How an Acid Inhibitor Protects Steel

Here’s a visual (and dramatic) demonstration in our labs of how a hot acid bath will eat away at the steel your company works hard to produce. Use of one of our acid inhibitors (in this case, Activol® 1803) in the pickling process significantly reduces your surface pitting and metal loss to the acid.

Why Pickling Processes Require an Acid Inhibitor

The video below graphically demonstrates what happens to steel in hot HCl, once the scale is removed. (Remember that 90% of the scale is removed early on in the pickling process; the last tank or maybe tank and a half is necessary to remove the edge scale, which is the most difficult scale to remove.)

Therefore, for most of the process, the strip is actually descaled and is being dissolved in the acid in the form of iron chloride. The result is that the strip becomes overpickled, your yield is degraded, and the HCl is being consumed needlessly, thereby increasing your operating costs.

In this video, the metal used is descaled, grade 1011 steel in a bath of hydrochloric acid. The acid is eating away at the steel at a remarkable rate until the Activol® 1803 is added to protect the steel from the pickling process.
