                                                Duroxite® 100 Wire

                                                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 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.
