Passivation of 416 stainless steel

WebPassivation involves creation of an outer layer of shield material that is applied as a microcoating, created by chemical reaction with the base material, or allowed to build by spontaneous oxidationin the air. WebIt is recommended that finished parts machined from stainless steel be passivated for optimum corrosion resistance. Free-machining types are prone to dulling and discoloration in passivating treatments. It is important that correct procedures be followed when passivation is specified. The recommended treatment for CRUCIBLE 416R is shown below:

WebA proper stainless steel passivation test consists of swabbing the part with a copper sulfate/sulfuric acid solution, maintaining wetness for six minutes and observing whether there is any plating of copper. As an alternative, the part may be immersed in the solution for six minutes. Copper plating occurs if iron is dissolved. Web2 Sep 2024 · Passivation of stainless steel is a chemical process to make it unreactive to moisture and oxygen, the primary substances that cause it to rust. The passivation process achieves this by creating a very thin layer (a few atoms wide) of Chromium Oxide (2Cr2O3) on the stainless steel’s exposed surface.
