Description:
FW—3103 is a high-chromium, boron complicated alloyed cast iron type hardfacing electrode. The structure of deposited metal is high-alloyed austenite. It performs good resistance to high temperature & abrasion and metal-to-metal wear large impact. In some cases, it can substitute for cobalt-based alloy.
This product has no special requirements for welding equipment. Both AC and DC can be used with stable arc, easy operation, easy slag removal and good surface finish.

Typical applications:
Casting machine, hydraulic scissors cutter blades, special valve seal involved high-temperature. When hardfacing the gas furnace valve seal, it is better than CoCrw alloy.

Notes:
1、FW—3103 electrode should be baked for one hour with the temperature of 300°C before use.
2、A maximum deposit of 3 layers with a thickness of 8mm is highly recommended.
3、FW-8101 should be applied as the buffering layer.
4、Preheating of 400—500℃ for the component is necessary.
