Removing Mill Scale from Steel Surfaces

Identifying Mill Scale. Mill scale (often known simply as 'scale') refers to the thin, flaky texture that forms on the outer surface of hot-rolled iron oxides and metals. It is a by-product of manufacturing hot-rolled metal plates and sheets, occurring as the surface oxidizes during the heating, conditioning and hot rolling processes.Get price
