FW CoCr-A

AWS: SFA 5.21 ERCoCr-A

EN ISO CODE:

Weld metals deposited by FW CoCr-A rods are characterized by a hypo-eutectic structure, consisting of a net work of about 13% eutectic chromium carbides distributed in a cobalt-chromium-tungsten solid solution matrix. This weld metal is good for resisting metal to metal wear, particularly in high load situations that are prone to galling. This weld deposit has got excellent resistance to corrosion, oxidation, and elevated temperature retention of hot hardness up to 650°C. It is used primarily to resist wear where elevated temperatures and corrosion is involved. Specific applications include Automotive and fluid flow valves, chain saw guides, hot punches, shear blades & extruder screws.
