Red Dog T200X™
GENERAL DESCRIPTION
The T200X overlay alloy for steel plate has been developed for applications requiring high resistance against wear by abrasion combined with moderate to low impact.
Since its introduction to the market place, Red Dog T200X has established itself as the leading general purpose wear resistant alloy, meeting a wide variety of requirements in a large number of fields of application and industry segments.
TYPICAL PROPERTIES OF UNDILUTED T200X ALLOY
The properties given directly below refer only to the T200X 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.
