12C27 Steel vs 14C28N – What’s the Difference

12C27 steel vs 14C28N

When it comes to choosing the right steel grade for your knife, it can be a daunting task. With the various steel grades available in the market, choosing the right one that suits your needs takes work. Two popular steel grades that often come up in discussions amongst knife enthusiasts are 12C27 and 14C28N. Both are known for their corrosion resistance, easy sharpening, and excellent edge retention. In this post, we’ll delve deeper into the differences between the steel grades to help you decide which is right for you.

Difference Between 12C27 Steel and 14C28N


A significant difference between these two steel grades is their composition. 12C27 contains 0.60% carbon, 13.50% chromium, 0.40% manganese, and 0.10% nitrogen, while 14C28N contains 0.62% carbon, 14.00% chromium, 0.50% manganese, and 0.10% nitrogen. The higher carbon content in 14C28N makes it slightly less rust-resistant than 12C27 but also enables it to hold a sharper edge for longer.

Heat Treatment

Another difference between these two steel grades is their heat treatment. 14C28N undergoes a more advanced heat treatment process, which results in the formation of a finer grain structure. This makes 14C28N more durable and less prone to chipping and cracking than 12C27. However, the heat treatment makes 14C28N slightly harder to sharpen than 12C27.

Edge Retention

Edge retention refers to how long the blade’s sharpness can last without constant re-sharpening. As mentioned earlier, 14C28N has a higher carbon content than 12C27, which makes it hold a sharper edge for longer. This means that knives made from 14C28N require less maintenance and sharpening, making them ideal for everyday use.

Corrosion resistance

Both 12C27 and 14C28N steel grades are known for their corrosion resistance. However, 12C27 is slightly more rust-resistant than 14C28N due to its lower carbon content. 12C27 is a popular choice for knives and other outdoor tools exposed to harsh environments, such as humidity and saltwater.


In conclusion, 12C27 and 14C28N are excellent steel grades well-suited for knife making. The choice between the two steel grades comes from your specific needs and preferences. For those who require a blade that is highly resistant to rust and corrosion, 12C27 is an excellent choice, while those looking for a blade with superior edge retention might prefer 14C28N. Regardless of your choice, rest assured that both steel grades will perform well and offer good value for money. With the information in this post, we hope you can make an informed decision and enjoy the perfect knife for your needs.
