Duroxite

Duroxite™-Taking Durability to the Extreme

Duroxite overlay products from Hardox Wearparts can add weeks, months, or even years of trouble-free operations to your most extreme wear situations.

It is comprised of abrasion-resistant materials deposited on top of mild steel or Hardox® wear plate to create an extremely wear-resistant compound material. An optimal carbide composition ensures homogenous bonding between the base metal and overlay, adding to Duroxite's high wear resistance and long service life.

Duroxite is manufactured by SSAB and is built on the company's extensive metallurgical knowledge in the wear arena.

Duroxite overlay works especially well in sliding wear environments where small and hard materials, such as coal with high quartz content, are processed. It can withstand different types of wear, such as abrasion, heat, metal-to-metal, and erosion wear.

Duroxite Fights Wear, Guaranteed

Duroxite comes with guarantees that are unique for the overlay market. Duroxite overlay products are delivered with an overlay thickness guaranteed within +10%.

When you order ¼” overlay on ¼” base plate, you are guaranteed an overlay thickness of ¼” within +10%. This is consistent throughout the plate and from plate to plate.

Further, consistent wear properties are guaranteed throughout the plate down to 75% of the overlay thickness as opposed to just the surface of the overlay. The remaining 25% of the overlay is the transition layer necessary to maintain good bonding to the base plate.

Duroxite in Fabrication

Duroxite welding Duroxite is designed to be hard without giving you a hard time in the workshop. No special equipment is needed to install Duroxite. Welding, bolting, and stud welding are the common methods for installing Duroxite wear parts or overlay plates onto your equipment. For more information on installation, see the Duroxite brochure.

One of Duroxite’s key benefits is its excellent formability due to a staggered cracking pattern on the overlay surface. This simplifies the bending of the plate and ensures a smooth flow of the processed materials.

Proven Performance

Duroxite is tough on wear wherever it is applied. It is the natural choice for industries active in mining, energy, quarries, cement production, and many other areas where abrasive materials require extremely hard surfaces. Here are some examples from different industries where our customers have seen extreme benefits from using Duroxite:

Gold mine, asphalt examples, plus the other applications from the previous brochure using the format in the brochure with photo and Industry, Application, Wear part, Purpose, Type of wear, and Benefit.

DUROXITE- Overview

The ultimate Duroxite product for your application depends on the material - whether rock, sand, gravel, or other substance—striking or sliding along the surface of your wear part. It also depends on the angle and speed of impact, as well as the operating temperature. Below is an overview of the Duroxite product line.
