Sulfuric-acid Dew Point Corrosion-resistant Steel

    Grade: 09CrCuSb(ND Steel), S-TEN 1, S-TEN 2, etc.

Sulfuric-acid Dew Point Corrosion-resistant Steel is a corrosion resistant steel for sulfuric acid and hydrochloric acid dew-point corrosion-resistant steel, it has been widely used in flue gas treating equipment such as air preheaters, smoke stacks and ducts as a countermeasure for low temperature corrosion caused by sulfur oxides.

The steel also shows excellent corrosion resistance to the corrosion problem at waste incineration facilities, where hydrochloric acid dew corrosion resulting from lower-temperature waste gas, is anticipated.
