XT Block is a composite white iron wear surface vacuum brazed to weldable mild steel backing plate, buttons, blocks and bars.
The XT Block wear bar is typically welded to the surface of mining buckets and teeth/adaptors to provide protection from severe abrasion and impact encountered in service.
The wear resistant white iron component conforms to Australian Standard AS2027 and is a CrMoCu-1521 (15%Cr 2%Mo 1%Cu) martensitic white iron alloy.
The XT Block wear bar has excellent hardenability, is produced with a minimum bulk hardness of 700 BHN and contains primary carbides of up to 1500 HV.
The XT Block wear bar is supplied in a variety of sizes and incorporates a notched backing, making it easy to cut to size and bend to offer protection on a contoured surface.
