Sulfuric acid promotes general and localized corrosion of carbon steel. Carbon steel heat affected zones may experience severe corrosion. Acid concentration, temperature, alloy content and ____________ are critical factors affecting sulfuric acid corrosion.
Velocity is an important factor in the corrosion of carbon steel in sulfuric acid environments. The movement of the acid affects how the acid interacts with the steel surface, influencing both the rate and pattern of corrosion. Higher velocity can increase the rate at which the acid contacts the metal's surface, thus promoting more rapid corrosion.
Critical Factors of Sulufuric Acid Corrosion : - Acid concentration - Temperature - Alloy content - Velocity - Contamination, and - Presence of oxidizers.
