Is 8Cr13MoV Good Knife Steel?

What is 8Cr13MoV Steel?

The 8Cr13MoV (commonly known as the China 13) is Steel produced in China. It belongs to the Cr13 steel series— which feature high carbon and high chromium elements. The perfect Steel for the money has gained popularity with this Steel and its variants.

The Japanese AUS-8 steel was used in the development of the 8Cr13MoV. Nevertheless, both sheets of Steel share the same characteristics because they are similar.

China produces a lot of Steel, including some for the kitchen. China also produces its variant of stainless Steel, called 8Cr13MoV. China’s Steel is often cheaper than American-made stainless Steel.

The China Cr13MoV has been developed with reference to the Japanese AUS-8 Steel, but with higher carbon content. This explains why both steels share similar characteristics: high quality at an affordable price point.

The China Cr13MoV is popular because it can be used in construction industry or as a material for other products that require corrosion resistance and toughness at low cost like cutlery, knives or utensils for use in high moisture environments such as kitchens where you might find yourself cutting up a tomato or other wet food item.

8cr13mov Chemical Composition

The chemical composition of this Steel is not well-defined because it is a unique alloy. However, the composition includes the following elements: a small quantity of chromium, molybdenum, sulfur, and nickel, vanadium, and a larger quantity of cobalt and manganese.

Elements Ratio%
Chromium 13.00 – 14.50
Carbon 0.7 – 0.8
Silicone <1.0
Manganese <1.0
Nickel <0.6
Phosphorous <0.04
Sulfur <0.04
Vanadium 0.10 – 0.25
Molybdenum 0.10 – 0.30

8Cr13Mov Steel Properties

8CR13Mov is a stainless steel that features high hardness with a Rockwell Hardness rating of 62HRC. It is an excellent choice for budget-conscious users because the blade steel is durable and sharp.

Edge Retention

One of the most exemplary aspects of this steel is that it has long edge retention. Edge retention is a term that refers to how long the blade of a knife or other cutting tool can maintain its sharpness. The edge will eventually wear down and be unable to cut effectively, so having good edge retention is important for knives.

Three major types of steel are used for knives: stainless steel, high-carbon steel, and low-carbon steel. With higher hardness, edge retention is also higher compared to mild carbon steel. One of the good things about this steel is that it offers you decent edge retention. This is because it’s made of higher hardness, which translates to better retention capabilities.

Wear Resistance

8Cr13Mov is a steel alloy that offers good wear resistance. Part of the composition of 8Cr13Mov includes Chromium and Vanadium, which give it this property. In addition, higher carbon in 8cr13mov blade steel content on quenching develops martensite in a structure that gives higher wear resistance.

The nucleation of carbides of chromium and Vanadium in the tempering stage also contributes to its wear resistance. As a result, 8Cr13Mov is an excellent choice for knives, tools, saws, chisels or other sharp objects with a high cutting action imposed on them by their use.

Corrosion Resistance

8Cr13Mov steel, which is made of stainless steel with more than 14% Chromium content, has exceptional Corrosion Resistance. The composition section shows that this steel contains a high percentage of chromium, which is crucial for keeping the steel free of oxidation and rusting. Stainless steels usually contain higher chromium content which prevents rusting or oxidation of Steel. The 8Cr13MoV steel contains a high amount of Chromium (Cr) and Molybdenum (Mo), making it highly corrosion resistant.

Weldability

8cr13mov high carbon stainless steel is not suggested for weldability.. This is because the Steel’s Carbon and Chromium concentration is higher, which means it is not suited for welding. If you are looking for a metal that can be easily welded, consider any alloy with less than 1% chromium such as 304 or 316 Stainless Steel, which has good weldability properties and is easy to work with bench grinder or lathe.

Sharpness

Why is 8Cr13MoV so easy to sharpen? Sharpening a knife isn’t just about being able to create an edge. It’s also about maintaining that edge over a period of time. In other words, it’s important for the steel that’s used in knives to be both hard and tough qualities usually associated with different types of steel. But what if you could have the best of both worlds? What if you could mix toughness with hardness and still maintain an optimal sharpness level? This is exactly what 8Cr13MoV offers. With less vanadium carbides, this type of steel will not only be easier to sharpen but also maintain its sharpness for longer periods meaning your blade stays sharper for much longer than other types of steel.

