delstar› Metal PicklingThe pickling process is used to remove a thin layer of metal off of the stainless steel part. This is different from the descaling process, which removes visibly thick oxide scale from the stainless steel part. Our pickling solutions for stainless steel are mixtures of nitric acid and hydrofluoric acid.[PDF]
Pickling and Passivating Stainless Steel
from the surface of the stainless steel. Mixtures of nitric and hydrofluoric acids are usually used for pickling stainless steels. Pickling is the process used to remove weld heat tinted layers from the surface of stainless steel fabrications, where the steel’s surface chromium level has been reduced. PICKLING AND PASSIVATING STAINLESS STEEL 2.
Passivation vs. Pickling - Chemical Passivation & Metal ...
Metal Pickling. Pickling is intended to dissolve any existing oxidation, scale and weld oxides, and is capable of etching the base material.It utilizes more aggressive acids than those used in passivation. Metal pickling is most often used to remove the real world effects of handling, forming and fabrication.

Pickling & Passivation - Astro Pak
Pickling steel is the process of applying an acid solution to remove heat affected zones along with the underlying chromium reduced layer from the stainless steel. Pickled steel is free from surface carbon steel contamination and embedded iron particles.[PDF]
Electropolishing Stainless Steels
Pickling Pickling removes oxides specifically heat tint (from welding) and other discolourations or corrosion products. It creates a clean metallic surface that provides the conditions necessary for the natural self-passivation of stainless steel to take place. Typical compo-sitions involve nitric acid and hydrofluoric acid.
