Products Features
Name:Cold rolled non oriented electrical steel
Excellent electromagnetic properties
First class equipment, leading manufacturing process and strict management ensure the excellent and stable electromagnetic properties of Baosteel non-oriented electrical steel.
Excellent processing performance
High accuracy dimension and excellent mechanical property are convenient for the users to slit, punch and laminate.
Preeminent dimensional accuracy
Leading equipment and manufacturing technology ensure the good shape, smooth surface, uniform thickness, small transverse thickness deviation and high lamination factor.
Excellent surface coating properties
Baosteel non-oriented electrical steel has uniform surface coating with good adhesion, which can prevent peeling off coating during processing. The interlaminar insulation property is good.
More width options
The width of Baosteel non-oriented electrical steel is 700-1260mm, and users can choose from them to improve material utilization.
B Initial of Baosteel
Thickness digit 100 times the nominal thickness, in millimeters
Steel grade type character Character of steel grade type, such as:
