90% to 100% commercial concentrated sulfuric acid.

The central principle is that carbon steel performs well in this service because a protective, insoluble iron-sulfate film forms on its surface when in contact with the acid. However, the standard's value comes from its detailed advice on the many factors that can disrupt this film and lead to rapid corrosion. Result: leak occurs two weeks later at the repair joint
