Hardox 400 bars The all-round abrasion-resistant steel as round bar Hardox round bars are versatile, ready-to-use, abrasion-resistant steels that combine high toughness, good bendability and good weldability. Hardox round bars come in diameters between 40 and 100 mm and lengths up to 5000 mm and feature the same guaranteed properties as the wear plate. Delivered quenched and tempered to high tensile strength and hardness levels, Hardox round bars represent entirely new possibilities for stronger and lighter product design. They also help optimize workshop procedures such as machining, welding and polishing. Mechanical Properties Bar Diameter (mm) Hardness 1) (HBW) Typical Yield strength (MPa) 40.0 - 100.0 370 - 430 1000 - 1100 1) Bar hardness is measured on a milled surface, with indents positioned as impact test according to EN 10 083. Hardox is through-hardened. Minimum core hardness is 90 % of the guaranteed minimum surface hardness. Impact Properties Grade Longitudinal test, typical Impact energy, Charpy V 10 x10 mm test specimen Longitudinal test, guaranteed impact energy, Charpy V 10x10 mm test specimen Hardox 400 Bar 45J / -40°C Min. 27 J / -40°C Tolerances Tolerances More details are given in EN 10 060.
