1.1 This specification covers cold-rolled carbon sheet steel used for magnetic applications. These products, commonly called "cold-rolled magnetic lamination steel" (CRML) are usually intended for applications in which the stamped laminations or assembled core structures for electrical equipment are annealed to develop the desired core loss and permeability characteristics.
1.2 By using appropriate lamination annealing practices, the user can optimize magnetic properties for the various types.
1.3 Non-guaranteed core-loss types, usually made to controlled chemical compositions, are available but are not covered by this specification.
1.4 Higher quality core-loss types are made to controlled chemical compositions and are usually given a critical reduction on a temper-mill to yield specified magnetic properties after a suitable lamination anneal. These products, typically called semiprocessed lamination steel, are classified by the ASTM Code Letter D in accordance with Practice A 664.
1.5 The values stated in customary (cgs-emu and inch-pound) units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units which are provided for information only and are not considered standard.
