CPM S90V is a high-performance knife steel that has been gaining popularity recently. It is a premium steel that offers excellent edge retention, toughness, and corrosion resistance. In this article, we will take a closer look at CPM S90V and explore what makes it such a sought-after knife steel.

What is CPM S90V?

CPM S90V is a high-alloy, powder-metallurgy knife steel that was developed by Crucible Industries LLC. It is a member of the family of stainless steels that are specifically designed for use in high-performance cutting tools. CPM S90V is a complex steel that contains a high concentration of vanadium, which is responsible for its exceptional edge retention.

Edge Retention

One of the most impressive features of CPM S90V is its edge retention. This steel is known for holding an edge for an extended period, even under heavy use. This is due to the high concentration of vanadium, which forms very hard carbides that are resistant to wear. The carbides in CPM S90V are much smaller and more evenly distributed than those found in other steels, which helps to enhance its edge retention.

Toughness

CPM S90V is also known for its toughness, which is a measure of a steel’s ability to resist chipping and cracking. While CPM S90V is not as tough as some other steels, such as CPM 3V or Cru-Wear, it is still considered to be a highly durable steel. This is due in part to the steel’s high chromium content, which provides excellent corrosion resistance and helps to protect the steel from damage.

Corrosion Resistance

Another advantage of CPM S90V is its excellent corrosion resistance. This steel contains a high concentration of chromium, which forms a protective oxide layer on the surface of the steel. This layer helps to prevent rust and corrosion, which can be especially important for knives that are used in wet or humid environments. Additionally, CPM S90V is highly resistant to pitting and staining, which can be caused by exposure to acidic or corrosive substances.

Ease of Sharpening

While CPM S90V is an excellent choice for a knife steel, it can be more challenging to sharpen than other steels. This is due to the high concentration of vanadium carbides, which can make the steel very hard and resistant to abrasion. However, with the right equipment and technique, it is still possible to sharpen CPM S90V to a razor-sharp edge.

Applications

CPM S90V is a popular choice for high-end folding knives, fixed-blade knives, and other cutting tools. It is especially well-suited for knives that will be used for heavy-duty cutting tasks, such as hunting, camping, or survival. Additionally, CPM S90V is an excellent choice for knives that will be used in wet or humid environments, as its corrosion resistance helps to prevent rust and other forms of damage.

Conclusion

CPM S90V is an extremely hard steel that is popular among knife enthusiasts for its superior wear resistance, edge retention, and hardness. It is a relatively new steel but has quickly gained a reputation for being the ultimate choice for hard-use knives due to its superior performance. While CPM S90V is an excellent steel, it is important to remember that it can be difficult to sharpen and expensive to purchase.

For those looking for a superior cutting-edge, CPM S90V is an excellent choice, but it may not be the best option for everyone. With its superior performance and high cost, CPM S90V is an excellent choice for those with the tools and know-how to properly care for it.
