8Cr13MoV is equivalent to Japanese AUS-8 steel.
They share nearly identical chemical compositions and performance characteristics. Both are highly popular budget-grade stainless steels.
The Closest Equivalents
AUS-8 (Japan): This is the most direct equivalent. It holds an edge and sharpens almost identically to 8Cr13MoV. Many knife enthusiasts consider AUS-8 slightly better only because Japanese manufacturing plants historically maintained stricter quality control and heat-treating standards.
440B (USA): In terms of carbon and chromium content, 8Cr13MoV sits comfortably between American 440A and 440B steels, though it performs closest to 440B. However, 8Cr13MoV includes vanadium, which gives it a finer grain structure and better toughness than the standard 440 series.
Chemical Composition Breakdown
To see how close they are, look at how their key elements match up:
Steel Type | Carbon (Edge Retention) | Chromium (Rust Resistance) | Vanadium (Toughness) |
|---|---|---|---|
8Cr13MoV | 0.80% | 13.00% – 14.50% | 0.10% – 0.25% |
AUS-8 | 0.70% – 0.75% | 13.00% – 14.50% | 0.10% – 0.26% |
Because 8Cr13MoV has a fraction more carbon, it can technically be hardened slightly more than AUS-8, but in real-world daily use, you will not notice a difference in how they cut, rust, or sharpen.
