7Cr17MoV Steel Review: Properties, Composition, and Uses

What’s 7Cr17MoV stainless Steel?

7Cr17MoV Stainless steel is a modified steel grade 440A made in China. This steel is not of low quality. It has been modified with vanadium to increase its wear resistance and hardness.

7Cr17MoV stainless has been a leader in the production and sale of large chef knives, hunting knives, cleavers, survival knives, and hunting knives.

Knives made of 7Cr17MoV stainless are not only attractive, but also pocket-friendly and provide the best value for your money.

If you’re looking for a good-quality steel knife that won’t break the bank, 7Cr17MoV steel options are your best bet.

7Cr17MoV Steel Composition

  • Carbon 0.75%: Enhances edge retention, hardness and tensile strengths. It increases steel resistance to wear and abrasion as well as corrosion. 7Cr17MoV’s.7% carbon content is what gives it its distinctive name that starts with 7.
  • Chromium Cre 18.00%: 7Cr17MoV is “stainless” steel because it contains more than 11% Chromium. The hardness, tensile and toughness of the blade are increased by Chromium.
  • 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 Mn 0.80%: Increases steel’s strength and hardness. The steel’s hardenability can be improved by adding more manganese to it after it has been heat-treated.
  • 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 of 7Cr17MoV Steel

7Cr17MoV Steel Hardness

The hardness of 7Cr17MoV Steel is 60 HRC. This hardness is high according to Rockwell hardness ratings. CPM S30V, 8Cr13MoV and other common steels can match this Rockwell Hardness. 7Cr17MoV is a high-hardness steel, which is not like other low-end grades that offer low hardness.

High levels of carbon, vanadium and chromium are responsible for the 7Cr17MoV steel’s high hardness.

This will allow you to confidently carry your 7Cr17MoV knife outdoors for any type of outdoor application.

7Cr17MoV Stainless Steel Toughness

Although 7Cr17MoV steel is quite tough, there are more durable steels. Its toughness, though, is reasonable when compared to other low-end steels.

You cannot have both toughness and hardness in the steel world. The 7Cr17MoV steel’s hardness is excellent, so it is not surprising that there is some slackness in toughness.

7Cr17MoV steel Edge retention

It is good that 7Cr17MoV stainless can keep a sharp edge. Although you won’t have to sharpen it every day, we can’t brag about the knife’s edge retention abilities when compared with high-end knives.

It has high levels of vanadium and carbon, which increase its hardness and resistance to abrasion. However, it also contains sulfur as well as phosphorus. This steel is easy to fracture and break because of the high levels of sulfur and phosphorus. It has good edge retention. It is considered soft.

Knives made of 7Cr17MoV have decent edge retention, despite being affordable.

7Cr17MoV Stainless Steel Corrosion Resistance

The corrosion resistance test of 7Cr17MoV steel is passed with flying colors. This is due to the steel’s high content of chromium.

This makes knives made of this steel from China extremely versatile.

It can be used in the kitchen with moist ingredients, outdoors in the rain, and you don’t have to worry about corrosion, staining or rusting.

7Cr17MoV Steel Sharpness

Because 7Cr17MoV is a soft steel, sharpening it is quick and easy. With simple sharpening tools, 7Cr17MoV knives can be sharpened to razor-sharpness. It has a decent edge retention so you’ll need to sharpen it frequently.

However, 7Cr17MoV steel requires care. Avoid using a belt or machine to sharpen the blade as they are too abrasive.

7cr17MoV equivalent Steels

7Cr17MoV Vs 440A

7cr17MoV Chinese Stainless Steel is a modification to AISI 440A steel. This makes them very similar. 7Cr17MoV is equivalent to 440A.

The chemical composition of the two is identical, except that 7cr17MoV Steel has more vanadium. This makes it harder and more wear-resistant. The blade’s strength is increased by the addition of Vanadium.

