ASTM A677M-98a

Заменен
Standard Specification for Nonoriented Electrical Steel, Fully Processed Types (Metric) (Withdrawn 2000) — 5 стр.
Область применения

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 further heat treatment by the purchaser is not usually 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-This specification is the metric companion of Specification A677.
