Product Description


The extra-high tough steel for structural wear parts

350HBW steel is an abrasion-resistant plate with guaranteed impact toughness. With a nominal hardness of 350 HBW, it’s a good choice for structural wear parts like thick cutting edges, demolition tools and rippers.


Dimension Range

350HBW steel is available in thicknesses of 40 – 160 mm. 350HBW steel is available in widths up to 3350 mm and lengths up to 14630 mm. For thicknesses over 125 mm preferred width is 1650 mm. More detailed information on dimensions is provided in the dimension program.

(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 material thickness will not deviate more than ± 15 mm from that of the test specimen.

VANFORGE wear resistant steel is through-hardened. Minimum core hardness is 90 % of the guaranteed minimum surface hardness.

Delivery Conditions

The delivery condition is Quenched. The plates are delivered with sheared or thermally cut edges. Untrimmed edges after agreement.


Fabrication and Other Recommendations

Welding, bending and machining.

350HBW steel is not intend 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 450 ºC .

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.
