Stoody SOS 423
The SOS 423 deposit is a stabilized martensitic stainless steel. It is a fire-crack resistant alloy that has excellent corrosion and wear resistance. The wire is specifically designed for a two-layer over-lay on continuous caster rolls. It is designed to be used with SOS 430 as the underlay, and used as a 2-layer overlay in the untempered condition for best wear and corrosion resistance. It can be applied using either a weave bead or stringer bead technique. On smaller rolls, the stringer bead technique is preferred.
