Description:
1、FW—1103 is a high Chromium, high Boron and high alloy cast iron type hardfacing electrode. The deposited metal consists of carboborides and eutectic phase. It offers the best resistance to low-stress in FW-11XX family and the maximum service temperature is up to 700℃.
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.
2、The gradation of the properties is FW-1101

Typical applications:
Concrete mixer impellers, concrete pump S-valve, glass mixer impellers, scraper, components involving heavy abrasion with the medium working temperature (no more than 600℃) in sinter, iron-making, coking, and cement industries.

Notes:
1、FW—1103 electrode should be baked for one hour with the temperature of 300°C before use.
2、The optimum results can be achieved by hardfacing only a single layer. Multilayer is not recommended.
3、The deposited metal offers excellent resistance to low-stress abrasion, but it is very brittle with low toughness, so it is not suitable for high impact or collision applications.
4、In some cases, FW-2101 should be applied as the buffering layer.
