OK Flux 10.10
ESW
Type Basic
Description
OK Flux 10.10 is an agglomerated flux, designed for electroslag strip surfacing.
This flux is particular suitable for strip surfacing with stainless strips of the Cr,
CrNi and CrNiMo types, with or without Nb stabilisation. The weldability,
bead appearance and slag removal of OK Flux 10.10 are excellent.
