Description:
FW—2103 is a high chromium, high boron alloyed cast iron type hardfacing electrode. The structure of deposited metal is alloyed martensite with metal carbide. It performs good resistance to grinding abrasion or erosion with large particles and large angle.
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:
Fan mill liners, dredger pump impeller, house casing, dredging teeth, coalbreaker roller, etc.

Notes:
1、FW—2103 fluxed 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、In some cases, FW-4101or FW-4102 should be applied as the buffering layer.
4、Preheating and slow cooling after welding is necessary for some main parts.
