Duroxite® Cr-Zero Wire

Duroxite® Cr-zero 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-zero 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-zero 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.

Key Benefits

• Duroxite® Cr-zero Wire provides very good abrasion resistance for earthmoving applications where hexavalent chromium in welding fumes cannot be reduced by work practice controls.
• Duroxite® Cr-zero Wire maintain same wear resistance guaranteed from surface through 75% depth of overlay in multi-layer deposit.

Typical Applications

Duroxite® Cr-zero 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.

The welded overlay components can be processed by welding, cutting, forming and machining. Specific recommendations can be found in the Duroxite® Product brochure or by consulting your local technical support representative.
