Standard Specification for Nonoriented Electrical Steel Fully Processed Types

This specification covers the detailed requirements for flat-rolled nonoriented fully processed electrical steel intended primarily for commercial power frequency applications in magnetic devices. Desirable core-loss and permeability characteristics are developed during mill processing, so additional heat aatm is usually not necessary. The electrical steel shall conform to the specified magnetic 6a77 including: Close this window and log in.

Test methods to determine the magnetic and mechanical properties including Epstein test and bend test are detailed. Digital Transformation may be defined in a number of different ways by analysts or enterprise software vendors. The processing sequence for the electrical steel comprises hot-rolling, annealing, pickling, cold-rolling, and decarburizing annealing.
