Emphasis on sulfuric acid dew point corrosion over hydrochloric acid | High-strength corrosion-resistant steel plate for flue gas S-TEN2

For hydrochloric acid dew point corrosion, S-TEN1 is considered, while S-TEN2 is used for sulfuric acid dew point corrosion and flue gas equipment requiring high strength. They are differentiated based on the corrosive environment and the required strength.

S-TEN2 is a corrosion-resistant steel plate for welded structures that has resistance to sulfuric acid dew point corrosion and strength equivalent to SM490A. While S-TEN1 is designed for sulfuric and hydrochloric acid dew point corrosion, S-TEN2 specifically targets sulfuric acid dew point corrosion. COR-TEN is a weather-resistant steel that forms a protective rust layer in the atmosphere, which differs in application from S-TEN2, intended for flue gas equipment where acids condense. 【Recommended for the following issues】 - Rapid corrosion of flue gas ducts - Need for both corrosion resistance and strength - Unclear differences from S-TEN1
