LOCORE M43 is a cold-rolled, non-oriented electrical steel used primarily for alternating current (AC) and direct current (DC) motors, generators and transformers. It is produced either semiprocessed (the consumer anneals to produce the desired magnetic properties) or fully processed (the steel producer develops the magnetic properties to meet the maximum core loss values). This datasheet provides information on composition, physical properties, and elasticity. It also includes information on forming, heat treating, machining, and joining. Filing Code: SA-347. Producer or source: Republic Steel Corporation.
