WEARcore 714 N-O is a self-shielded cored wire that deposits a ferritic martensitic steel with an addition of nitrogen, made to resist metal to metal wear, corrosion and thermal fatigue. The typical application is continuous casting rollers.
The shielding comes from the core, so no cylinder or regulator is needed at the station and the wire suits outdoor work, wind included. It goes into maintenance work, rebuilding dimensions and strengthening surfaces exposed to wear.
- Classification EN ISO: 14700 T Fe7
- AWS classification: 8555 MF 5-GF-45
- Shielding: self-shielded, no shielding gas
- Diameters: 2.4 mm
- Hardness of deposit: 44 HRC
Lay the overlay in overlapping beads and watch the temperature of the part, an overheated piece will distort and crack at the layer boundary. Check the polarity before you start, self-shielded wires often run differently from solid wires. Keep the stick-out recommended for self-shielded wires, too short a one spoils the pool shielding and causes porosity. Previously sold as SK 714 N-O.
