WEBMill scale occurs in the steel production line, mainly during the hotrolling process. As steel is processed at temperatures above 1832°F (1000°C), the high heat causes the surface iron to react with oxygen in the air or water vapor, resulting in iron oxide formation. This layer forms as the outer surface of the steel cools, creating what we ...
