ASTM A677/A677M-99
Historical Standard: Standard Specification for Nonoriented Electrical Steel Fully Processed Types
ASTM A677/A677M
Scope
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. Desirable core loss and permeability characteristics are developed during mill processing, so additional heat treatment by the purchaser is usually not necessary.
1.3 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.
Note 1-A complete metric companion to Specification A677 has been developed, A677M; therefore no metric units are shown in this specification.
