In short
14C28N is a nitrogen-alloyed martensitic stainless steel developed by Sandvik of Sweden, usually hardened to around 58–62 HRC. It is genuinely good steel — easy to sharpen, tough, and very rust-resistant — which is why it is so common in folding and outdoor knives. In a kitchen blade it is a solid, budget-friendly choice, but it will not hold a fine edge quite as long as a harder Japanese steel such as VG10 or AUS-10.
What is 14C28N steel?
14C28N is a martensitic stainless chromium steel made by Sandvik, the Swedish steel producer, and designed specifically for knife blades. Its distinguishing feature is nitrogen: alongside the usual carbon and chromium, it carries a small, deliberate nitrogen addition that improves hardness and corrosion resistance at the same time — two things that normally pull against each other.
It is the refined descendant of Sandvik's earlier 13C26 and 12C27 blade steels, reworked in the late 2000s in collaboration with knife makers who wanted better corrosion resistance without giving up the easy sharpening those steels were known for. You will find it today across a very wide price range of production knives.
One correction worth making, because it is repeated a lot online: 14C28N is not a powder-metallurgy steel. It is conventionally melted and supplied as precision-rolled strip. That matters, because powder steels behave differently — they carry larger, harder carbides that hold an edge longer but fight you on a stone. 14C28N's fine, evenly distributed carbides are exactly why it sharpens so easily.
14C28N composition and hardness
Sandvik's published composition is roughly as follows. Small variations between production batches are normal.
| Element | Approx. % | What it does |
|---|---|---|
| Carbon (C) | 0.62% | Hardness and wear resistance |
| Chromium (Cr) | 14% | Corrosion resistance — this is what makes it stainless |
| Nitrogen (N) | 0.11% | The signature addition — hardness and corrosion resistance together |
| Manganese (Mn) | 0.6% | Hardenability |
| Silicon (Si) | 0.2% | Deoxidiser, aids hardenability |
| Phosphorus / Sulfur | ≤0.025% / ≤0.01% | Residual impurities, kept deliberately low |
Sandvik's recommended working hardness range is broad — roughly 55–62 HRC depending on heat treatment — and most knife makers land somewhere around 58–62. That is a genuinely useful window: run soft for a tough outdoor blade, or run hard for better edge retention. For context on what those numbers mean, see our guide to the Rockwell hardness scale.
14C28N vs VG10, AUS-10 and 12C27
No steel wins on everything. Edge retention, toughness, corrosion resistance and ease of sharpening trade against one another, and 14C28N is deliberately balanced rather than extreme.
| Steel | Typical hardness | Edge retention | Ease of sharpening |
|---|---|---|---|
| 14C28N | ~58–62 HRC | Good | Very easy |
| 12C27 | ~57–59 HRC | Fair | Very easy |
| AUS-10 | ~60 HRC | Very good | Moderate |
| VG10 | ~60–61 HRC | Excellent | Moderate |
Against 12C27, its older Sandvik sibling, 14C28N is the straightforward upgrade: more carbon and the nitrogen addition give better hardness and corrosion resistance for the same easy sharpening. If you are choosing between the two, there is little reason to prefer 12C27 — we cover it in detail in our 12C27 guide.
Against VG10 and AUS-10, the Japanese steels used across our own range, the picture flips. Both are typically run harder and carry a richer alloy mix, so they take and hold a finer edge for longer — the thing you notice most in a kitchen, where a knife is asked to slice cleanly rather than survive a rough day outdoors. The trade is that they take a little more work on a stone and are slightly less forgiving of abuse. Our VG10 guide and AUS-10 explainer go deeper on both.
Against powder steels such as S30V, 14C28N gives up meaningful edge retention but is far easier to bring back to sharp with ordinary equipment, and costs considerably less.
Is 14C28N good for kitchen knives?
Yes, with a caveat. Its corrosion resistance is excellent, which matters in a kitchen full of acidic food and washing-up water, and it sharpens back to keen very quickly — a real advantage if you are not confident on a stone yet.
The caveat is edge life. A kitchen knife spends its life making long, clean slices, and that is exactly where a harder, finer-grained steel earns its money. At the same skill level and the same care, a VG10 or AUS-10 blade will simply go longer between sharpenings.
So the honest answer is: if you find 14C28N in a knife you like at a price you like, buy it without worrying — it is proper steel, not a corner cut. If you are choosing a knife specifically on how long it stays sharp, look at the harder Japanese steels instead. And bear in mind that steel is only one variable; blade geometry, heat treatment and grind often matter more than the alloy name on the box.
Sharpening and caring for 14C28N
This is where 14C28N shines. It responds well to almost any method — a whetstone, a honing rod, or a guided sharpener — and it does not demand diamond abrasives the way high-vanadium powder steels do.
- Work through a coarse grit to raise a burr, then a finer grit to refine it. Our guide to feeling for a burr explains what you are aiming for.
- Because the steel is comparatively ductile, it can smear slightly rather than shear cleanly at very fine grits — a light pass on a fine or diamond rod cleans that up.
- Between sharpenings, a honing rod is enough. See whetstone vs honing steel for which to reach for and when.
- Stainless is not rust-proof. Dry the blade after washing rather than leaving it wet — the same rule that applies to any stainless kitchen knife.
What we actually stock
We don't sell 14C28N knives — our range is built on Japanese VG10 and AUS-10 steel, hardened to around 60–61 HRC. If what appealed to you about 14C28N was its rust resistance and easy upkeep, these are the closest kitchen equivalents with a longer-lasting edge.
Frequently asked questions
Is 14C28N a good knife steel?
Yes, for what it is: a nitrogen-alloyed stainless usually run at 58–62 HRC that sharpens easily and resists rust very well. It is a strong budget-to-mid steel, especially in folding and outdoor knives.
Is 14C28N better than VG10?
Not for edge retention. VG10 is typically run harder, at around 60–61 HRC, and holds a fine edge longer — which is what matters most in a kitchen. 14C28N is easier to sharpen and a little more forgiving in return.
Does 14C28N rust?
It is highly rust-resistant thanks to its 14% chromium and its nitrogen content, but stainless is never rust-proof. Dry it after washing and store it somewhere air can reach it, and it will stay clean.
What hardness is 14C28N?
Sandvik quotes a working range of roughly 55–62 HRC. Most knife makers heat treat it to somewhere around 58–62 HRC, choosing a lower figure for toughness or a higher one for edge retention.
Is 14C28N a powder-metallurgy steel?
No. It is conventionally melted and supplied as precision-rolled strip steel. That is a big part of why its carbides are so fine and even, and why it is one of the easiest stainless steels to sharpen.
Is 14C28N good for kitchen knives?
It works well and is very easy to maintain, but most Japanese-steel kitchen knives use VG10 or AUS-10 for a longer-lasting edge. Choose 14C28N if easy sharpening matters to you more than edge life.
