8Cr13MoV is a Chinese high-carbon martensitic stainless steel that has become one of the most popular "value" steels in the global knife industry.
It is widely considered the Chinese equivalent to the Japanese AUS-8 steel, offering a very similar performance profile at a lower production cost.
Key Characteristics
Best-in-Class Value: It offers an excellent balance of performance for its price. This is why famous brands like Spyderco (Tenacious line), Kershaw, and CRKT use it for their entry-level flagship models.
Decent Edge Retention: Typically hardened to 57–59 HRC, it holds an edge significantly better than the 420 series or 440A, though it falls behind mid-range steels like 14C28N.
Extremely Easy to Sharpen: One of its best traits is how quickly it takes a razor-sharp edge. Even with basic sharpening tools, you can get it back to hair-shaving sharpness in minutes.
Good Toughness: It is a stable steel that resists chipping well during daily tasks like cutting cardboard, rope, or wood.
Average Corrosion Resistance: With 13% Chromium, it is stainless, but it is more prone to spotting than 440C or 14C28N if left in humid conditions or not wiped down after use.
Chemical Composition
The name 8Cr13MoV describes its recipe:
Carbon (C): ~0.80% (Provides good hardness and wear resistance)
Chromium (Cr): 13.00% (The minimum threshold for stainless steel)
Molybdenum (Mo): Increases strength and hardenability.
Vanadium (V): Increases toughness and refines the grain for a keener edge.
Common Applications
Budget EDC (Everyday Carry) Knives: Most notably the Spyderco Tenacious and various Kershaw speed-safe folders.
Multitools: Often used for the primary blade in budget-friendly multi-tools.
Mass-market Kitchen Knives: Popular for household sets that prioritize ease of sharpening.
