Standard Specification for Nonoriented Electrical Steel Fully Processed Types
|Publication Date:||10 December 1999|
|ICS Code (Flat steel products and semi-products):||77.140.50|
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 purchaser is usually not necessary.
These nonoriented fully processed electrical steels are low-carbon, silicon-iron, or silicon-aluminum-iro
The values stated in either customary (cgs-emu and inch-pound) units or SI units are to be regarded separately as standard. The SI units are shown in brackets. The values stated in each system are not exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in nonconformance to this specification.
