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.
