EN 14700 E Co3
TS EN 14700 E Co3
DIN 8555 E 20-UM-55-CSTZ

Properties and Applications

Rutile-basic coated hardfacing electrode which deposits Co-Cr-W alloy weld metal. Suitable to use in hardfacing of parts subjected to either the single or combined effect of: heavy metal-to-metal wear or abrasion, high temperatures (ranging from 500°C to 900°C) and corrosive environments. Due to its very high hardness it is recommmended for applications where shocks are low or moderate. Preferred to use with DC, electrode in positive (+) and possible to use with also AC. 

Typical Applications: Suitable for rolling mill guides, extrusion dies, valve seats, mechanical parts of steam turbines, pump tubing and shafts and mixer blades.
