Details 9Cr18MoV Steel Review

What is 9Cr18MoV steel?

9Cr18MoV stainless steel is made in China from high carbon and chromium content. It has good corrosion resistance and hardness. Although it has a composition similar to AISI 440B, it has a more grainy texture because of the increased molybdenum-vanadium content.

This steel is used primarily to make stainless-steel knives, hunting knives and EDC knives (everyday Carry), surgical blades, pocket knifes, and cutlery.

9Cr18MoV Steel is a high-end Chinese stainless metal, but it is very affordable.

This steel knife is not considered low-quality, even though it costs less than high-end knives.

The 9Cr18MoV Steel has been used multiplely to make Damascus blades; Damascus 9Cr18MoV can be found in popular knives such as Civivi.

9Cr18MoV Steel Composition

  • Carbon 0.95%: Enhances edge retention, hardness, and tensile strengths. It increases steel resistance to wear and abrasion as well as corrosion.
  • Chromium Cro 18.50%: The use of Chromium increases the hardness, tensile strength, and corrosion resistance of a blade.
  • Molybdenum Mo 1.3%: Increases machinability, corrosion resistance.
  • Vanadium V 0.12% : This is vanadium carbide that forms hard vanadium in combination with other elements to improve wear resistance.
  • Manganese 0.80%: Increases steel’s strength and hardness. The steel’s hardenability can be improved by heating it.
  • Nickel Ni 0.65%: Increases strength and toughness. It can increase hardenability, but not as much than other alloying elements found in steel. It can increase corrosion resistance by significant amounts
  • Silicon Si 0.80%: Increases strength, heat resistance.
  • Phosphorus P 0.04: Increases hardness and machinability.
  • Sulfur S 0.03%: Increases machinability.

Properties 9Cr18MoV Steel

The 9Cr18MoV chemical formula listed above determines its properties. Let’s take a look at these.

9Cr18MoV Steel Hardness

9Cr18MoV’s Rockwell hardness is 58-60 HRC. The heat treatment can affect the hardness.

The steel’s hardness is due to its high carbon, Vanadium and Chromium content.

This level of hardness is high and will ensure that your knife lasts a long time.

9Cr18MoV steel Toughness

You should always sacrifice toughness for hardness in steel. 9Cr18MoV, being a hard steel, is therefore more brittle. This stainless steel knife is not recommended for extremely tough applications. It will easily chip and break. You should also look into Nitro V and MagnaCut steels.

To give the steel a decent toughness, however, manufacturers may add Nickel or Manganese to its 9Cr18MoV composition.

9Cr18MoV steel Edge preservation

This steel is harder than other steels and retains its sharpness for a longer time due to its hardness. It has excellent edge holding abilities due to the high levels of carbon vanadium (9Cr18MoV).

9Cr18MoV steel edges retain better than many popular steels like Nitro V, UUS 6 and UUS 8. However, it is lower than steels with a higher hardness such as CTS 204P and Maxamet.

9Cr18MoV steel Corrosion resistant

9Cr18MoV has enough Chromium to make it stainless steel. This means it is resistant to rust. This steel’s corrosion resistance is enhanced by the high levels molybdenum and nickel in its composition.

You can choose a 9Cr18MoV stainless knife if you need one to be used in moist areas with wet or salty material.

9Cr18MoV steel Wear resistance

Wear resistance of 9Cr18MoV Steel is excellent. Vanadium Carbide is formed from its composition. This greatly increases the blade’s hardness.

Sharpening 9Cr18MoV Steel

Sharpening 9Cr18MoV stainless steel is easy. It can be sharpened using common abrasive tools containing aluminum oxide. It will keep its sharpness for a long time so you won’t need to sharpen it as often.

Modern sharpening systems are a great option for those who don’t have much experience with knife sharpening. You will get a sharp edge on the knife steel in no time and will not need to resharpen.

9Cr18MoV-Steel comparison

9Cr18MoV vs. D2 steel

Both 9Cr18MoV and D2 steels are hard steels. However, D2 doesn’t contain enough Chromium so it isn’t considered stainless steel. D2 is considered semi-stainless; the chromium content of D2 is close to enough to make it stainless steel, but falls short. The 9Cr18MoV knife offers better resistance to corrosion.

While D2 steel is stronger than most stainless steels, it doesn’t have the same toughness as 9Cr18MoV blades. A 9Cr18MoV knife is more resistant to cracking and chipping than a D2 knife.

A D2 steel knife is more durable than a 9Cr18MoV knife in terms of edge retention and wear resistance. D2 steel is more hard than 9Cr18MoV and has a better edge retention and wear resistance. D2 steel can be used as tool steel. Its alloy provides incredible wear resistance.

9Cr18MoV in comparison to 440C

9Cr18MoV and 440C stainless are very similar. They share almost identical levels of Chromium and have nearly the same edge retention and corrosion resistance. Grade 440C has been called 9Cr18MoV equivalent. However, the true equivalent to 9Cr18MoV is AISI 440B.

They are also affordable, meaning you get high-quality blade steel at a fair price.

9Cr18MoV vs 8Cr13MoV

Both 9Cr18MoV and 8Cr13MoV are made from Chinese-made stainless steel. While 9Cr18MoV can be used as an equivalent of AISI 440B stainless steel, 8Cr13MoV can be used as an equivalent for Japanese AUS 8. 9Cr18MoV high carbon steel has more Carbon and more Chromium. This steel is more hardy and retains its edge better than 8Cr13MoV stainless.

