# Hydrochloric acid: Relationships

Source page: https://www.materialinsights.org/chemicals/hydrochloric_acid/links/

Every element and industry that Hydrochloric acid is linked to, and how. Each pair has its own card explaining the relationships between the two.

- [Steel](https://www.materialinsights.org/links/hydrochloric-acid-and-steel/): Steel mills use hydrochloric acid to pickle hot-rolled strip before cold rolling and coating, making steel one of the main outlets for an acid that is mostly a by-product of chlorine chemistry. Large mills regenerate up to 99.5% of their acid, so merchant demand comes mainly from smaller pickling lines. *(researched)*
