CHROMEWELD 600™

Chromium Carbide Overlay Plate | Chrome Carbide

JADCO CHROMEWELD 600™ is a unique material that is ideal for surfaces requiring high levels of abrasion resistance. It is a premium grade of chromium carbide wear plate. Produced with a mild steel (A36) base plate and hardfaced/overlayed with our proprietary JADCO CHROMEWIRE.

CHROMEWELD 600™ Fabrication Facts

Regardless of whether a CHROMEWELD 600™ application requires machining, cold bending, welding, CHROMEWELD 600™ will yield outstanding results if you follow these helpful instructions.

Cutting:

Plasma burning, air arc, abrasive saw cutting, or waterjet.

Machining:

The overlay surface can be finished by grinding only. EDM, plasma arc cutting, or carbon-arc gouging may produce countersunk holes for bolts. Pre-machined mild steel inserts may be welded into straight holes for additional machining. CHROMEWELD 600™ cannot be machined by ordinary methods.

Cold Bending:

When using a press brake, forming should be perpendicular to the weld pass direction. Plate rolling should be performed in the direction of the overlay beads. Forming CHROMEWELD 600™ to the outside will cause cross-check cracks to open. This may require post-fabrication weld repair using suitable weld rod/wire.

Welding:

CHROMEWELD 600™ overlay plate can be joined by welding substrate to substrate using 309 weld wire/rod. Liner plates can be plug welded in place by welding the substrate to the base plate. Stud welds can be applied, but it is highly recommended that stainless steel studs be used. All weld seams, plug-weld holes, bolt holes, and all other joints exposed to wear should be protected by a cap weld of JADCO CHROMEWIRE.

CHROMEWELD 600™ Mechanical Information

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.

In general, the overlay chemistry of the CHROMEWELD 600™ material is as follows:

The surface of plate is a composite of chromium iron carbides in a chromium austenitic matrix. Typical hardness of the CHROMEWELD 600™ is 58-62 HRC, depending on the thickness of the overlay.

»  Standard Plate size is 90” X 120”.

»  CHROMEWELD 600™ displays excellent abrasion resistance and will withstand continuous moderate impact.

»  CHROMEWELD 600™ overlay will remain abrasion resistant at temperature up to 1100 degrees Fahrenheit.

»  Standard thickness range from 1/8” on 3/16” (.3125”) through 1/2” on 1/2” (1”)

»  JADCO can manufacture plate to your specific application including custom requirements such as thickness,
   alloy and size.

The JADCO process produces a mircostructure consisting of fully austenitic matrix filled with primary carbides. This structure provides outstanding abrasion resistance in the most challenging applications.
