What Is MagnaCut Steel: The Newest Super Steel from Crucible

MagnaCut steel has gained massive recognition in the world of high-performance materials, particularly in the knife-making industry. As an advanced stainless steel alloy, MagnaCut boasts a unique combination of properties. Developed by Larrin Thomas at Knife Steel Nerds, it has quickly become a popular choice for many knife enthusiasts.

The well-balanced characteristics of MagnaCut have proven advantageous for various cutting tools. It is considered a must-try for those seeking a high-quality option. Without further ado, let’s take a closer look at its performance below.

MagnaCut steel overview


The primary makeup of MagnaCut steel includes iron, carbon, chromium, molybdenum, nitrogen, etc. The combination of these elements forms a steel that exhibits high corrosion resistance, exceptional edge retention, and great toughness. This ensures that your MagnaCut steel tools and knives remain durable and reliable even in harsh environments. Here is a list of its composition:

  • Carbon: 1.15%
  • Chromium: 10.70%
  • Molybdenum: 2.00%
  • Vanadium: 4.00%
  • Manganese: 0.50%
  • Nitrogen: 0.20%
  • Niobium: 2.00%
  • Silicon: 0.40%

Magnacut steel boasts a unique and innovative composition that sets it apart from traditional steel alloys. One of its key components is nitrogen.

Nitrogen is known for its ability to improve hardness and wear resistance, making Magnacut steel exceptionally durable and long-lasting. This ensures that the blades made from this steel can retain their sharpness for extended periods, making them ideal for heavy-duty cutting tasks.

Additionally, Magnacut steel incorporates niobium, a rare and valuable element, which further contributes to its exceptional properties. Niobium strengthens the steel’s grain structure, enhancing its toughness and resistance to deformation, allowing the blades to withstand substantial mechanical stress without compromising their integrity.

History and development

history and development of magnacut steel

Developed in 2021, MagnaCut Steel is a product of Crucible Industries, a renowned American company that has been at the forefront of producing high-quality, specialty steel products. Their collaboration with Larrin led to the birth of CPM MagnaCut, which continues to garner recognition for its performance and versatility.

Through a series of trial-and-error, numerous prototypes were tested for the ideal blend of elements, experimenting with different levels of chromium, vanadium, nitrogen, and tungsten. The final result was Magnacut steel, boasting a remarkable synthesis of performance traits that make it distinct from other stainless steels.

The successful creation of Magnacut steel demonstrates how precision-engineered stainless steel can offer impressive qualities, making it an ideal choice for a wide range of cutting tools. Its versatility and unparalleled performance are quickly earning it a reputation as a game-changer in the industry.

As you explore its potential, you may find that Magnacut steel is the perfect choice for your investment.

Characteristics of MagnaCut steel


MagnaCut steel is known for its high hardness levels, enabling an incredibly sharp edge. Generally, you’ll find that MagnaCut steel has a Rockwell hardness of around 62 HRC with proper heat treatment, which makes it ideal for making most survival knives and high-class cutlery knives.

Corrosion resistance

One of the most notable features of MagnaCut steel is its exceptional corrosion resistance. This material is designed to withstand harsh environments and exposure to moisture, salt, and other corrosive elements. As a result, your MagnaCut steel tools and knives will require less maintenance and remain in better condition for a longer period.

Edge retention

Another critical aspect of MagnaCut steel is its outstanding edge retention. Due to its optimal balance of hardness and toughness, this steel can hold a sharp edge for an extended timeframe. In practice, this means you’ll spend less time sharpening your MagnaCut steel blade and more time using it efficiently.


The toughness of MagnaCut steel is not compromised by its excellent hardness and corrosion resistance. It maintains a remarkable balance between these characteristics and toughness – the ability to resist chipping, breaking or fracturing under pressure or impact. MagnaCut even outperforms most industry-leading super steels such as M390, S35VN, etc. This resilience allows you to use MagnaCut steel in various applications without worrying about damaging the material.


Although MagnaCut steel is known for its edge retention, you will still need to sharpen it occasionally. Fortunately, this material is not overly challenging to sharpen. With the proper sharpening technique and equipment, you can easily maintain and prolong the sharpness of your MagnaCut steel tools and knives.

Comparison to other steels

When comparing MagnaCut steel to other types of steels, you’ll find that it holds some advantages over both stainless and non-stainless steels. Let’s take a closer look at these differences.

Stainless steel

MagnaCut steel outperforms many stainless steels in terms of corrosion resistance. It is designed to resist rust even in harsh environments, making it an ideal choice for outdoor applications. When compared to popular stainless steels like VG10, MagnaCut offers superior edge retention and is less prone to chipping. This makes your tools and knives more durable and longer-lasting.

Higher-End CPM steel

MagnaCut steel is often compared to higher-end CPM steels—such as CPM-20CV, CPM-S110V, and CPM-S90V—due to its exceptional performance. It exhibits much better edge retention and toughness, while also excelling in corrosion resistance. This makes MagnaCut a competitive option among premium steels, despite being a newer entry in the market.

In summary, MagnaCut steel offers a superior combination of edge retention, toughness, and corrosion resistance, making it an attractive choice when compared to other steel. Its performance also stands up well against higher-end CPM steels, further solidifying its position as a versatile and robust option for various applications.

Should you invest in MagnaCut steel?

MagnaCut steel is the true definition of super steel. Its corrosion resistance and toughness are among the best even within powdered steel. Not to mention the impressive hardness, edge retention, and wear resistance. This combination of characteristics makes it highly sought after in various industries, including cutlery, outdoor gear, and components for industrial machinery.
