Red Dog T211X™
The T211X overlay alloy for steel plate has been developed for applications requiring high resistance against wear by high and low stress abrasion, as well as erosion combined with moderate to low impact.
TYPICAL PROPERTIES OF UNDILUTED T211X ALLOY
The properties given directly below refer only to the T211X 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.
|Type of alloy||Iron based|
|Group of alloys||High chromium iron|
|Nominal composition (undiluted)||4.9% C, 3% Mn, 33% Cr, +1%B|
|Microstructure||Hyper-Eutectic with M7C3 primary chromium carbides in a martensitic eutectic matrix|
|Typical hardness range||57-62 Rc|
|Typical service temperature||Up to 650°C (1,200°F)|
TYPICAL PROPERTIES OF T211X OVERLAID PLATES
Standard Base plate grades:
|in the USA:||ASTM A-36|
|in the UK||BSEN 10025:1993 Fe 430A (BS 4260-43A)|
Typical chemical compositions and hardnesses of single and double layer overlays:
T211X overlaid plates are used in many segments of industry: Steelworks, Dredging, Mining, Refineries, Cement, Glass, Timber, Power Generation Plants, Earth moving, Sugar Mills, etc which are basically the same as for T200X. T211X plates are however preferentially used in situations of small particle impingement and erosion.
