SHS 9700 wear plate is a high hardness material with significantly better wear resistance than chrome carbide overlay plate. The very fine grain structure of SHS 9700 also provides toughness equivalent to most standard materials. These properties make SHS 9700 well suited for applications with severe sliding abrasion and moderate impact.

High Hardness
High hardness gives SHS 9700 very good resistance to sliding abrasion which is commonly found in chutes, liners and other similar applications. SHS 9700 is a through-hard material, attaining full hardness within approximately ~ 125 µm of the base metal surface.

High Wear Resistance
High wear resistance of SHS 9700 is the result of the refined near nanoscale microstructure and even distribution of fine borocarbide phases. SHS 9700 has been compared to standard chrome carbide overlay plate by means of an ASTM G65-04 Procedure A test measuring low stress abrasion resistance. When applied as a one or two layer weld overlay, ASTM G65-04 wear tests showed SHS 9700 to have a 40% increase in wear resistance over chrome carbides.

Elevated Temperature Stability
Elevated temperature stability is possible due to complex transition metal formations which result in elevated temperature hardness and improved elevated temperature performance.

Formability
SHS 9700 wear plate can be rolled or press brake formed to desired shapes for the application. Formability is similar to standard overlay plates and dependant on thickness and weld position on the ID or OD. In the image to the right, two typical radii for an SHS 9700 single pass overlay can be seen. The SHS 9700 wear plate with the tighter radius has been formed with the weld on the ID.

Cutting
Plasma arc cutting is recommended for shape cutting and large hole piercings. SHS 9700 overlays, like chrome carbide, cannot be flame cut. For applications requiring less precision, the overlay material can also be removed by means of carbon arc gouging. SHS 9700 overlays are non-machinable and surface finishing may be done by grinding.

Installation
SHS 9700 wear plate can be bolted or welded into place by plug or fillet welding. To protect plates from wear caused by undercutting of the overlays at the seams, any weld seams should be overlaid with SHS 9700 GMAW OAW wire.
