ATI Steel Grain-Oriented Electrical Steel (Grade M-2) 数据表

Nominal thickness: 0.007in (0.18mm)

ATI Allegheny Ludlum Grain-Oriented Electrical Steel (GOES) is processed under carefully controlled conditions to develop optimum magnetic characteristics in the rolling direction. GOES develops low core losses at high inductions when used as core material in designs with the flux path parallel to the rolling direction. These low losses at high inductions are attained with low exciting currents because of the excellent high induction permeability of GOES. In addition, the normal operating inductions for GOES are sufficiently below the magnetic saturation of the material to allow a comfortable margin of safety in most designs. Processing of GOES is carefully controlled in order to achieve a very high stacking factor for the core material. This stacking factor often exceeds 95 percent of the theoretical maximum. The high usable magnetic induction of GOES, along with the high stacking factor, allow compact core designs requiring the minimum amount of material to be used in the windings surrounding the core. This contributes to low losses, not only in the core (no load losses), but also allows for minimum load losses or winding losses in the transformer.

ATI Allegheny Ludlum GOES also offers low manufacturing costs for transformer cores. GOES may be processed into conventional core designs and is available in a wide variety of widths ranging from 3 inches to 34 inches (7.6 cm to 86.4 cm). GOES can be formed by conventional methods. Slitting, cutting to length, winding, and stacking may all be accomplished using conventional core processing. Stress relief annealing, where required, can also be accomplished using conventional techniques.