Toughness

The 8Cr13MoV is a tough steel that can endure a lot of usage before chipping or shattering. However, it would help if you were cautious about putting an 8Cr13MoV steel knife to excessive uses because it may not hold up. Instead, use it for basic cutting duties. It has a proper hardness, but for the price, it’s OK.

 

How Strong is 8Cr13MoV Steel?

8Cr13MoV steel is an alloy steel made of 14% chromium and 0.30% molybdenum. It has a Rockwell hardness between 57.6-62HRC, with 58+ being optimal. It’s used in applications where toughness is important, at least when compared to steels such as AISI 4140 or 8620 which are also common in the machining industry. Its Tensile Strength is 1315 MPA.

Is 8Cr13MoV Good Knife Steel?

8Cr13MoV is a low end budget steel, that offers decent edge retention, corrosion resistance, hardness and wear resistance. It’s an excellent steel for knife applications or an entry knife. From our 8cr13mov discussion above we can conclude that 8Cr13MoV steel is good for budget-minded users or an entry level knife user looking for something to use around the house or camping trips.

This Steel offers proper hardness, wear resistance, corrosion resistance and edge retention at a pocket friendly cost. But keep in mind you can get other high-end steels with superior edge retention, wear resistance and corrosion protection at higher price points. Still, these come with their own set of drawbacks like blade thicknesses being too thin which may break or cause issues when using.

Common Uses & Pros and Cons for 8cr13mov Steel

If you want a steel that can hold its edge longer, you may want to look at something like 440c. Instead, 8cr13mov is a much softer steel than most others. You may not be able to maintain the sharp edge at all times, as this makes sharpening it easier.

8CR13MOV is among many other steels used in blades meant for camping or hunting. It’s got some great qualities and drawbacks compared to higher quality steels and excels at what it was designed explicitly for -all-purpose use. So if you are looking for an affordable blade with the more premium feel of something like 440C but don’t need the extra endurance, it’s a great choice.

Common Uses:

8CR13MOV can find it in outdoor knives like hunting and folding knives, budget knives, outdoors/survival knives, EDC pocket knives, etc.

Pros:

  • Easy to maintain
  • It’s simple to sharpen
  • Corrosion resistance
  • More cost-effective

Cons:

  • It is not proof against rust or corrosion
  • Chromium content is required
  • Not really premium

8Cr13Mov Steel Comparison With other Steel

New Study on CATRA Testing of 8Cr13MoV

8Cr13Mov is currently leading the market for making blades. But if you are looking for its alternative I would say, the closest to 8Cr13Mov you could get is the AUS 8, another steel that comes from Japan. It has medium carbon levels and high chromium content. Thus say, the chemical properties of these two sheets of steel are pretty similar. The aus 8, like 8Cr13Mov also offers a nice sharp edge, excellent corrosion resistance, and decent toughness. In addition, both the steels are budget friendly and very good quality. So if you ask me what I’d choose for knife making, I’d go with the 8Cr13Mov (that’s a very personal preference).

8cr13mov vs 440c

The 8cr13mov steel contains higher carbon and chromium levels, which ranks it slightly higher in edge retention and resistance to corrosion than the 440C. As compared to 8Cr13MoV blade steel, 440C has a higher carbon (0.95-1.2%) and chromium content (16-18%). When it comes to hardness and edge retention, you may consider the 8Cr13MoV to be a step up model when compared to the 440c.

Attributes 440C 8CR13MOV
Toughness  5/10  6.7/10
Easy sharpening 7/10 8/10
Edge Retention

 

2.6/10 1.1/10
Corrosion Resistance 8/10 6/10

In the case of edge retention and corrosion resistance, 440c performs better than 8CR13MOV.

