ASTM A726-18 pdf free.Standard Specification for Cold-Rolled Magnetic Lamination Quality Steel, Semiprocessed Types.
1.1 This specification ctncrs told-rolled carbon sheet steel uscd for magnetic applications. Thcsc products. commonly called “cold-rolkd magnetic lamination steel” (CRMI.) are usually intended fur applications in which the stamped bminations or assembled core structures for electrical equipment are annealed to develop the desired core loss and permeability characteristics.
1.2 This steel is prodaced to masimum specific core-loss salucs hind is intended primarily hr commercial power Irequcncy (50- and 60-Hi) applications in magnetic devices. Specific core-loss and permeability characteristics in conformance with this specification are developed through heat treatment by the user.
1.3 Non-guaranteed core-loss types. usually made to contmllcd chemical compositions. arc availahic hut are not coyered by this specificabon.
1.4 Higher quality core-loss types are low carbon, siliconiron, or silicon-aluminum-iron alloys containing up to about 2.5 q silicon and less than I % aluminum. These steels are usually given a critical reduction on a temper-mill to yield specified magnetic properties after a suitable lamination anneal. These products, typically called serniprocessed magnetic lamination steel, are cbssitied by the ASTM Code Letter D in accordance with Practice A6M.
1.5 The values statcd in SI units are to he regarded as standard. 11w salues gisen in parentheses arc rnatheniatical cons ersions to customary (cgs-emu and inch-pound) Units hich are provided for information only and are not considered standard.
1.6 This siundani does not purport to address all of she safety concerns. if any, associated with its use.
