Standard Specification for Nonoriented Electrical Steel, Semiprocessed Types
N A683
Annotation
This specification covers the detailed requirements to which flat-rolled, nonoriented semiprocessed 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 through heat treatment by the user.
These nonoriented, semiprocessed electrical steels are low carbon, silicon-iron or silicon-aluminum-iron alloys containing up to about 2.5 % silicon and less than 1 % 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.
