說明 Characteristics. This family of electrodes deposits weld metal containing finely dispersed chromium carbides plus one or more metallic carbides (vanadium, niobium [columbium], tungsten, or titanium). The resultant deposits are not machinable, and maintain their hot hardness and abrasion resistance to 1200°F [650°C]. Deposits stress-relief check readily.
Applications. Equipment subjected to severe high stress abrasion combined with moderate impact may be surfaced with one of the specific grades. Selection of the specific grade will be dependent on local service conditions and the specific application.
