14C28N
14C28N is what happened when Sandvik took their razor steel lineage and fixed the rust. Developed with Kershaw for production folders, it keeps the fine-carbide structure that makes AEB-L the toughness king of affordable stainless, then swaps a little carbon for nitrogen — buying noticeably better corrosion resistance without the big chromium carbides that make lesser budget stainless steels chip and grind like glass. Factory knives run it soft; makers who push it to 61–62 HRC find one of the best value-for-performance stainless steels ever offered.
14C28N FAQ
Is 14C28N a good knife steel?
One of the best budget stainless choices there is. Toughness at the top of the stainless class alongside AEB-L, corrosion resistance the best of that family, a fine keen edge, and easy grinding and finishing. Its one honest weakness is wear resistance — with no vanadium carbides it will not hold a working edge like the powder steels, though it sharpens back in moments.
What is the difference between 14C28N and AEB-L?
Chemistry-wise, nitrogen and a touch more chromium. AEB-L runs slightly tougher and can be pushed a point harder; 14C28N stains meaningfully less — it was literally engineered for wet razor duty. For a kitchen knife that lives rinsed-and-wiped, that margin matters. Full breakdown in our 14C28N vs AEB-L comparison.
How do you heat treat 14C28N?
Austenitize at 1950°F for 10–15 minutes, plate quench between aluminum plates, then a cold step — a household freezer helps, liquid nitrogen is better — to convert retained austenite. Temper twice at 300–350°F for 60–62 HRC. Skip the cold step and expect to give back a point or two of hardness.
Why do factory knives run 14C28N soft?
Production lines temper to 58–60 HRC for warranty margins, and the steel’s budget reputation was built there. At 61–62 with a proper cryo step its edge retention improves markedly while the toughness headroom keeps it far from brittle — the maker’s version is simply a better knife than the factory version. The tradeoff logic lives in Why Hardness Matters.
Is 14C28N hard to grind?
No — it is one of the friendliest stainless steels on a belt. Fine carbides mean ceramic belts cut it cleanly, it hand-sands to a respectable finish for a stainless, and it takes a crisp edge on ordinary stones. See our grinding and sharpening guide.
What knives suit 14C28N best?
Kitchen knives above all — toughness for thin edges, stain resistance for the sink — plus EDC folders, fillet knives and anything that lives near water. It is also a forgiving first stainless for a maker stepping up from carbon steel.
Also known as: Sandvik 14C28N, Alleima 14C28N; family successor to 13C26 (itself AEB-L's twin)
Composition
Carbon 0.62%, Chromium 14.0%, Nitrogen 0.11%, Manganese 0.60%, Silicon 0.20% — nitrogen substitutes for carbon to boost corrosion resistance without coarse carbides
Properties
| Property | Rating | Notes |
|---|---|---|
| Toughness | ★★★★★ | Top of the stainless class with its AEB-L family — far beyond mainstream budget stainless, and in league with good carbon steels. AEB-L itself keeps a slight edge at equal hardness, but 14C28N supports thin edges and hard use that would chip conventional stainless outright. |
| Edge Retention | ★★☆☆☆ | The honest weak point, shared with AEB-L: fine carbides and no vanadium means modest wear resistance. Pushing hardness to 61–62 HRC with a cold treatment recovers a lot of real-world edge holding — factory-soft examples undersell the steel. Resharpening is fast and pleasant. |
| Corrosion Resistance | ★★★★☆ | The best of the AEB-L family — 14% chromium plus nitrogen, engineered for wet razor service. Kitchen and waterside use with basic care is no drama. Not quite the vault-grade resistance of nitrogen specialists like LC200N, hence 4 not 5. |
| Machinability / Grinding | ★★★★★ | As friendly as hardenable stainless gets: fine structure, no carbide tear-out, cuts cleanly on ceramics, hand-sands better than almost any other stainless, and finishes crisply. Belt life is good and the steel telegraphs no surprises. |
Heat Treatment
Austenitize 1950°F, 10–15 min soak. Plate quench between aluminum plates; add a cold step (freezer at minimum, liquid nitrogen ideally) before tempering to convert retained austenite. Temper 2×2h at 300–350°F for 60–62 HRC. Production practice of 58–60 HRC works but leaves performance on the table.
Best Uses
Kitchen knives, EDC folders, fillet and bird-and-trout knives, salt-air and waterside blades, and a first stainless for makers moving up from carbon steel. Anywhere a tough, easy-care, easy-sharpening edge beats maximum wear resistance.
