2.2 Smelting method
The alloy is smelted in a vacuum induction furnace. Other smelting methods that meet the requirements of this standard may also be used, but this should be noted in the quality certificate.
2.3 Delivery status
The alloy strip is delivered without heat treatment.
2.4 Magnetic properties
The magnetic properties of the alloy sample shall comply with the provisions of Table 2. The magnetic properties of 1J30, 1J31 and 1J32 alloys are tested in the annealed state. The magnetic properties of 1J33 and 1J38 alloys are tested in the cold rolled state, and are also allowed to be tested in the annealed state.
