Passivation Services

Passivation of stainless steel is a process that removes free iron from the surface of stainless steel alloys, and at the same time promotes the formation of a thin oxide layer for protection. This process is what makes stainless steel ” corrosion resistant “. Free iron is the main contributor of surface corrosion on stainless steel parts. This is due to the cutting, forming, grinding, and welding processes when making the part. Particulates floating in the air or embedded in tooling equipment can pass the free iron to the surface of the stainless part and inhibit the corrosion process.

CEP can provide passivation services to ASTM A967, AMS2700, and QQ-P-35 specs.

We service many different industries including Water Sanitation, Dairy, Ag, Medical, Aerospace, Power Transmission / Distribution, and Petrol Chemical Industries.

We can process parts up to 44″L x 33″W x 27″H.
