80CrV2 Knife Steel Bar--Equivalent to European standard 1.2235 and AISI L2 in the U.S.
80CrV2 is a blade-grade tool steel featuring an optimized composition of 0.75%–0.85% carbon, 1.00%–1.30% chromium, and 0.15%–0.30% vanadium. Refined through Electro-Slag Remelting (ESR), sulfur content is controlled to ≤ 0.005%, resulting in uniformly distributed carbide particles (≤ 8 μm). Its key performance attributes include:
Heat Treatment Properties
Quenching temperature: 820–860°C
Tempering temperature: 150–200°C
Surface hardness: Up to HRC 58–61
Core toughness: Impact strength of 40–50 J/cm²
Wear Resistance
Archimedes wear test: ≤ 0.015 g per 1000 cycles under 50 N load
Delivers 3× longer wear life compared to conventional carbon tool steels
Machining Advantages
Annealed hardness: ≤ 229 HB
Machinability index: Up to 65% (with 45# steel as 100%)
Supports high-precision grinding (surface roughness Ra ≤ 0.4 μm)

Products feature
1. High wear resistance: The 1.2235 tool steel bar is known for its excellent wear resistance, making it ideal for tough and demanding applications. This characteristic ensures that the tool maintains its edge for a long time, allowing for efficient cutting and shaping.
2. Good toughness: The 80crv2 steel used in the production of the 1.2235 tool steel bar possesses good toughness, which means that it can withstand the application of forces without fracturing or breaking. This enhances the durability of the tool, reducing the need for constant replacements.
3. Excellent edge retention: The 1.2235 tool steel bar is also known for its ability to maintain its edge for an extended period. This feature is crucial in applications such as cutting, where a sharp edge is needed to achieve precise and accurate cuts.
4. Corrosion resistance: The production process of the 1.2235 tool steel bar includes the addition of elements such as chromium, which increases its resistance to corrosion. This feature is essential, especially in applications where the tool is exposed to harsh environments.
5. Versatility: The 1.2235 tool steel bar is versatile and can be used in a wide range of applications, including the manufacture of cutting tools, machinery components, and even surgical instruments.

FAQ
Q: Why would I choose 80CrV2 over a plain 1095 carbon steel for a blade?
A: Because it holds a working edge longer without becoming brittle. The chromium and vanadium add wear resistance, while the ESR refining makes the carbides much finer – so you get less micro‑chipping when you sharpen. 1095 is cheaper, but you'll resharpen it more often.
Q: Does the ESR actually make a noticeable difference in grinding and polishing?
A: Yes,especially in the finish. The fine carbide distribution (≤8μm) means fewer hard spots, so your grinding belts last longer and you can get a mirror polish with less effort. We've had makers tell us they cut finishing time by about 20% compared to conventional melts.
Q: What's the trick to heat‑treating this steel without warping a thin blade?
A: Quench at 820–860°C, then temper immediately at 150–200°C. The key is slow, even heating and a press quench if you can. Because the material is air‑hardening to some extent, you don't need a fast oil quench – that's what keeps distortion low. We supply it in the annealed condition at ≤229HB, so you can grind your profile before hardening.
Q: Is 80CrV2 corrosion‑resistant enough for a hunting knife that sees rain and blood?
A: It has about 0.5% chromium, which gives some rust resistance but not stainless levels. For outdoor use, you'll want a coating or a forced patina. That said, we've shipped to several knife brands that use it for bushcraft blades – they just oil the blade after use. If you need true stainless, we'd point you to something like 14C28N.
Q: Do you only sell annealed bars, or can I get it pre‑hardened and tempered?
A: We mainly stock annealed because most of our customers grind their own bevels before hardening. But if you need pre‑hardened, we can arrange heat treatment on request – 58–60 HRC, with a straightness check and tempering. Lead time for that is about a week longer, and we charge by the kilogram for the treatment.
Q: I'm making a batch of chef's knives – how consistent is the hardness from one bar to the next?
A: Very consistent, because we control the melt and ESR process in‑house. Every bar comes with a mill test report that includes actual hardness and impact values. For production runs, we can even segregate bars from the same heat to eliminate any variation. We've supplied to several cutlery factories that do zero hardness testing on incoming material – they trust our MTC.
