1) More detailed information on dimensions is provided from RaexSmart. Please contact your local sales representant for more information.

2) Brinell Hardness is measured, according to EN ISO 6506-1 on milled surface 0.3-3.0mm below surface. Hardness value is being announced in the material certificate.
Mechanical properties are tested in transverse direction and tabulated for information only and values are not shown in material certificate.

Tolerances

Thickness

Plates tolerances according to EN 10029 Class A, tighter tolerances upon agreement. Sheets tolerances according to EN 10051 Category A.

Length and Width

For plate tolerances according to EN 10029, tighter tolerances upon agreement. Sheets tolerances according to EN 10051.

Shape

Tolerances according to EN 10029 for plate and according to EN 10051 for sheet.

Flatness

For plate and sheet the flatness deviation is max 6 mm/m.

Surface Properties

According to EN 10163-2 Class A, Subclass 3.

Bending

Minimum inner bending radii for a 90° bend, t ≤ 20 mm are:

Sheets and plates, 3 x t (transverse) and 4 x t (longitudinal).

Delivery Conditions

The delivery condition is quenched. Sheets are available in as rolled surface condition with mill edge. Plates are available in as-rolled or shopprimed surface condition. Delivery requirements can be found in SSAB´s brochure at www.raexsteel.com.

Fabrication and Other Recommendations

Welding, bending and machining recommendations can be found in brochures at www.raexsteel.com or consult Tech Support.

Raex® AR is not intended for further heat treatment. Mechanical properties are achieved by quenching. The properties of the delivery condition cannot be retained after exposure to temperatures in excess of 250°C.

Appropriate health and safety precautions must be taken when welding, cutting, grinding or otherwise working on this product. Grinding, especially of primer coated plates, may produce dust with a high particle concentration.
