At 550 HBW and with a toughness close to Hardox 500
Hardox 550, with a nominal hardness of 550 HBW and toughness close to Hardox 500, increases wear life but not at the expense of crack integrity.
Hardox 550 is a Q & T martensitic wear plate for applications that demand high resistance to abrasion. Delivering a hardness of 550 Brinell, it offers a unique combination of excellent wear resistance, crack tolerance and workshop performance.
Hardox 550 comes in thicknesses of 10–50 mm (3/8–2") and widths up to 2800 mm (110"). Like all Hardox products, it is produced according to the AccuRollTech™ plate thickness guarantee. A fine-tuned chemical composition and a high-precision processing route give a typical impact toughness of 30 J/-40°C and a hardness accuracy guarantee of +/- 25 Brinell.
