標(biāo)準(zhǔn)簡介
1.1 This specification covers wrought iron-silicon (Fe-Si) steels that are generally used in the manufacture of electromechanical devices, such as relays and solenoids, requiring higher electrical resistivity, higher permeability, and lower coercivity and residual magnetism than provided by either carbon steels or soft magnetic low-carbon irons. The steels covered in this specification are:
| Steel Type | Nominal Composition |
|
|
|
| 1 | 1.1 % Si-Fe |
| 1F | 1.1 % Si-Fe free machining |
| 2 | 2.3 % Si-Fe |
| 2F |
