PICKLE & PASSIVATE
Pickling is used as part of the acid cleaning process. This part of the process conditions the surface of the metal and loosens scale for easier removal.
Passivation creates a surface to eliminate contamination and prevent rust. Alloys Cleaning uses this process on stainless steel parts and castings, but not for steel.
Note: Contact with iron-based tooling after this process can cause the surface to rust.
