Regarding the selection of steel materials resistant to dew point corrosion, which of the following materials is more effective against dew point corrosion, and why?
Thread Content
As the title suggests: Dew point corrosion mainly affects the flue gas from heating furnaces. In an environment with water vapor, the corrosion caused by hydrogen sulfide is also a concern. Under the same flue gas conditions, which material – carbon steel, stainless steel, grade 20 steel, or ND steel – is most resistant to dew point corrosion? Why?
In terms of economic efficiency, DN steel is better than stainless steel. As for why, you need to study the chemical elements just mentioned and their properties.
