Universal Cobalt Alloy No.12 |
||
| Description: | Universal No.12 is a cobalt-chromium-tungsten alloy suited for applications requiring extreme abrasion and corrosion resistance with moderate impact. The deposited hardness range of Rc 48-52 remains intact under operating temperatures of 1500 F. The excellent resistance to hot and cold abrasion, corrosion and erosion suits Universal 12 to numerous applications. Universal No. 12 application include: rocker arms, trimming dies, mixers, cutters, extrusion and conveyor screws, seats and valves for oil and gas, chipper knives, paper rolls, bushings, saw teeth, entry guides, shafts, shaft bearings, thrust washer, brake drums, tarpets, valve push rods and valve stem ends. |
