Annotation of standard text ASTM A677-16(2023) :
This specification covers the standard requirements for flat-rolled nonoriented fully processed electrical steel intended primarily for commercial power frequency applications in magnetic devices. These electrical steels are low-carbon, silicon iron, or silicon-aluminum-iron alloys that may be made by basic-oxygen, electric-furnace, or other steelmaking practice. Desirable core-loss and permeability characteristics are developed during mill processing, so additional heat treatment is usually not required. The grades contained in this specification have thicknesses of 0.014 in. (0. 36 mm), 0.0185 in. (0.47 mm) and 0.0250 in. (0.64 mm). For a given thickness there are from 7 to 9 types based on the maximum value of core loss measured at 60 Hz and 15 kG (1.5 T) using the Epstein test method. Test methods to determine the required magnetic and mechanical properties are specified. Other typical magnetic and physical properties are listed for reference.
