Encountering any or all of these contaminants can easily lead to localized corrosion or cause weld embrittlement and failure. We are using sulfuric acid to maintain the pH of cooling water at our plant. Weldments subjected to corrosive attack over a period of time may crack adjacent to welds if the residual stresses are not removed. General and localized corrosion, stress corrosion, corrosion fatigue. Corrosion associated with weldments. Water chemistry issues and control. Remedial measures to degradation problems. Preferential weldment corrosion (PWC) of carbon and low alloy steels used for pipelines and process piping systems in CO 2 -containing media has been observed increasingly in recent years. We are experiencing severe damage to the SS-316 material piping at the outlet of the sulfuric acid storage vessel. Certain magnesium alloys are subject to stress corrosion. 1 carbon steel materials must be performed per NACE Standard RP0472 "Methods and Controls to Prevent In-Service Environmental Cracking of Carbon Steel Weldments in Corrosive Petroleum Refining Environments. Irradiation-assisted stress corrosion cracking.
