The magnetic properties are fully developed in as-delivered condition, and it is no longer necessary to anneal the material after punching.

Reference standard EN 10106 pertains to sheets and strips of cold-rolled non-grain oriented electrical steel in fully processed condition with a nominal thickness of 0.35 mm, 0.50 mm, 0.65 mm and 1.00 mm. The standard features general requirements for magnetic and geometric properties as well as tolerances, technological properties and test conditions.

Semi-processed electrical steel must be annealed at the customer in order to achieve specific electromagnetic properties.

Reference standard EN 10341 pertains to sheets and strips of unalloyed and alloyed non-grain oriented electrical steel in semi-processed condition with a nominal thickness of 0.50 mm, 0.65 mm and 1.00 mm. The standard features general requirements for magnetic and geometric properties as well as tolerances, technological properties and test conditions.
