ASTM A683M - 91 Standard Specification for Nonoriented Electrical Steel, Semiprocessed Types [Metric] (Withdrawn 1999)

1. Scope

1.1 This specification covers the detailed requirements to which flat-rolled, nonoriented semiprocessed 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 by further heat treatment by the purchaser.

1.3 These nonoriented semiprocessed 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-This specification is the metric companion to Specification A683.
