COROLOY® E Co
DIN EN 14700
High alloyed nickel based AC electrode with 160 % recovery. The COROLOY E Co type deposit has outstanding physical characteristics and is resistant to both, oxidation and reduction corrosion. It work hardens under impact and by machining to app. 400 HB even at high temperatures – without deforming the deposit. Thick layers should be buffered with CORODUR E 29/9.
COROLOY E Co is used in general for surfacing of all work-pieces subject to mechanical stress combined with corrosion and/or to high temperatures (from 400 – 750°C).
Main applications: Surfacing of hot working tools as hot shear blades, punches, deburring tools, swages, dies, press tools, milling rolls and valves, etc. To achieve a crack-free overlay, the base material should be preheated to 300 – 400°C, depending on the alloy.
