The Latest in Overlay Technology

December 1, 2016

SSAB, manufacturer of Hardox wear plate, introduces Duroxite, an overlay comprised of abrasion-resistant materials deposited on top of mild steel or Hardox wear plate. The result is an extremely wear-resistant compound material. Use it for sliding-wear environments where small and hard materials are processed, such as coal with high quartz content. It also plays an important role as a wear-resistant material in high-temperature environments.

Says Gregoire Parenty, head of SSAB Services: “Duroxite is a natural choice for many industries, such as mining, cement production and handling, coal-fired power generation and similar applications.”

Duroxite comes with guarantees reportedly unique for the overlay market, including an overlay thickness guaranteed within ±10 percent—throughout the plate and from plate to plate. Further, consistent wear properties are guaranteed throughout the plate down to 75 percent of the overlay thickness, as opposed to just the surface of the overlay. The remaining 25 percent of overlay is the transition layer necessary to maintain good bonding to the base plate. An optimal carbide composition ensures homogenous bonding between the basemetal and overlay, adding to the overlay’s high wear resistance and long service life.
