Corrosion Behaviour of Mild Steel in Sulphuric Acid

The corrosion of steel is the most common form of corrosion especially in acid solution. Sulphuric acid is also an important mineral acid with many uses in the same systems and leads the researchers to the study of the effect of the corrosion inhibitors 1–4 .

Corrosion resistance of duplex stainless steels

The prevention of corrosion is assumed to be suitable if the attack rate is lower than 0.1 mm per year. Duplex steel grades contain large magnitude of chromium that enables them to offer good corrosion resistance in the different environments. Sulfuric acid.

The corrosion rate of in sulfuric acid is negligible in any concentration from 0 to 99 up to a temperature of at least 150°C. In sulfuric acid at temperatures above 150°C the corrosion rate will have to be considered but the corrosion rate in high temperature sulfuric acid is magnitudes lower than the corrosion rates of Hastelloy titanium and zirconium.

Dec 31 2006 · Summary Monel is not recommended for handling sulphuric acid concentrations above 50 by weight. So I would not consider Monel period. If your specified concentrations are what you state 20Cb-3 would be even a better selection in comparison to 316L at least for the discharge piping because of fluid velocity effects on corrosion resistance.

Corrosion resistance. Pressureless sintered silicon carbide is almost universally corrosion-resistant. It resists against all common acids (e.g. hydrochloric acid sulfuric acid hydrobromic acid and hydrofluoric acid) bases (e.g. amines potash and caustic soda) all solvents and oxidizing media (e.g. nitric acid).
