Cobalt #1 - Coated Electrodes, bare rods, and welding wires 
            Hardness: 50-55 Rc 
            AWS A5.13 RCoCR-C (bare) ECoCr-C (coated) 
            Mil R-17131, Type MIL-RCoCr-C-1 are available also. 


A cobalt based alloy with outstanding resistance to abrasion, heat and 
corrosion.  This alloy has a low coefficient of friction and acquires a 
high polish in service. This alloy is not recommended in applications 
involving impact or where crack-free weld deposits are required. 
General uses include the overlay of extrusion screw conveyors, valve 
stems and bearings.


Cobalt #6 - Coated Electrodes, bare rods, and welding wires 
            Hardness: 40-45 Rc 
            AWS A5.13 RCoCr-A (bare) and ECoCr-A (coated) 
            Mil R-17131, Type MIL-RCoCr-A-1, and AMS 5788 
            are available also. 


This is the most generally used cobalt alloy, having excellent resistance 
to many forms of mechanical and chemical degradation over a wide 
temperature range.  This alloy exhibits high tensile strength, metal to 
metal wear, corrosion and erosion properties.  It is ideally suited to a 
variety of hardfacing processes.  Uses include overlays on valves, hot 
shear blades, punches, and chain-saw bars.  Bonds well with weldable 
alloys steels, including stainless.


Cobalt #12 - Coated Electrodes, bare wires and welding wires 
            Hardness: 48-52 Rc 
            AWS A5.13 RCoCr-B (bare) and ECoCr-B (coated) 


Similar to Cobalt #6 in composition with the difference between 
the alloys being one of carbide volume, therefore high hardness and 
resistance to abrasion.  Overlays resist abrasion, corrosion and mod- 
erate impact and acquire a high polish in service.  Uses include over- 
lays on screw conveyors and augers in the rubber and plastic industry, 
engine components for gas and diesel engines, and extrusion screws 
and various valves.


Cobalt #21 - Coated Electrodes, bare wires and welding wires 
            Hardness: 33-36 Rc as welded, work hardens to RC 45+ 
            Specification: UNS-R30021 


The least crack-sensitive of all the cobalt based alloys.  This alloy, a low 
carbon, molybdenum strengthened cobalt-chromium alloy will work 
harden to Rc 45+ with excellent impact and metal to metal wear qual- 
ities, especially at high temperatures.  Uses include overlays in hot 
extrusion and forging dies, trimmers, punches and hot shear blades.


All of the above listed cobalt materials are available in spools, cut lengths and covered electrodes.
