440 Stainless Steel vs 8Cr13MoV

When choosing the right knife, there are many things to consider. The blade material is an essential factor in deciding its quality and performance. Two popular types of steel used in knife-making are 440 stainless steel and 8Cr13MoV. Although they might look similar on the surface, there are some significant differences between them. In this article, we will discuss the difference between 440 stainless steel and 8Cr13MoV and the advantages and disadvantages of each.

Difference Between 440 Stainless Steel and 8Cr13MoV


440 stainless steel contains 17% chromium and 0.2% carbon, making it stainless steel. Its hardness ranges from 55-58 HRC, and it has moderate durability. On the other hand, 8Cr13MoV contains 13% chromium, 0.8% carbon, and 0.2% molybdenum, making it higher-quality stainless steel. Its hardness ranges from 56-59 HRC and is highly durable. Therefore, 8Cr13MoV is generally considered to be better steel than 440.


Both 440 and 8Cr13MoV hold an edge quite well and are relatively easy to sharpen. However, 8Cr13MoV has a better retention capability, meaning it will maintain its edge for longer than 440. This significant advantage makes 8Cr13MoV a preferred choice for many knife enthusiasts.

Corrosion Resistance

As 440 stainless steel is stainless steel, it has good corrosion resistance but is not as good as 8Cr13MoV. 8Cr14MoV has a higher chromium content, which provides excellent resistance to corrosion and oxidation, particularly in humid and marine environments. Therefore, 8Cr13MoV is a better option if you require a knife for outdoor activities where humidity is high or there is exposure to saltwater.


One advantage of 440 stainless steel is that it is relatively affordable, making it an excellent choice for entry-level knives or people on a budget. However, since 8Cr13MoV is considered higher quality steel, knives made from this material will generally be more expensive.


In conclusion, 440 stainless steel and 8Cr13MoV are good options for knife-making, but each has unique advantages and disadvantages. If you’re looking for a budget-friendly option with moderate durability, 440 stainless steel is a good choice. However, if you’re looking for higher durability and better corrosion resistance, 8Cr13MoV is the way to go. Ultimately, the selection of the blade steel depends on your intended use for the knife, your budget, and your personal preference.
