Product Catalog

ERCOCR-E


Alloy Type:

Alloy ERCOCR-E electrodes and rods have very good strength and ductility in temperatures up to 2100 degrees F.  Deposits are resistant to thermal shock and oxidizing and reducing atmospheres.  The deposit is a solid solution strengthened alloy with a relatively low weight-percent carbide phase in the microstructure.  Hence, the alloy is very tough and will work harden.

 

Typical Applications

Automotive exhaust valves

Steam Valves

Hot Shears

Forging Dies
