A special steel that boasts high hardness and toughness without heat treatment! Contributing to weight reduction and minimizing wear to extend service life, it is active in a wide range of fields!
HARDOX is manufactured and sold by the Swedish special steel manufacturer SSAB. The wear-resistant steel plate HARDOX is characterized by its high hardness without heat treatment, making it possible to minimize wear. It also has high toughness, allowing it to be bent and welded without cracking. In addition to plates, we also handle round bars and pipes with the same mechanical properties. As a new product, we have started handling the wear-resistant overlay steel plate DUROXITE, which is effective against sliding wear caused by powders and fine particles, which HARDOX was previously unsuitable for. 【Features】 ○ A cutting sales system tailored to customer needs, with five grades of HARDOX ranging from 400 to 600, available in various thicknesses and widths. ○ High strength and high hardness while allowing for various processing methods → Gas cutting, laser cutting, bending, machining, drilling, welding, etc. ○ Possibility of weight reduction with ultra-high strength that exceeds high-tensile steel. *For more details, please contact us or download the catalog.
