Standard Specification for Nonoriented Electrical Steel Fully Processed Types
N A677
Annotation
This specification covers the detailed requirements to which flat-rolled nonoriented fully processed electrical steel shall conform.
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. Desirable core-loss and permeability characteristics are developed during mill processing, so additional heat treatment by the user is usually not necessary.
These nonoriented fully processed electrical steels are low-carbon, silicon-iron, or silicon-aluminum-iron alloys containing up to about 3.5 % silicon and a small amount of aluminum.
The values stated in SI units are to be regarded as standard. The values given in parentheses are mathematical conversions to customary (cgs-emu and inch-pound) units which are provided for information only and are not considered standard.
