Red Dog T137X
The T137X overlay alloy for steel plate has been developed for applications requiring good resistance against wear by abrasion combined with a higher level of impact resistance than that of T200X and T211X overlaid plates.
TYPICAL PROPERTIES OF UNDILUTED T137X ALLOY
The properties given directly below refer only to the T137X alloy, undiluted by base material (substrate). These properties differ from the properties of actual overlay deposits on a particular substrate, examples of which are given in the next section.

|Group of alloys||High chromium iron with added NbC|
|Nominal composition (undiluted)||3.8% C, 3.5% Mn, 22% Cr, 9% Nb, 0.5% V|
|Microstructure||Hypo-Eutectic with uniformly dispersed-fine Nb-carbides|
|Typical hardness range||47-52 Rc|
|Impact resistance||Moderate to High|

AREAS OF INDUSTRIAL USE
The T137X overlaid plates are used in many segments of industry: Steelworks, Dredging, Mining, Refineries, Cement, Glass, Timber, Power Generation Plants, Earthmoving, Sugar Mills, etc., where a compromise between slightly reduced abrasion resistance but higher impact resistance than for T200X and/or T211X is required.
TYPICAL FIELDS OF APPLICATION
Shovel bucket wear liners
Chutes and decks of all types and sizes
Auger flights, etc.
Ball mill liners
Conveyer transfer points
Truck bed liners.
