| Duroxite Cr-free Wire is a non-chromium bearing flux cored hardfacing wire for open arc welding. The deposited overlay contains boron carbides which has wear resistance and hardness equal to or greater than conventional chromium carbide deposits. Duroxite Cr-free Wire is specifically formulated to eliminate chromium in the wire, and still provide outstanding wear resistance. Since there are no chromium alloys added in the welding wire, the emission of hexavalent chromium during welding is reduced or completely eliminated (depending on the chromium content in substrate materials or pre-existing weld deposit). Duroxite Cr-free Wire is a good choice of hardfacing wire for earthmoving applications when the hexavalent chromium smoke is a big concern at the workshop. It is suitable for single and double-layer deposit. Preheating, interpass temperature, and post-weld heat treatment are as needed according to base metal recommendations. If welding with downhill or uphill position, reduced wire feed speed and voltage are preferred to apply. Key Benefits - Duroxite Cr-free Wire provides very good abrasion resistance for earthmoving applications where hexavalent chromium in welding fumes cannot be reduced by work practice controls.
- Duroxite Cr-free Wire maintain same wear resistance guaranteed from surface through 75% depth of overlay in multi-layer deposit.
Typical Applications: Duroxite Cr-free Wire is used for hardfacing components undergoing wear by earth, sand and abrasives in the agricultural, quarry, mining, and public works fields. Examples: Mixer shafts, impellers, buckets, shovels, transport screws, and crushers for the concrete industry.Data provided by SSAB. |
