机译:As I understand it, the passive film that protects stainless steel from corrosion is chromium oxide. I also understand that the heat tint on a weld surface and heat-affected zone (HAZ) is chromium oxide. If both my understandings are correct, then why is it often recommended, or even required, to remove the heat tint on any weld surface and HAZ? Are we wasting a lot of money cleaning stainless steel welds?
