What is K-2?

A unique product for fumeless Pickling and Passivation for Surface Finishing on Stainless Steel and its alloys.


What is Pickling & Passivation?



Pickling is the removal of defects and also the inherent or thickened oxide film from the surface of the stainless steel.



Passivation is the chemical treatment of stainless steel with a mild oxidant (or acid), such as K-2 Passivation, with the purpose of removing free iron from the surface and speed up the process of forming a protective/passive layer. Passivation is a must after every pickling process.
