Overlay pipe withstands transport of wet, dry abrasives

Hardox Wearparts offers SSAB Duroxite™ 100 pipe, an overlay product that provides extended service life when transporting wet or dry abrasives materials for mining, cement, dredging, recycling, steel mill, and oil sand applications.

According to the company, consistent wear properties are guaranteed throughout the pipe 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 helps ensure homogenous bonding between the base metal and overlay.

The pipe is manufactured by welding chromium-rich, abrasion-resistant materials inside a mild steel pipe. Extremely hard chromium-rich carbides with a typical hardness of 1,700 HK are dispersed in a ductile eutectic austenite matrix.
