Dimensions and tolerances

Sheet thickness(mm) Thickness tolerance ± mm or % of the thickness Max.width(mm) Width tolerance(±)
1.00 +0.08 850 2.0
1.0-1.5 0.13 850 2.0
1.5-2.0 0.15 850 2.0
2.0-3.6 0.18 1000 2.0
3.6-50.0 5% 1000 2.0

The length tolerance for sheet length up to 2500mm is max. +5/-0 mm.
Flatness: max 4 % (measuring procedure on the basis of ASTM B386)
Density: ≥10.1g/cm³
Hardness Vickers: ≤250 HV
Appearance: The material will be of uniform quality, free from foreign matter, splits and fractures. Bed sheets (not trimmed) may have small edge cracks.
Surface defects are assessed in the frame of visual inspection.
Local surface defects can be removed by frinding within the specified thickness tolerance.
Surface quality: Pickled
