WEARcore 430-S is a submerged arc cored wire that deposits a ferritic steel containing 17 percent chromium, made to resist corrosion at high temperatures, used on continuous casting rollers from the top of the line and on valve seats.
Submerged arc welding gives a very high deposition rate on long, repeatable welds. The wire is used to recondition valve seats and to work on crusher parts, conveyors, ploughshares and mining machinery. Previously sold as SK 430C-SA.
- Classification EN ISO: 14700 T Z Fe9
- AWS classification: 8555 UP 5-GF-200-C
- Shielding: flux matched to the wire, no shielding gas
- Hardness of deposit: 175 HB
Lay the overlay in overlapping beads and watch the part temperature, an overheated component will distort and crack where the layers meet. Match the flux to this wire and check how dry it is, drying the flux decides the hydrogen level in the weld. Keep an even flux layer over the arc, too thin a layer exposes the arc and too thick a one spoils the bead shape.
