2016年12月27日 · 1.1 This specification covers the detailed requirements to which flat-rolled nonoriented fully processed electrical steel shall conform. 1.2 This steel is produced to specified maximum core-loss values and is intended primarily for commercial power frequency (50 and 60 Hz) applications in magnetic devices.

Look to Sko-Die for valuable information regarding non-oriented electrical steel fully processed (FP) ASTM A677.

1.2 This steel is produced to specified maximum core-loss values and is intended primarily for commercial power frequency (50 Hz and 60 Hz) applications in magnetic devices. Desirable core-loss and permeability characteristics are developed during mill processing, so additional heat treatment by the user is usually not necessary.
