Two ExpaniteLow-T furnaces running final acceptance tests with Seco/Warwick in Poland – both are ready for shipping in September to two different locations in Asia. We will announce more about these new treatment sites shortly – stay updated on our LinkedIn profile.
SuperExpanite surface hardening replaces hard chrome plating
LIAG®LÄUFER, the specialist in hygienic shutter valves, had experienced challenges with abrasive wear and corrosion resistance. They tried different surface hardening solutions, which all caused corrosion after short time in use – then they found Expanite…
Sigma Phase in Duplex? – Never with Expanite!
Duplex stainless steels contain 2 types of microstructure, austenite and ferrite. Hence the name duplex.
In simple terms, the combination of these two phases is what causes duplex alloys to be highly sensitive with respect to the formation of the so-called “Sigma phase” (s-phase), because the s-phase primarily will form in the boundary between austenite and ferrite, growing into the ferrite.
