Tolerances

Thickness

SSAB Domex ML products are delivered with tolerances that correspond to ¾ of EN 10029:2011 Class A as default value.

Length and Width

Width tolerances -0/+4-10mm depending on the thickness. Length tolerances -0/+15-25mm depending on length.

Shape

According to EN 10029.

Flatness

Maximum flatness deviation 6 mm/m.

Surface Properties

Delivery Conditions

Thermomechanically rolled (M).

Fabrication and Other Recommendations

Minimum inner bending radius is 1.0 x t transverse to the rolling direction and 1.5 x t longitudinal to the rolling direction up to max 20mm in thickness.
