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.

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.
