Thanks to continuous improvements to manufacturing processes, all powercore® grades display a very flat strip shape. However, owing to physical conditions during rolling, thickness variations over strip width can only be reduced to a limited extent.
|Thickness deviations||Unit||NOMINAL THICKNESS inm mm|
|Max. deviation from nominal thickness||%||±8||±6||±5||±5|
|Max. thickness variation parallel to rolling direction within one sheet or strip with a length of 1 m||%||6||4||4||4|
|Max. variation of thickness transverse to rolling direction at a minimum distance of 30 mm from the edge||mm||0,02||0,02||0,03||0,03|
