440c Stainless Steel vs S30V – What’s the Difference

440c Stainless Steel vs S30V

When choosing a high-quality stainless steel for your knife blade, many options are available in the market. Two popular options are the 440c stainless steel and S30V steel. In this blog post, we’ll take a closer look at the differences between the two to help you make an informed decision when purchasing your next knife.

Difference Between 440c Stainless Steel vs S30V


440c stainless steel is a high-carbon and chromium stainless steel that is corrosion-resistant and relatively durable. It comprises 17% chromium, 0.95% carbon, 1.2% manganese, 1% silicon, and 0.75% molybdenum. On the other hand, S30V steel is a high-performance powder steel that features a combination of carbon, chromium, and vanadium. It contains 1.45% carbon, 14% chromium, 2% vanadium, 0.5% molybdenum, and 0.5% niobium.

Hardness and Toughness:

440c steel is known for its toughness and durability. It has a hardness of 58 to 60 HRC, which means it is relatively hard and can hold a sharp edge for a long time. However, it is easier than other steels and can chip or break under high stress. In contrast, S30V steel is much tougher than 440c steel, with a 58 to 60 HRC hardness. It offers excellent edge retention and can withstand high stress without chipping or breaking.

Corrosion Resistance:

Both 440c stainless steel and S30V steel are corrosion-resistant, but S30V is more resistant to rust and corrosion than 440c steel. This is due to the high concentration of chromium and vanadium in S30V steel, which makes it less susceptible to corrosion, staining, and pitting.


440c stainless steel is easy to sharpen and maintain, making it a popular choice for novice knife collectors. It sharpens relatively quickly and holds a sharp edge for a long time. However, S30V steel is more challenging to sharpen due to its hardness. It requires a special sharpening stone, which may take longer than a 440c blade.


Price is an important factor to consider when choosing a stainless steel for your knife blade. 440c stainless steel is generally more affordable than S30V steel due to its lower production cost and popularity. On the other hand, S30V steel is a premium steel and often comes at a significantly higher cost.


Choosing the right stainless steel for your knife blade depends on your preferences and intended use. If you want an affordable, durable, easy-to-maintain blade that holds a sharp edge for a long time, 440c stainless steel can be a great choice. On the other hand, if you need a high-performance blade that can withstand high stress and resist corrosion, S30V steel is the way to go. Choose a reputable manufacturer to ensure you’re getting a quality product that will last.
