The weld deposit contains abrasion-resistant materials composed of a high proportion of extremely hard primary M7C3 chromium-rich carbides. With a typical hardness of 1700 HK 1) these carbides are dispersed evenly in a ductile eutectic austenite matrix. It naturally reveals stress-relief cracks after welding.
Duroxite® 100 WIRE is suitable for single-layer or multiple-layer deposits up to a maximum of three layers.
Key Benefits
Typical Applications
Duroxite® 100 WIRE is mainly designed to use for hardfacing wear parts undergoing wear by earth, sand and abrasives up to 350°C (660°F). Typical examples include: Crusher hammers, gyratory crusher cones and mantles, dredge pumps, slurry pipes, dragline bucket liners, coal pulverizer rolls, coke hammers, sand dredging parts, mining and earthmoving components, and sorting screens.
