sulfuric acid compatibility with metalsPro-Blinds

Sulfuric AcidRolled Alloys Inc. Sulfuric acid is the most widely used corrosive in the world and is generally considered to be the most important industrial chemical. The corrosivity of sulfuric acid on steel and nickel alloys can vary significantly. Depending on acid concentration and the metal involved sulfuric acid can behave as either

Materials For Sulfuric Acid PipingCorrosion engineering

 · Diluted acid (2- 4 ) can be conveyed in with Alloy 20. 904L and 317L. 316L is marginal depending on the temperature. You should also consider non-metal piping for the dilute acid. CPVC and vinyl ester resin piping have very good resistance but need proper support too. RE Materials For Sulfuric Acid Piping. CdotS (Materials) 25 Feb 02 12 48.

Sulfuric Acid Corrosion H2SO4 Corrosion of Stainless Steel

 · Sulfuric Acid in concentrations between 10 and 90 is known to be especially corrosive. Common type specialty metals like e.g. titanium and Hastelloy c-276 will show rapid corrosion in sulfuric acid at temperature lower than 100 C. Very few materials including exotic metals like Zirconium and Tantalum materials can be applied above the sulfuric acid boiling point.
