangers of the chemical feedwater system in a power plant were corroded.Through analyzing the operating conditions,crack characters,corrosion products and chemical composition of the material,it was concluded that the failure was caused by stress corrosion cracking(SCC).Some prevention measures were presented. |
