WEARcore Co 6 is a gas shielded metal-cored wire in a cobalt base alloy, for extrusion dies, hot working tools, turbine injectors, valve seats and ingot tong bits.
The metal core combines the deposition rate of a cored wire with an almost slag-free bead, as you get from a solid wire. The deposit is cobalt based, and the wire is used to recondition valve seats. Previously sold as SK STELKAY 6-G.
- Classification EN ISO: 14700 T Co2
- AWS classification: 8555 MF 20-GF-40-CTZ
- Shielding gas: M13, I1
- Diameters: 1.2 / 1.6 / 2.4 mm
- Hardness of deposit: 40 HRC
Lay the overlay in overlapping beads and watch the part temperature, an overheated component will distort and crack where the layers meet. Keep the gas cover complete, without a full slag layer the pool is more sensitive to draughts. Check the feed roll pressure, a metal-cored wire is easier to crush than a solid one. Match the diameter to the material thickness and the welding position, thinner wires are easier to control out of position.
