SSAB Domex is delivered with SSAB Domex tolerances, with improved guarantees compared to EN 10051. More details are available at SSAB.com
SSAB Domex thickness tolerances correspond to 2/3 of EN 10051 as default value. After special agreement, tolerances down to 1/3 of EN 10051 can be delivered for certain products and dimensions.
SSAB Domex tolerances for width and length are according to SSAB standard and offer narrower width and length tolerances compared to EN 10051.
For coil and sheet with mill edge, the width tolerances are corresponding to -0/+20 mm.
For coil and sheet with cut edge, the width tolerances are corresponding to -0/+2 mm.
After special agreement, tighter tolerances can be delivered for certain products and dimensions. Length tolerances only apply for cut to length sheets.
SSAB Domex is delivered with shape tolerances according to EN 10051. Tighter tolerances are available on request.
SSAB Domex tolerances guarantee a maximum flatness deviation of 3 mm/m in addition to the EN 10051 flatness requirements.
Flatness guarantees only apply for cut to length sheets.
According to EN 10163-2 Class A, Subclass 3.
SSAB Domex MC are cold forming steels not suited for heat treatments at temperatures above 580°C, since the material may then lose its guaranteed properties.
SSAB Domex is well suited for all common thermal and mechanical cutting processes. SSAB Domex offers good cold forming properties. Welding can be performed, using all common methods and consumables.
