u WA Hardfacing Welding Alloys has developed a unique knowledge of crusher equipment and has designed a specific range of cored wires with wear characteristics to optimise the crushers performance, reducing maintenance costs. Hardfacing by arc welding is a surfacing operation using a cored wire to extend the service life of specific components. Weld Metal Comp. Mn,16 , Cr 14 , Ni, Fe, Si EN 14700 E Fe 9 358-SMAW 358- FCAW-O 358-FCAW-G Austenitic (hadfield steel type) Manganese alloy electrode for overlays which are subjected to extreme impact and pressure The overlay has a strong work hardening tendency,is highly crack resistant and high build ups are possible . Hardness 250HB MF 1-GF-400-P. Gas shielded flux cored wire, which is developed for hardfacing of parts, subjected to metal-to-metal friction wear (adhesion) and medium to high degree impacts. Weld metal can be machinable by chip forming by means of carbide tiped tools. Interpass temperature should not exceed 250C, during welding.
