    • A soft magnetic article is disclosed which is formed of an alloy consisting essentially of, in weight percent, about C 0.003 - 0.02, Mn 0.10 max., Si 0.10 max., P 0.01 max., S 0.003 max., Cr 0.1 max., Ni 0.2 max., Mo 0.1 max., Co 48 - 50, V 1.8 - 2.2, Nb 0.15 - 0.5, N - 0.004 max., O 0.006 max. with the balance essentially iron. The article is annealed at a temperature of not more than 740 DEG C (1364 DEG F) for not more than about 4 hours and provides a room temperature yield strength of at least about 620 MPa (90ksi) in the annealed condition. Among the disclosed embodiments of the annealed article according to this invention are a rotor and a stator for a rotating electrical machine such as a motor, generator, alternator or a magnetic bearing.
    • 公开了一种软磁体制品,其由基本上以重量百分比计,约C 0.003-0.02,Mn 0.10最大,Si 0.10最大值,P 0.01最大值,S 0.003最大值,Cr 0.1最大值, ,Ni 0.2最大,Mo 0.1最大值,Co 48-50,V 1.8 -2.2,Nb 0.15-0.5,N - 0.004最大,O 0.006最大。 平衡本质上是铁。 该物品在不高于740℃(1364°F)的温度下退火不超过约4小时,并且在退火条件下提供至少约620MPa(90ksi)的室温屈服强度。 在根据本发明的退火制品的所公开的实施例中,是用于诸如电动机,发电机,交流发电机或磁性轴承的旋转电机的转子和定子。
