Both are non-oriented steel grades. More detailed information about these two types of steels can be found in The Metals Handbook. Many organizations around the world have adopted specifications to characterize and describe the various steel grades used for rotor laminations. Information on some of these specifications is also described below. Direct Experimental Observations on Concurrent Non-grain oriented electrical steel, with minor in-grain orientation gradients, was subjected to interrupted tensile deformations and concurrent microtexture, magnetic property and residual stress measurements. After the upper yield point, clear signatures of mechanical stress relief were observed. Changes in orientation gradients led to annihilation of low-angle (1 to 3 deg) boundaries.

We work with multiple steel sources to make certain we deliver our customers a consistent and uninterrupted supply of electrical steel. Non-Oriented Steel These are electrical steels in which the magnetic properties are uniform in any plane of the material. Electrical Steel Market Size, Industry Share and Growth The non-grain oriented electrical steel is used in applications such as motors and generators. Exhibition of one-directional magnetic properties by grain-oriented electrical steel differs from the non-grain oriented electrical steel which exhibits magnetic properties in all directions. Electrical Steel Market Size, Share Industry Analysis Electrical steel market is categorized into two types namely, grain-oriented and non-grain oriented. Grain oriented electrical steel is anticipated to be the fastest growing segment owing to its increasing demand from transformers cores used in transformers and large generators. It is an iron-silicon alloy with a silicon level of 3%.
specically oriented grain grew and consumed other new grains and the initial single crystal under the magnetic driving force [17, 18]. Recently, magnetically induced grain boundary migration was measured in specially grown pure zinc bicrystals [19, 20]. D. A. Molodov (&) C. Gu¨nster G.
