Steel matchup
14C28N and Nitro-V, compared on the five things that decide a blade: toughness, edge retention, corrosion, heat treat and how each one grinds.
Sandvik's razor-lineage stainless, designed with Kershaw: AEB-L's fine-carbide toughness with nitrogen chemistry that delivers the best corrosion resistance in the budget class. Run soft in factories, outstanding at a maker's 61–62 HRC — the thinking maker's budget stainless.
A modern stainless steel built from AEB-L with added nitrogen and vanadium, combining high toughness, solid edge retention, and strong corrosion resistance.
Dimension by dimension
Each steel's own note, its score out of five, and what separates the two in that one column. The higher score in a row is marked in purple.
| Dimension | 14C28N | Nitro-V | What separates them |
|---|---|---|---|
| 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. | One of the toughest stainless steels available, inheriting AEB-L's excellent toughness while adding a bit more wear resistance from vanadium and nitrogen. | Both inherit the family's elite stainless toughness; Nitro-V tested at its best runs with AEB-L, and 14C28N sits a breath behind. All three support thin, hard-use edges. No build should turn on this margin. |
| 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. | Similar to AEB-L: good, not exceptional, since it relies on a fine, clean microstructure rather than heavy carbide loading for its edge. | Nitro-V by a small, real margin — its vanadium adds a little wear resistance the others lack, on top of the same keen fine-carbide edge. 14C28N pushed to 61–62 with cryo narrows it. Both resharpen in moments. |
| 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. | 13.6% chromium plus nitrogen gives genuinely good stainless performance, a step up from AEB-L and well suited to kitchen and outdoor use. | 14C28N, slightly — 14% chromium plus 0.11% nitrogen edges Nitro-V's 13% plus smaller nitrogen addition. Both are dramatically better than AEB-L in wet service; 14C28N just has the deepest margin of the family. |
| Heat treat | 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. | Austenitize at 1900-1950 F for 15 minutes (use the lower end if following with a freezer rather than liquid nitrogen). Plate quench, then apply a cryogenic treatment (liquid nitrogen or a home freezer) before tempering. As-quenched hardness can reach roughly 64 Rc. Temper at 300-350 F: 300 F favors maximum hardness and edge stability, while 350 F gives the best overall toughness balance for most knife use. Avoid tempering near 450 F, which shows an unexpected drop in toughness for this steel. | Same playbook for both: ~1950°F austenitize, plate quench, cold treatment strongly recommended, low temper for 60–62 HRC. Nitro-V has excellent maker-community documentation (it was commissioned for makers); 14C28N has Sandvik's own datasheet depth. Neither is harder than the other. |
| 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. | Processes well with standard knifemaking tools and is considered forgiving to grind and heat treat for a stainless steel. | A tie — the AEB-L family manner runs through both: clean belt behavior, fine finishes, no carbide tear-out, unusually pleasant hand sanding for stainless. Nitro-V ships in more knife-specific sizes from maker suppliers, which is its quiet practical advantage. |

The long answer
Two answers to the same question: what does AEB-L look like with nitrogen? New Jersey Steel Baron commissioned Nitro-V (AEB-L chemistry plus nitrogen and vanadium); Sandvik built 14C28N (more chromium, more nitrogen, no vanadium). Both deliver the fine-grained stainless formula with better corrosion manners than their ancestor — and they split the remaining differences almost evenly.
