¹⁾ Brinell hardness, HBW, according to EN ISO 6506-1, on a milled surface 0.5 – 3 mm below surface. At least one test specimen per heat and 40 tons. The nominal thickness of supplied plates will not deviate more than +/- 15 mm from the thickness of the test specimen used for hardness testing. For sheet the Brinell hardness test is according to EN ISO 6506-1 on each heat treatment individual/coil. Hardness is measured on a milled surface 0.3 - 2 mm below surface.

Hardox^® wear plate is through-hardened. Minimum core hardness is 90 % of the guaranteed minimum surface hardness.

¹⁾ Impact testing is performed on thicknesses ≥ 6 mm for plate and ≥ 3 mm for sheet. For thicknesses between 3 and 11.9 mm, sub-size Charpy V-specimens are used. The specified minimum value is proportional to the cross-sectional area of the test specimen, compared to a full-size specimen (10 x 10 mm). Impact testing according to ISO EN 148 per heat and thickness group. Average of three tests

Thickness

Tolerances according to Hardox® Thickness Guarantee. Hardox® Guarantees meets the requirements of EN 10029 Class A for plate, but offers more narrow tolerances. For sheets the guarantees meets the requirements of 1/2 EN 10051.

Length and Width

According to SSAB’s dimension program. For plate, the tolerances are according to SSAB´s mill edge standard or tolerances that conform to EN 10 029. Tolerances conform to EN 10 051 for sheet, tighter tolerances available on request.

Shape

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

Flatness

Tolerances according to Hardox® Flatness Guarantees Class D for plate, which are more restrictive than EN 10 029. For sheet, the tolerances are according to Hardox® Flatness Guarantees Class A, that offer narrower tolerances compared to EN 10 051.

Surface Properties

According to EN 10163-2 Class A, Subclass 1.

Delivery Conditions

The delivery condition is Q or QT (Quenched or Quenched and Tempered). Plates are delivered with sheared or thermally cut edges and thicknesses over 80 mm are delivered with mill edge as standard. Sheets are delivered with an as-rolled surface and mill edge as standard.

Delivery requirements can be found in SSAB’s brochure Hardox® Guarantees or www.ssab.com.

Recommendations can be found in SSAB’s brochures at www.hardox.com or consult Tech Support, [email protected].

Bendability for plate is according to Hardox® Bending Guarantees Class G. For sheet, the bendability is according to Hardox® Bending Guarantees Class D.

Hardox® wear plate is not intended for further heat treatment. It has obtained its mechanical properties by quenching and when necessary by means of subsequent tempering. The properties of the delivery condition cannot be retained after exposure to temperatures in excess of 250ºC .

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.
