Choosing the perfect knife steel can be a daunting task, especially when faced with popular options like 9Cr18MoV and 14C28N. Both steels boast impressive qualities, but how do they truly stack up against each other? Whether you’re a metalworker, knife enthusiast, or industrial professional, understanding the nuances of these materials is crucial. From chemical composition and hardness to edge retention and corrosion resistance, each steel has its own strengths and weaknesses. So, which one should you trust for your next knife-making project? Let’s dive into the detailed comparison of 9Cr18MoV and 14C28N to uncover which steel reigns supreme.
9Cr18MoV is a type of stainless steel that is very durable and resistant to corrosion. Its composition includes:
14C28N, a Swedish stainless steel, is favored for its balance between hardness and toughness. Its composition includes:
With 1.40% carbon, 14C28N is harder and retains its edge better than 9Cr18MoV, which has 0.95% carbon.
With 18.50% chromium, 9Cr18MoV offers better corrosion resistance than 14C28N, which has 14% chromium, especially in humid environments.
9Cr18MoV includes more molybdenum (1.30%) than 14C28N (0.11%), making it stronger and more resistant to pitting.
Both steels contain silicon and manganese, contributing to their toughness and strength. However, 9Cr18MoV has higher silicon (0.80%) and manganese (0.80%) levels compared to 14C28N (0.30% and 0.50%, respectively).
14C28N has higher nitrogen content (0.75%) than 9Cr18MoV (0.60%), which enhances its hardness and corrosion resistance.
9Cr18MoV includes vanadium (0.12%), which is absent in 14C28N. Vanadium significantly boosts wear resistance in 9Cr18MoV.
The primary differences in the chemical composition of 9Cr18MoV and 14C28N are:
Both 9Cr18MoV and 14C28N steels are highly regarded for their hardness, which is crucial for cutting tools and knives.
9Cr18MoV can achieve a Rockwell hardness of 58-60 HRC, largely due to its carbon content and the formation of vanadium carbides, which enhance the steel’s overall hardness and edge retention. This makes 9Cr18MoV highly effective for applications requiring a sharp and durable cutting edge, such as high-performance knives and precision cutting tools.
14C28N typically achieves a Rockwell hardness of 55-58 HRC, thanks to its higher carbon and nitrogen content. This composition boosts its hardness, making it a strong contender in the budget-friendly knife segment. While it does not reach the maximum hardness levels of 9Cr18MoV, 14C28N provides a good balance of hardness and toughness, suitable for a wide range of knife applications.
Performance in steel is measured by a combination of factors including edge retention, ease of sharpening, and overall toughness.
9Cr18MoV is known for its excellent edge retention, maintaining sharpness over extended use due to its high carbon content and vanadium carbides. While 14C28N also offers good edge retention, it doesn’t match the prolonged sharpness of 9Cr18MoV but performs well for everyday use.
Despite its hardness, 9Cr18MoV is relatively easier to sharpen compared to some other high-end steels. This is attributed to its balanced composition, which allows for efficient sharpening without compromising on edge retention. Its slightly lower hardness makes 14C28N easier to sharpen, allowing users to quickly restore the edge.
9Cr18MoV offers decent toughness, balancing hardness and resilience. The presence of elements like nickel and manganese helps in maintaining toughness, reducing the risk of chipping under stress. 14C28N provides a good level of toughness, making it suitable for a variety of applications.

Proper heat treatment further enhances these qualities, ensuring the blade remains sharp for longer periods.
14C28N steel is known for its good edge retention, which is highly valued in high-quality knife applications. The steel’s composition features a higher carbon content (1.40%) and the addition of nitrogen (0.75%). The carbon increases hardness, and the nitrogen further boosts hardness without compromising toughness, aiding in edge retention. Proper heat treatment can bring the hardness of 14C28N up to 62 HRC, which is beneficial for maintaining sharpness.
When comparing the edge retention of 9Cr18MoV and 14C28N, both steels demonstrate strong performance, but there are notable differences. While both steels offer strong edge retention, 14C28N has a slight advantage due to its higher carbon and nitrogen content, which enhance hardness and sharpness.
Choose 9Cr18MoV for a budget-friendly option with good edge retention and excellent corrosion resistance. It is suitable for general use and environments where rust resistance is critical. Opt for 14C28N if you need a high-end knife that stays sharp longer and is very durable, making it an excellent choice for demanding applications requiring a consistently sharp blade.
9Cr18MoV steel stands out for its exceptional corrosion resistance, thanks to its high chromium (18.50%) and molybdenum (1.30%) content. Chromium creates a protective layer on the steel’s surface, preventing rust and oxidation. Molybdenum boosts this resistance by preventing pitting and crevice corrosion, common in environments with chlorides and other corrosive agents. This combination makes 9Cr18MoV particularly suitable for harsh environments where the steel is frequently exposed to moisture, chemicals, and saltwater.
14C28N steel also offers excellent corrosion resistance through a different composition. It contains 14% chromium and a significant amount of nitrogen (0.75%). The presence of nitrogen, in addition to chromium, helps form a stable passive layer that prevents rust and maintains the integrity of the steel in humid and wet conditions. This makes 14C28N perfect for everyday use. It handles varying environmental conditions well but isn’t designed for extremely corrosive environments.