Due to its high content of chromium in the alloy, 9Cr18MoV Steel has a better corrosion resistance than 8Cr13MoV Steel. An 8Cr13MoV Steel knife is more durable due to its lower hardness.

9Cr18MoV Vs VG10

Both 9Cr18MoV steel and VG10 are budget-made steels. VG10 steel is considered a premium Japanese steel, and 9Cr18MoV Chinese Steel.

An alloy of VG10 has more Vanadium and carbon elements. Combining more Vanadium with the carbon allows for the formation of Vanadium Carbides, which improve the hardness of VG10 steel over 9Cr18MoV.

Both are stainless steel but 9Cr18MoV has slightly better corrosion resistance than Takefu VG10 because it contains more chromium in its alloy. It contains about 3% more Chromium that the VG10 steel alloy.

You’ll get the same level of toughness regardless of which knife steel you choose, 9Cr18MoV or VG10.

However, Japanese-made VG10, which is made from 9Cr18MoV stainless steel, is more widely used than 9Cr18MoV and can be found in most knives.

9Cr18MoV vs. 14C28N

Sandvik 14C28N and 9Cr18MoV are two different types of steel. Due to their specific alloy composition, each steel has the best performance. Sandvik14C28N steel is among the most tough knife steels. Its toughness can be compared with that of AEB-l and 420HC steels. In terms of Toughness, it is far superior to 9Cr18MoV.

Corrosion resistance is another area in which Sandvik 14C28N stainless steel knife excels over 9Cr18MoV. 9Cr18MoV steel has more chromium elements that 14C28N steel. However, the alloy also contains Nitrogen, which significantly improves its resistance to corrosion and rust.

Sandvik 14C28N steel has a slightly lower edge retention, but a 9Cr18MoV Steel will provide slightly better edge retention. A Chinese-made steel is also cheaper.

A knife made from Sandvik 14C28N is more expensive than a 9Cr18MoV knife.

9Cr18MoV and 420HC

420HC stainless steel is an improvement of the old. This steel is a budget option that has high toughness and resistance to corrosion. The 420HC stainless-steel has the same corrosion resistance that 9Cr18MoV stainless. Both 9Cr18MoV stainless steel and 420HC are equally resistant to corrosion and rusting.

In Toughness, there is a significant difference between 9Cr18MoV stainless steel and 420HC. The 420HC stainless steel offers a high degree of toughness. Its toughness can be compared with that of AEB-L and 14C28N steel. The low Rockwell hardness of 56-58 HRC is responsible for the high Toughness.

A 9Cr18MoV knife will have better edge retention than an 420HC steel knife. This is due to its slightly higher hardness (58-60HRC). The 9Cr18MoV knife will be more resistant to wear and slightly harder to sharpen than the 420HC.

A 420HC steel knife is generally more efficient than a 9Cr18MoV knife.

9Cr18MoV vs. S30V

S30V stainless is considered premium steel while 9Cr18MoV is a more affordable option. The crucible industry produces S30V steel using the CPM process. This gives it a refined grain structure. S30V steel offers more balanced performance in terms of toughness, hardness, corrosion resistance and ease of sharpening.

A S30V steel knife will retain more edge edges than a 9Cr18MoV steel knife because it has a higher Vanadium content in its alloy.

Vanadium can be used to form hard vanadium carbides. This gives S30V steel high edge retention and wear resistance.

S30V steel is produced using the CPM process. It has a higher hardness than 9Cr18MoV and is more resistant to cracking and chipping than 9Cr18MoV.

9Cr18MoV stainless steel was made by adding large amounts of Chromium to its alloy at around 19%. A 9Cr18MoV knife made of stainless steel will have slightly higher corrosion resistance than an S30V knife.

10Cr15CoMoV vs 9cr18mov

10Cr15CoMoV Steel is a Chinese version of Japanese-made VG10steel. Its performance is therefore comparable to that of VG10 Steel. The alloy of 10Cr15CoMoV Stainless Steel contains more Vanadium, Carbon elements. Combining more Vanadium with carbon allows for the formation of Vanadium Carbides, which improve the hardness of 10Cr15CoMoV stainless steel over 9Cr18MoV.

Because 9Cr18MoV stainless steel has more Chromium than 10Cr15CoMoV, it will resist corrosion better. A 9Cr18MoV stainless steel knife can also be used outdoors for making hunting and fishing knives.

Both 9Cr18MoV and 10Cr15MoV Steel offer the same level of toughness. The two have little in common.

Their toughness is greater than super-hard steels such as S125V and 20CV. However, their toughness is lower than that of CPM M4, CPM3V and AUS 8.

Is 9Cr18MoV Steel good for knives?

It is a good knife steel, the answer is yes. We can confidently state that 9Cr18MoV is a great steel blade for knives by looking at its properties. It is a great choice for knives because of its high Hardness, excellent corrosion resistance and good edge retention.

The 58-60 HRC also gives this blade high wear resistance. Civivi Company is the most popular brand to use this knife. CJRB cutlery utilizes its proprietary powder AR-RPM9 Steel, which is considered an equivalent to 9Cr18MoV.

Conclusion

9Cr18MoV stainless is a great steel for knives, depending on what you need. If you have a limited budget and are looking for a premium knife, 9Cr18MoV stainless steel knife options will provide you with desirable features such as high corrosion resistance and excellent edge retention.
