Game-changingtechnologyExpanite is a game-changing surface hardening process for stainlesssteel that will make you and your customers much more competitive.Our patented and proven technology, scientific know-how andflexible delivery model significantly improves product performance,quality, and reduces costs.Not just anothercoatingThe Expanite treatment effectively removes the oxide film coveringstainless steels. This allows controlled incorporation of carbonand nitrogen atoms in the underlying metal. The hardened layer ischaracterized by an expansion of the material structure. We callthis zone expanded austenite, expanded martensite, or simply,Expanite.Expaniteprocesses... are applicable to the most common stainless steel alloys including austenitic, martensitic, ferritic and duplex grades are gaseous, thus properties can be tailored to match your exact needs can deliver parts that withstand 1000+ hours in salt spray,while having a controlled surface hardness of 1000-1800HV run on a day-to-day basis, resulting in lead-times significantly lower than alternatives can either be offered from our treatment center or implemented on-site, directly in your production lineTailor-made solutions to yourneedsExpaniteHigh-TA high-temperature solution-nitriding process pushing nitrogen deepinto the bulk material. This re-establishes the core hardness ofthe material, which creates a unique load-bearing capacity andsecures corrosion resistance second-to-none.Benefit: Get all the best things of annealing while maintainingcore hardness and increasing corrosion resistance.ExpaniteLow-TA low-temperature surface-hardening process, by which a doublehardened zone containing nitrogen and carbon is established.Nitrogen adds increased surface hardness while carbon bridges thegap to the softer core. A smooth hardness profile is tailored!Benefit: Controlled surface hardness between 1000-1800HV.SuperExpaniteBy combining the ExpaniteHigh-T and ExpaniteLow-T processes you geta previously unseen surface hardness founded on top of a bulkmaterial, which has very strong load-bearing capacity. Superiorcorrosion, wear and fatigue properties is the outcome –SuperExpanite is simply setting new standards for what can beachieved by surface-hardening stainless steel.Benefit: Superior corrosion, galling, fatigue and wearproperties.Expanite—Beyond theSurfaceBased on ongoing research since 2000, and founded in 2010 byleading scientists in the field of surface hardening, Expanite hasits roots deeply planted in a fact-driven environment.The philosophy is quite simple; we want to offer the best solutionsfor surface-hardening of stainless steel! Today, Expanite ischanging the game by not only moving the limits of what performancecan be expected from stainless steel but also by letting ourcustomers implement the processes directly in their facilities.From our state-of-art facility just north of Copenhagen, Denmarkwith full-size furnaces and laboratory capabilities, to theshop-floor of our customers, we want to give our customers acompetitive edge.
