General Description

AS SD-ABRA Nb is a basic coated electrode that is highly resistant to abrasion wear caused by fine or coarse hard minerals. Concentrated Cr and Nb carbides have been finely dispersed in its structure. In corrosive environments, it gives a better resistance to wear caused by fine minerals than hardfaced structures having an ordinary chromium carbide structure.

Applications

Wear plates, dredgers, rock crushers, grinding hammers and rollers can be hardfaced with AS SD-ABRA Nb. It should not be used for more than three passes.

In applications requiring a thick deposit metal, AS P-308 Mn or AS P-312 should be used for buffering. It is crucial to have a buffer layer with AS P-308 Mn for 12-14 % Mn containing steels before hardfacing applications
