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 possesses high toughness, allowing for bending and welding 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, for which HARDOX was previously considered unsuitable. 【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.

Focusing on this property, we custom-manufacture special bolts for attaching and detaching liners and other components that are subjected to harsh operating environments, as well as bolts that require consideration of wear resistance. A company was experiencing significant issues with the installation bolts for the inner lining of a rod mill that crushes ore and metal rods, with about two bolts breaking each day. By using bolts made from HARDOX500, the breakage was dramatically reduced to just five bolts per year! Maintenance time was shortened, and operational efficiency significantly increased!! Our company's HARDOX500 bolts were featured in a magazine published by SSAB Swedish Steel, distributed worldwide. Moreover, we received a silver medal! *Bolts are crucial components used for joining parts, and their lifespan can be greatly affected by usage conditions, load states, and bolt shapes. Therefore, detailed discussions are necessary when placing an order.

Plates made from HARDOX wear-resistant steel not only possess excellent toughness and high strength, but also have outstanding weldability and workability. Moreover, they maintain high toughness and high hardness even at low temperatures of -40°C. 【Features】 ● High wear resistance, 25 times that of ordinary steel in the case of HX600 ● High hardness, Brinell hardness of 600 in the case of HX600 ● High strength, tensile strength of 2000 MPa in the case of HX600 ● High toughness, impact value of 20 J (-40°C) in the case of HX600 ● Uniform strength, hardness, and toughness throughout the core ● No need for buildup, heat treatment, or surface treatment ● Excellent weldability and workability ● Equipped with impact resistance and weld crack resistance even for use in cold regions ● Available in various grades, thicknesses, and applications ● Custom orders and made-to-order options available 【Applications】 ■ Fan plates for blowers and feeders ■ Various wear-resistant wear plates ■ Various base plates ■ Water impact plates ■ Plates for crushers ■ Side plates (with screw machining) ■ Grab bit keep plates ■ Anvils ■ Washer plates ■ Screw blade sides ■ Edges for snow removal machines in cold regions 【Content Note: For more details, please refer to the catalog.】

"STRENX" is a pre-hardened steel that has minimized residual stress to the extreme. It is a steel plate that combines high strength and high toughness, capable of withstanding impact and welding crack resistance even in cold environments at -40 degrees, while also possessing excellent bendability. 【Features】 - Excellent fracture resistance due to high impact toughness - Superior bendability and surface quality - Weldability that combines high strength and toughness - Unmatched consistency within the steel plate due to high precision For more details, please contact us or download the catalog.
