Wide strip is slit into finished sizes in special slitters with cemented carbide tools, which give a very high edge quality and extremely close tolerances. After slitting, a corrosion-preventive oil is applied to the strip.
Width tolerances
+/- 0.020 mm (0.0008 in.) for widths up to 20 mm (0.787 in.)
+/- 0.035 mm for widths over 20 mm (0.787 mm)
The variation within a coil is max. +/- 0.010 mm (0.0004 in.).
