WEARcore 430-O is a self-shielded cored wire that deposits a ferritic steel with 17 % chromium, made to resist corrosion at high temperature. Typical applications are continuous casting rollers at the top of the line and valve seats.
It needs no shielding gas, which makes work outdoors and in wind simpler, and it is used on valve seat repair, on rebuilding shafts, rollers, screws and blades and on surfaces working under abrasion.
- Classification EN ISO: 14700 T Fe7
- AWS classification: 8555 MF 5-GF-250-C
- Shielding: self-shielded, no shielding gas
- Diameters: 2.4 mm
- Hardness of deposit: 250 HB
On hard deposits expect a network of shrinkage cracks, on working overlays that is normal, but it must not reach the parent material. Keep the stick-out recommended for self-shielded wires, too short a one spoils the pool shielding and causes porosity. Work with fume extraction, self-shielded wires smoke far more than gas shielded ones. Previously sold as SK 430-O.
