Extreme Abrasion Resistant Chromium Carbide Overlay Plate
CHROMEWELD™ 600 CHROMIUM CARBIDE PLATE
CHROMEWELD™ 600 is the global standard in abrasion resistant chromium carbide plate. It is a 600 Brinnell chromium carbide plate that is manufactured by JADCO, and is ideal for surfaces requiring high levels of abrasion resistance. CHROMEWELD™ 600 has been proven in the coal mines of Appalachia, the aggregates of North Carolina, and the Gold fields of Africa.
Incredible hardness, unrivaled performance
Precision-manufactured with a mild steel (A36) base plate and hardfaced/overlayed with our proprietary wire, CHROMEWELD™ 600 is a premium grade of chromium carbide plate. Alternative options available for the base plate, including but not limited to: A572 and stainless steel.
CHROMEWELD™ 600 typical hardness ranges from 58-62 HrC based on weld deposit thickness. The surface of plate is a composite of chromium iron carbides in a chromium austenitic matrix. The surface of the plate exhibits numerous hairline cracks which are a natural stress relieving phenomenon that is essential to the performance of the plate and enable it to be formed, bent, and rolled without damage.
The JADCO process produces a microstructure consisting of fully austenitic matrix filled with primary carbides. This structure provides outstanding abrasion resistance in the most challenging applications.

CHROMEWELD™ 600 Fabrication Facts
Mechanical Information
Welding: CHROMEWELD™ 600 overlay plate can be joined by welding the substrate to work piece using JADCO FUSION™ Universal, a high strength, work hardened stainless steel that can be welded to dissimilar metals, designed for harsh working environments. Please note that 309wire/rod and similar wire/rod may also be used. Typical structural rods/wires such as E7018, E71T1 and similar may also be used so long as the weld bead stays 2mm below the hard face material. For substrate to substrate joining, use Jadco Fusion Universal or 309 weld wire/rod. Liner plates can be plug welded to the work piece. Stud welds can be applied. It is highly recommended that stainless steel studs be used. All weld seams, plug weld holes, bolt holes and all joints exposed to wear should be protected with surface welds of JADCO FUSION™ 600.
