ASTM A726-00 半成品类冷轧磁性迭片级钢标准规范

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 where 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 purchaser can optimize magnetic properties for the various types. 1.3 A non-guaranteed core-loss type is usually made to controlled chemical composition. However, magnetic properties are not guaranteed by the producer. 1.4 Higher quality core-loss types are made to controlled chemical composition and are usually given 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 Specification A664. 1.5 The values stated in inch-pound, cgs, and em units are to be regarded as standard. Note 1-A complete metric companion to Specification A726 has been developed-A726M; therefore, no metric equivalents are presented in this specification.

1.1 This practice covers the procedure for designating (within ASTM specifications) standard grades of flat-rolled electrical and lamination steels made to specified maximum values of core loss. It applies to magnetically soft irons and steel (low-carbon steels and alloys of iron with silicon, aluminum, etc.) where a core-loss measurement at a stated peak value of alternating induction and a stated frequency, such as 15 kG (1.5 T) and 60 Hz, is normally utilized to grade the material. It also applies when some other property is specified (or a different induction or frequency, or both) as the limiting characteristic, provided the material also meets all the requirements of the ASTM specification. 1.2 Individual specifications that are in conformity with this specification are A677, A677M, A683, A683M, A726, A726M, A840, A840M, A876, A876M. 1.3 This standard does not purport to address all of the safety problems, if any, associated with its use.

ASTM A804/A804M-99 在电源频率下用薄钢板型试样对材料交流磁特性的测试方法

1.1 These test methods cover the determination of specific core loss and peak permeability of single layers of sheet-type specimens tested with normal excitation at a frequency of 50 or 60 Hz. Note 1-These test methods have been applied only at the commercial power frequencies, 50 and 60 Hz, but with proper instrumentation and application of the principles of testing and calibration embodied in the test methods, they are believed to be adaptable to testing at frequencies ranging from 25 to 400 Hz. 1.2 These test methods employ calibration procedures that provide correlation with the 25-cm [250-mm] Epstein test. 1.3 The range of test inductions is governed by the properties of the test specimen and by the available instruments and other equipment components. Normally, nonoriented electrical steels can be tested over a range from 8 to 16 kG [0.8 to 1.6 T] for core loss. For oriented electrical steels, the normal range extends to 18 kG [1.8 T]. Maximum inductions in peak permeability testing are limited principally by heating of the magnetizing winding and tests are limited normally to a maximum a-c magnetizing force of about 150 Oe [12 000 A/m]. 1.4 These test methods cover two alternative procedures as follows: Test Method 1-Sections 6 to 12 Test Method 2-Sections 13 to 19
