Tolerances

SSAB Domex is delivered with SSAB Domex tolerances, with improved guarantees compared to EN 10051:2010. More details are available at SSAB.com

Thickness

SSAB Domex thickness tolerances correspond to 2/3 of EN 10051:2010 as default value. After special agreement, tolerances down to 1/3 of EN 10051:2010 can be delivered for certain products and dimensions.

Length and Width

SSAB Domex tolerances for width and length are according to SSAB standard and offer narrower width and length tolerances compared to EN 10051:2010.

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.

Shape

SSAB Domex is delivered with shape tolerances according to EN 10051:2010. Tighter tolerances are available on request.

Flatness

SSAB Domex tolerances correspond to SSAB Flatness Guarantees Class A.

SSAB Domex tolerances guarantee a maximum flatness deviation of 3 mm/m in addition to the EN 10051:2010 flatness requirements.

Flatness guarantees only apply for cut to length sheets.

Surface Properties

Delivery Conditions

Thermomechanically rolled.

Surface and edge condition

SSAB Domex MC products are available with non-pickled or pickled surface with mill or cut edge.

Fabrication and Other Recommendations

SSAB Domex MC are cold forming steels not suited for heat treatments at temperatures above 580°C, since the material then may 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.

For information concerning fabrication, see SSAB’s brochures on www.ssab.com or consult Tech Support, [email protected].

Appropriate health and safety precautions must be taken when bending, welding, cutting, grinding or otherwise working on the product.
