8Cr13MoV Steel Review: Properties, Composition, and Uses

How do I know 8Cr13MoV steel?

8Cr13MoV Stainless steel is a Chinese-made steel that is often viewed as a copy of AUS 8 steel from Japan. This can be described as Chromium Molybdenum stainless that is part of the CrMo/MoV range, similar to 8Cr14MoV stainless steel.

8Cr13MoV steel has a significant proportion of Carbon and Chromium elements. It’s a great quality, value-for-money Chinese steel, which is utilized by a variety of knife makers.

Chinese 8Cr13MoV stainless steel has gained lots of attention over the last few years due to its massive popularity among good quality Knife manufacturers like SpydercoKershaw, and SOG.

It is a very popular option by these manufacturers because of its superior steel properties and its affordable price point.

8Cr13MoV Steel Composition

Element Percentage composition Function
Carbon C 0.70%-0.80% Enhances edge retention, hardness and tensile force. Also, it improves resistance of steel in the face of wear, damage and corrosion.
Chromium Cr 13.00%-14.50% The process of forming Chromium carbide increases the strength, hardness and resistance to corrosion on the blade.
Nickel Ni 0.20% Increases the toughness of the blade. It enhances the resistance to corrosion and the oxidation rate at higher temperatures.
Molybdenum 0.10%-0.30% It increases machinability, toughness and resistance to corrosion.
Manganese Mn 1.00% Enhances the strength and toughness of the steel. If the steel is heated the hardenability of steel is enhanced due to more manganese.
Silicon Si 1.00% Strengthens and increases heat resistance.
Sulfur S 0.03% Improves machinability, but is seen as an impurity when in large amounts.
Phosphorus P 0.04% Increases machinability and hardness but is thought of as an impurity when present in large quantities.

8Cr13MoV Stainless Steel Mechanical Properties

8Cr13MoV Rockwell Hardness

8Cr13MoV steel has 8Cr13MoV Steel has a Rockwell the hardness of between 58 and 60 HRC. The degree of hardness depends on the heat treatment method and the tempering process employed.

You can attain high hardness by using this steel, however without sacrificing the toughness. The harder the steel is, the lower the degree of toughness.

If you use the correct 8Cr13MoV steel for heating treatment you will also create a very resistant to corrosion. The resistance to corrosion is influenced by heat treatment techniques as well.

8Cr13MoV Steel Edge Retention

8Cr13Mov stainless steel is a good edge retention. It is in the lower end of the spectrum of edge retention in knife steel. Edge retention is similar to AUS 8, LC200N, and Nitro V steel.

8Cr13MoV edge retention for knife steels is just half what other top knife steels such as S30V as well as M390 Steel provide.

Edge retention isn’t the most savage available as it is superior to 1.4116 steel and 420HC and a lot of low alloy steels, like 52100 and 8670 and so on.

8Cr13MoV steel knife can offer decent edge retention, sufficient to handle the everyday jobs. However, it needs to be sharpened regularly when it’s used to cut extremely abrasive objects like rubber pipings.

8Cr13MoV Stainless Steel Corrosion Resistance

8Cr13MoV stainless steel has excellent resistance to corrosion and rust because of its high percentage of Chromium.

Usually, when Chromium is greater than 11%, the steel is called “stainless steel”, which increases the steel’s resistance to rust and tarnishing.

8Cr13MoV steel’s rust resistance is higher than the other lower alloy steels for tools. In the stainless steel selection 8Cr13MoV has corrosion resistance similar to the high-end CPM S60V CPM the 154 and also Nitro V.

8Cr13MoV Steel Wear Resistance

The 8Cr13MoV stainless steel is able to stand up to wear quite because it has a significant amount of Carbon Manganese and Vanadium. These elements significantly impact the material’s resistance to wear.

Sharpening 8Cr13MoV Stainless Steel

Sharpening 8Cr13MoV steel is simple and can be accomplished with ordinary sharpening tools. It is easy to take the edge of a razor and maintain that same sharpness to allow for decent cutting.

With its good edge retention, you’ll not face any issues sharpening stainless steel 8Cr13MoV with aluminum oxide Abrasive tools.

8Cr13MoV Stainless Steel Toughness

Similar to other steels, it is impossible to achieve toughness and hardness with the same alloy, consequently, the strength of 8Cr13MoV can be a little low because of the very high Rockwell hardness.

