Cold rolled pole sheets, also called tensile steel, are graded according to the 0.2% proof stress. Minimum values of tensile strength and elongation are defined as is magnetic polarization at field strength of 15,000 AT/m
Hot rolled material is carefully selected and processed according to a production technology related to the grades, enabling us to guarantee minimum values for our PowerCore® grades. PowerCore® grades are preferred for use in the poles of large high speed machines for poles and rims.
PowerCore® grades in thickness of <1.0mm can also be delivered with C6W insulation for better surface resistivity.
Dimensions, tolerance and geometric deviations are confirmed for PowerCore® grades according to specification IEC 404-8-5:1998.
