說明 Characteristics. Welds made using ECoCr-E electrodes have very good strength and ductility at temperatures up to 1600°F [870°C]. Deposits are resistant to thermal shock, and oxidizing and reducing atmospheres. Early applications of these types of alloys were found in jet engine components such as turbine blades and vanes.
The deposit is a solid-solution-strengthened alloy with a relatively low weight-percent carbide phase in the microstruc-ture. Hence, the alloy is very tough and will work harden. Deposits possess excellent self-mated galling resistance and also are very resistant to cavitation erosion.
Applications. Welds made using ECoCr-E electrodes are used where resistance to thermal shock is important. Typical applications, similar to those of ECoCr-A deposits, include guide rolls, hot extrusion and forging dies, hot shear blades, tong bits, and valve trim.
