General Product Description

Duroxite® 100 WIRE is a flux-cored welding wire for hardfacing components subject to severe sliding wear and moderate to low impact applications using an open-arc welding process. 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 HK1) 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.

1) HK is the Knoop microhardness used primarily for very brittle materials.

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 350ºC (660ºF). Typical examples include: Crusher hammers, gyratory crusher cones and mantles, dredging pumps, slurry pipes, dragline bucket liners, coal pulverizer rolls, coke hammers, sand dredging parts, mining and earthmoving components, and sorting screens.

1) Surface hardness is measured on machined flat surface just below overlay surface.

2) ASTM G65 is a standard test measuring sliding abrasion resistance using a dry sand/rubber wheel apparatus. ASTM G65-Procedure A is the most severe test method.

3) ASTM G65 wear test is conducted at 75% depth of the overlay materials to ensure consistently good wear resistance from the top surface through to the depth of 75% of the overlay.