8cr13mov vs 8cr14mov

As the name implies, 8Cr14MoV has a somewhat higher chromium content than Chinese steel. And Both blades have very similar edge retention, toughness, and other characteristics in terms of performance. But 8CR14MOV has a bit more edge retention.

Attributes 8CR14MOV 8CR13MOV
Toughness  7/10  6.7/10
Easy sharpening 8/10 8/10
Edge Retention

 

2.5/10 1.1/10
Corrosion Resistance 6/10 6/10

 

To me, 8CR13MOV and 8CR14MOV are totally the same. They give similar performance.

8cr13mov vs VG10

8Cr13MoV steel has a higher carbon content, which makes it more wear resistant than VG10. It also has better toughness and edge retention. Vg10 compensates for this with better corrosion resistance and hardness. Due to its higher alloying content, while considering 8Cr13MoV vs. vg10, one must know that vg10 is more prone to chipping, so always go with 8CR13MOV steel for daily use.

Attributes VG10 8CR13MOV
Toughness  4.5/10  6.7/10
Easy sharpening 5/10 8/10
Edge Retention

 

6/10 1.1/10
Corrosion Resistance 6/10 7/10

VG10 has better edge retention, corrosion resistance than 8CR13MOV but lower toughness and ease of sharpening.

8cr13mov vs AUS 8

Aus8 and 8Cr13MoV are almost similar in carbon content. However, the former is Japanese grade steel having three times more molybdenum and vanadium than 8Cr13MoV. Aus8 is slightly better in edge retention and toughness as compared to the Chinese variant. While we are discussing Aus8 Vs8Cr13MoV, we must know that their purpose and quality are comparable. However, in a little detail, we can say Aus8 can take a bit more stress, and it can not retain edge as the Chinese variant. Chinese 8Cr13MoV high carbon stainless steel can keep a fine and sharp edge longer, but it is more prone to chipping if it hits a more rigid surface.

8cr13mov vs 7cr17mov

Chinese-produced budget knives are made from 8Cr13MoV and 7Cr17Mov. It’s not fantastic blade steel, and neither is it renowned. In my view, both are superior than 3Cr13, 5Cr15Mov, and other mystery steels that become more popular the lower you go. Both are known for being simple to sharpen. In theory, 8CR13MoV should be superior in terms of edge retention, but I’ve only had a few 7CR17Ms and many 8CR13MoVs, so I can’t say one way or the other.

8cr13mov vs 9cr18mov

9Cr is more hard and has better edge retention but less tough as compared to 8Cr13moV steel. The difference in carbon content, Chromium levels, as well as other properties make these two steels different for various applications.

Is d2 steel better than 8cr13mov?

D2 is higher-end steel compared to 8Cr13MoV. D2 tends to have more edge retention and hardness, but it’s also the more expensive of the two steels and less corrosion resistant than 8Cr13MoV. D2 is developed as tool steel while 8Cr13MoV is stainless steel with this in mind you expect D2 to have better cutting capabilities than 8CR13MOV. Sharpening D2 is also way easier than sharpening stainless steel because D2 has harder grains which are smaller so there’s less metal loss when grinding down D2, which means that you’ll need fewer strokes on your whetstone or oil stone before achieving a razor sharp edge.

Is 8Cr13MoV easy to sharpen?

It is convenient to sharpen it because of it’s 8cr13mov stainless steel hardness. The sharper the knife, the more useful it is as a cutting tool.

Does 8Cr13MoV steel rust?

When my Spyderco Tenacious was lost in my girlfriend’s back yard for a couple of months, it developed some surface rust and a few pits, so yes 8Cr13MoV can rust.

 

Conclusion:

So, I’ll be honest here. When I got to know about 8Cr13MoV, I didn’t have a very good first impression as it’s china made and very cheap. But this steel solely changed my perspective. Cheap doesn’t mean bad and this quote totally fits here? The 8Cr13MoV offers you significant aspects which are found in high-end steel. You will get good edge retention, corrosion and wear resistance, and hardness, but at a more affordable cost. So if you are looking for hard and tough entry-level or budget-friendly camping, hunting, or EDC knife, 8Cr13Mov steel blades are your answer. Happy slitting!
