What is the Stainless Steel Passivation Process & why is it done? The Stainless Steel Passivation Process helps to improve the corrosion resistance of stainless steel parts by removing ferrous contaminants like free iron from their surface, restoring them to their original corrosion specifications. After a stainless steel part has been made or fabricated, it is necessary to undergo the process of passivation to improve the appearance & functionality of the domain. The manufacturing process can leave grease & other substances on the surface. Website: -https://www.rebaaus.com/passivation-for-stainless-steel/
