This specification covers the standard requirements for cold-rolled magnetic lamination quality steel that can be used for magnetic applications. The steels shall be made by the basic-oxygen or electric-furnace method and shall be processed by hot rolling, pickling, cold rolling, annealing, and temper rolling. Magnetic lamination steels shall have low-carbon contents and may have manganese, phosphorus, silicon, and aluminum additions to enhance punchability and to improve magnetic characteristics by increasing the electrical resistivity. A test method for alternating-current magnetic properties shall be performed, and shall conform to the limits of core loss and permeability values. The magnetic properties of these steels shall be optimized by annealing of the stamped laminations or assembled core structures. Materials shall also undergo mechanical tests to determine steel hardness which is dependent on chemical composition and mill processing. Finished products shall be marked by having the producer’s order number and material identification legibly shown on a tag attached to each coil or shipping unit.
