Sulfur corrosion stainless steel
Web24 Apr 2024 · By Samuel Markings. Sulphur dioxide, SO2, is a colorless gas that is toxic to human beings. It is produced both naturally by volcano's and by combustion of car gasoline. In its pure form, sulphur dioxide does not react strongly with metal alloys such as steel. However, in the presence of defects and water, sulphur dioxide can be highly corrosive. Web28 May 2024 · Stainless steel casting is the special steel casting type used primarily because of their corrosion resistance. All stainless steels casting grades contain a minimum percentage of 10.5% chromium. Chromium is always the deciding factor, although other elements, particularly nickel and molybdenum, are added to improve corrosion resistance …
