                  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.
