Abstract: In this paper, nonoriented silicon steel standards of EN, JIS, GB and ASTM were compared and analyzed. It is showed that, all types of standards in electromagnetic performance requirements are basically the same. Surface properties in ASTM standard are expressed in the most detailed. The mechanical properties requirements of the standards, except for ASTM, are basically the same.

Key words: nonoriented; silicon steel; standard analysis
