The extra-high tough steel for structural wear parts
Hardox® HiTuf 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.
1) Brinell hardness, HBW, according to EN ISO 6506-1, on a milled surface 0.5 – 3 mm below surface for plate. 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.
1) Impact testing according to ISO EN 148 per heat and thickness group. Average of three tests. Single value minimum 70% of specified average.
The steel is grain refined. *) Intentional alloying elements.
Tolerances according to Hardox® Thickness Guarantees.
