Uddeholm's European aristocrat, with extraordinary carbide refinement and corrosion protection.
Elmax
For the Newcomer
Elmax is a Swedish A process that atomizes molten steel into a fine powder before pressing it into a billet, producing very fine, evenly distributed carbides. stainless steel from Uddeholms, the same house behind AEB-L, one of the finest razor steels in the world. It has exceptional edge retention, genuine toughness at this hardness, and 18% chromium giving it corrosion resistance to spare. Its heat treatment profile is mature and well-documented, a real advantage for buyers who care about consistency between makers.
About this composition
The 18% Cr plus 3% V combination. In conventional melt this would produce large, clustered Microscopic hard particles within steel that resist wear. Their size limits how fine an edge can get, so smaller carbides allow a keener, more durable apex.. The powder process distributes them finely, making this combination viable and delivering very high wear resistance with very good corrosion resistance simultaneously.
Performance Deep Dive
Edge retention: Exceptional.
Toughness: Very good for its class.
Corrosion resistance: Excellent.
Ease of sharpening: Demanding.
High vanadium carbides resist abrasives. Diamond stones or premium synthetic waterstones are required.
Heat treat: Mature and well-documented.
Optimal at 61 to 62 HRC with Cryogenic treatment: chilling the blade far below room temperature after the quench to convert leftover soft austenite into hard martensite.. It has over a decade of validation behind it.
- vs. CPM MagnaCut: MagnaCut wins on toughness and corrosion; Elmax has the longer artisan track record.
- vs. S35VN: Elmax wins on edge retention; S35VN is easier to sharpen and slightly tougher.
- vs. SG2 / R2: very close edge retention; Elmax has slightly better corrosion (18% vs ~14 to 15% Cr).
In the Kitchen
Elmax shines on long-edge geometries: chef's knives, gyutos, and sujihiki slicers where edge retention matters most. Buy at the upper end of the HRC range (61 to 62) with cryogenic treatment for the best balance. The 18% chromium lets you cook acidic foods without worry, and standard kitchen care is all it needs.
Composition
| Element | % | Role |
|---|---|---|
| Carbon (C) | 1.7 | Very high; produces high carbide density for wear resistance |
| Chromium (Cr) | 18 | Highest in this guide outside the 440 family |
| Molybdenum (Mo) | 1 | Hardenability and secondary hardness |
| Vanadium (V) | 3 | Substantial vanadium carbide; primary wear resistance driver |
Steel family: PM stainless (Uddeholm HIP/spray-forming process, Sweden). 18% chromium combined with 3% vanadium produces fine, finely distributed carbides via powder metallurgy, a combination that would yield large clustered carbides in conventional melt.
