EN 14700 E Co2
TS EN 14700 E Co2
DIN 8555 E 20-UM-40-CTZ

Properties and Applications

Rutile-basic type 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 higher toughness and shock resistance extends its use for service conditions involving mechanical impacts and thermal shocks. Preferred to use with DC, electrode in positive (+) and possible to use with also AC. 

Typical Applications: Suitable for blades for hot shearing, ingot tong ends, glass moulds, valves and valve seats, nozzles
