HARDFACE HC-O
EN 14700 T Fe15
• High chromium cast iron for hardsurfacing components subject to extremely severe abrasive wear and moderate impact
• The deposit contains a high proportion of hard primary chromium carbides in a tough austenitic matrix
Hardface HC-O is used for hardfacing components undergoing wear by earth, sand and abrasives.
Examples
Gyratory crusher cones and mantles, catalyst pipes and valves, slurry pipes and valve bodies, dredge pump bodies, sand dredge parts, extruder screws, “barmac” crushers, mining and earthmoving equipment, blast furnace bells, brick muller tyres, sugar mill crusher hammers, drag line components, coal pulverisor rolls, coke hammers, cone knives and shredders. Relief checking is normal and best limited to two layers unless impact loading is small. Can be multi-layered in specific applications.