The level of toughness of 8Cr13MoV stainless steel is comparable to the AUS8 as well as 26C3 stainless steel. The level of toughness is higher than that of the majority stainless steels available on the market, making 8Cr13MoV an extremely popular option for knife makers.

8Cr13MoV Steel in comparison to other steels

8Cr13MoV steel equivalent

AUS-8 steel is an Japanese kind of steel and 8Cr13MoV is manufactured in China. It is believed that both are made similar to each other. AUS-8 is slightly superior in edge retention and resistance to corrosion in the analysis of the characteristics, however their toughness is comparable.

8Cr13MoV vs S30V Steel

S30V steel is a superior in quality in comparison to 8Cr13MoV. S30V provides more edge retention when as compared to 8Cr13MoV because of its higher blend of carbon as well as its manufacturing process.

The problem is that CPM S30V’s sharpness is more difficult to sharpen and costly as compared to 8Cr13MoV. CPM S30V is not a favorite among most knifemakers with budget knives that require frequent sharpening.

CPM S30V steel has its excellent edge retention properties due to the large amount of vanadium carbides in the alloy composition.

S30V stainless steel’s powder metallurgy manufacturing process can also significantly increase its durability in comparison to other steels however, 8Cr13MoV steel that is budget-friendly is superior by a significant margin.

8Cr13MoV vs X50CrMoV15

The X50CrMoV15 steel has superior toughness than 8Cr13MoV steel however its Rockwell the hardness is 56HRC, which seems lower. 8Cr13MoV steel has more edge retention and harderness.

8Cr13MoV Steel X50CrMoV15 Steel
Toughness 6/10 2.5/10
Edge Retention 3/10 2.5/10
Corrosion Resistance 7/10 8/10

D2 vs 8Cr13MoV

8Cr13MoV is a stainless steel unlike D2 which doesn’t contain enough chromium that makes it stainless steel. This improves 8Cr13MoV’s the resistance to corrosion.

D2 steel, an instrument steel is superior to 8Cr13MoV steel for the area of edge retention as well as wear resistance. However, it offers lower toughness when compared to 8Cr13MoV stainless steel.

If you’re looking for a low-cost knife that has good corrosion resistance opt for an 8Cr13MoV knife. However, if you require a knife that has high edge retention and resistance to corrosion is not a problem, choose an Steel knife with D2.

8Cr13MoV Steel D2 Steel
Toughness 6/10 3.5/10
Edge Retention 3/10 5/10
Corrosion Resistance 7/10 4.5/10

8Cr13MoV vs 14C28N

Both Sandvik 14C28N as well as Chinese-made 8Cr13MoV knife are made of stainless steels with more than 13% chromium within their composition of alloys.

Sandvik 14C28N steel however it is more resistant to corrosion over stainless steel 8Cr13MoV thanks to the lower amount of impurities present in the alloy i.e Phosphorous and sulfur.

The lower impurities allow for the production of carbides which not only enhance the resistance to corrosion on the steel blade, but also enhance the strength of the blade.

Both 14C28N as well as 8Cr13MoV provide the same amount of Rockwell hardness. They also have the same durability and edge retention. The same edge retention when you use either the 14C28N stainless steel knife and an 8Cr13MoV Stainless knife.

Sandvik’s most recent research and development of 14C28N steel puts it the highest degree of toughness in knife steels.

14C28N steel’s toughness is superior to other stainless steel available It beats 8Cr13MoV stainless steel by offering nearly twice its strength.

14C28N’s toughness is similar to the 420HCAEB-L steelCPM 3V and surpasses the toughness that of M390 premium, 20CV and CTS 204P..

There are only a handful of steels that have the ability to surpass 14C28N steel’s toughness. These include the 8670 steel5160 steel and Z-Tuff Steel.

8Cr13MoV Steel 14C28N Steel
Toughness 6/10 9/10
Edge Retention 3/10 3/10
Corrosion Resistance 7/10 8.5/10

Is 8Cr13MoV Good knife steel?

8Cr13MoV knife is an excellent budget option for a knife. It’s decent quality steel that offers an excellent balance of edge retention, the ease of sharpening, and cost.

But, in comparison to more expensive steels like that of the S30V steel, the 8Cr13Mov may be a bit more susceptible to brittleness and corrosion. The best option under the guidance of the Chinese manufacturers is that of the 9Cr18MoVseries.
