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
- Same wear resistance guaranteed from surface through 75% depth of overlay in multi-layer deposit
- Optimal alloy formulation that forms a carbide composition which provides a good combination of wear resistance and homogenous bonding
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.
1)HK is the Knoop microhardness used primarily for very brittle materials.
