440c Stainless Steel vs 420hc – What’s the Difference

440c Stainless Steel vs 420hc

When choosing the best steel for knives, 440c stainless steel and 420hc are the most popular options. While both steels are great for blades, they each have unique properties, making them better suited for different applications. In this post, we’ll look closer at the differences between 440c stainless steel and 420hc so you can make an informed choice when selecting the steel for your next knife.

Difference Between 440c Stainless Steel and 420hc


The primary difference between 440c stainless steel and 420hc is in their chemical composition. 440c contains about 1.2% carbon, 17% chromium, and 1% molybdenum, making it a high-carbon, high-chromium steel that is highly corrosion-resistant. 420hc, conversely, is a softer, more durable steel with lower amounts of carbon and chromium.


Another difference between these two steels is in their hardness. 440c is a harder, more brittle steel that is excellent for making precision blades that require a sharp edge and good retention. 420hc, on the other hand, is a less hard, more ductile steel better suited for knives requiring a bit more toughness and durability.

Corrosion Resistance:

Both 440c and 420hc are stainless steel resistant to rust and corrosion. However, 440c has a significantly higher resistance to corrosion due to its higher chromium content. If you are looking for a knife that can withstand exposure to harsh environments, 440c is the better choice.

Edge Retention:

One of the most important factors when choosing steel for a knife is how well it retains its edge. 440c excels in this area, retaining its sharp edge for longer than 420hc. However, 420hc is easier to sharpen and maintain, making it a great choice for knives subjected to heavy use.


Finally, there is the matter of price. 440c is a premium steel often used in high-end knives, which means it can be more expensive than 420hc. This is due to its superior performance and resistance to corrosion. 420hc, on the other hand, is a more affordable steel often used in mid-range knives.


When it comes down to it, the choice between 440c stainless steel and 420hc will depend on your preferences and the knife’s intended use. If you need a blade that can withstand exposure to harsh environments and retain its edge for longer, 440c is the better choice. If you need a more durable, easier-to-sharpen, and affordable knife, 420hc is the way to go. Whatever your choice, make sure to choose a reputable knife maker who uses high-quality steel and knows how to produce a blade that will serve you well for years.
