Astro Pak has been performing Picking and Passivation for nearly 60 years. We perform pickling of metallic surfaces to remove corrosion and weld damage from steam, heat and other corrosive environments. The pickling process prepares damaged stainless steel surfaces for proper passivation resulting in improved corrosion resistance. Our pickling process is a non-selective surface treatment that removes oxidation from stainless steel on heavily corroded surfaces. It is also used for nickel alloy or super-austenitic post weld preparation and embedded iron contamination.
In addition to Pickling and Passivation, Astro Pak offers a range of Surface Treatment including Electroplishing and Electropolishing. We also offer Media Blasting services, including Dry Ice and Bead Blasting.
