What is different between VG10 and AUS10?

VG10 and AUS10 are both popular types of stainless steel used in the production of high-quality knives. While they share some similarities, there are a few key differences between them:

  1. Composition: VG10 is a Japanese stainless steel with a high carbon content, typically around 1%. It also contains elements like vanadium, molybdenum, and cobalt, which contribute to its exceptional hardness and edge retention. On the other hand, AUS10 is a Japanese stainless steel with a slightly lower carbon content, usually around 0.95%. It also contains elements like vanadium, which enhance its hardness and corrosion resistance.
  2. Hardness: VG10 is known for its excellent hardness, typically ranging between 59-61 HRC (Rockwell hardness scale). This hardness allows it to maintain a sharp edge for extended periods and makes it suitable for precision cutting tasks. AUS10 has a slightly lower hardness, typically falling between 58-60 HRC, but it still provides good edge retention and cutting performance.
  3. Corrosion Resistance: Both VG10 and AUS10 exhibit good corrosion resistance, thanks to their high chromium content. However, VG10 generally offers better resistance to corrosion and staining compared to AUS10, making it a preferred choice in humid or acidic environments.
  4. Price: VG10 is often considered a higher-end steel and is associated with premium knife brands, which can reflect in its price. AUS10, while still a quality steel, is generally more affordable and offers good performance for its price point.

Ultimately, the choice between VG10 and AUS10 depends on your specific needs and preferences. If you prioritize exceptional hardness and edge retention, VG10 may be the preferred option. If you’re looking for a balance between performance and affordability, AUS10 can be a suitable choice. It’s recommended to try knives made from both steels to determine which one best suits your requirements.
