Mill scale is a steelmaking byproduct from the rolling mill in the steel hot rolling process. Mill scale contains both iron in elemental form and three types of iron oxides: Wustite (FeO), ematite (αH Fe 2. O. 3) and Magnetite (Fe 3O 4). The chemical composition of mill scale varies according to the type of steel produced and the process used.
Dec 12, 2010· Worked on a 100 year old building today. steel contractor is welding A36 doubler plates to existing steel girders. part of the doubler plate welds to an existing baseplate that sits atop a 4'' thick granite ledger.
