Stainless steel pipes rely on a very thin, strong, dense, and stable chromium-rich oxide film (protective film) formed on their surface to prevent further oxygen infiltration and oxidation, thus achieving their rust resistance. If this film is continuously damaged for some reason, oxygen atoms from
First: Causes of Alkali Reversion (White Rust, Black Spots)1. Principle of White Rust Formation on Galvanized Steel Sheets: When galvanized steel sheets are densely packed and placed in humid air, without free air flow across the surface, electrochemical corrosion of the zinc layer occurs, resulting
In the steel plate business, many people often encounter these types of products, and some are confused about the differences: Is pickling considered cold rolling or hot rolling? Is cold forming considered cold rolling or hot rolling? Are hard rolling and cold rolling the same? These are soul-search