7Cr17MoV vs 440C

7Cr17MoV stainless is a better knife steel than the 440C stainless steel for its corrosion resistance and ease in sharpening. In terms of edge retention, 7Cr17MoV blade stainless steel is superior to 440C. Both have an almost identical level in toughness.

In terms of corrosion resistance, 7Cr17MoV stainless Steel beats 440C. It has Nickel elements in its alloys, which significantly increase the resistance to corrosion and oxidation of steel when hardened at high temperatures.

Because it has a greater amount of carbon elements than 7Cr17MoV alloy, 440C blade steel provides better edge retention. This allows for the formation of more carbides than 7Cr17MoV.

Both 7Cr17Mov and AISI 440C offer similar levels of toughness. Most knives made with these types of steel will be equally tough. They are not as tough as 154CM Stainless Steel or premium.

Both steels can be easily sharpened with common abrasive instruments containing aluminum oxide.

7Cr17MoV 420HC

7Cr17MoV stainless Steel outperforms the 420HC stainless Steel in terms of corrosion resistance and edge retention. However, 7Cr17MoV stainless Steel is outperformed by 420HC stainless in toughness and ease-of-sharpening. The 420HC stainless-steel is a knife stainless steel that offers incredible toughness.

7Cr17MoV knife Steel is more resistant to corrosion than 420HC knife Steel. It contains 0.18% of chromium in its composition. 7Cr17MoV stainless steel has additional nickel elements, which is what 420HC knife-steel lacks.

7Cr17MoV blade Steel is marginally better than 420HC blade Steel in terms of edge retention. This is because it can achieve a higher Rockwell Hardness. Its high carbon content in its alloy composition is responsible for the higher Rockwell hardness than 420HC.

Latrobe 420HC stainless steel is superior to 7Cr17MoV and other blade steels in terms of toughness. The 420HC’s toughness is comparable with that of AEB-L stainless, 14C28N, and 3V steel. This makes 420HC an ideal choice for long blades, bushcraft knives and camp knives.

7Cr17MoV vs VG 10 Steel

7Cr17MoV blade stainless steel is more resistant to corrosion and easier to sharpen than Japanese VG 10. VG 10 stainless steel, on the other hand, has a better edge retention and toughness than Chinese 7Cr17MoV.

7Cr17MoV stainlesssteel is more resistant to corrosion than Japanese VG 10 stainlesssteel. It contains a high level of chromium element in its composition. This means that despite the formation chromium carbides some chromium element will still be present to enhance its stainless steel properties.

The Japanese VG 10 steel composition is designed to provide great hardness, edge retention and wear resistance, while maintaining stainless steel properties. This is due to VG 10’s greater Rockwell hardness than 7Cr17MoV, which gives it better edge retention.

VG10 steel is also more tough than 7Cr17MoV steel, despite having a higher Rockwell test. Its alloy composition, which includes more elements such as molybdenum or tungsten, can explain this.

VG10 steel is more wear-resistant than 7Cr17MoV. Sharpening a 7Cr17MoV stainless-steel knife is much simpler than sharpening a VG10 knife.

7Cr17MoV vs S30V Steel

Steel 7Cr17MoV has a better resistance to corrosion than steel S30V. CPM S30V stainless is a better knife steel than 7Cr17MoV. It is tougher, more durable, and has a better edge retention and wear resistance.

CPM S30V steel powder metalurgy process allows for extremely fine grain structure. This gives it a higher Rockwell hardness, and allows for the formation vanadium carbides which are crucial in edge retention.

Due to its high content of chromium in its alloy composition, 7Cr17MoV stainless Steel has a better corrosion resistance than S30V. 7Cr17MoV stainless steel blades will be more resistant to rust than S30V blades.

A 7Cr17MoV knife will be easier to sharpen than a S30V one, as it is slightly softer and doesn’t contain high amounts of Vanadium carbides. These vanadium carbides offer superior wear resistance.

7Cr17MoV vs. D2 steel

7Cr17MoV stainless steel is D2 steel, which is a non-stainless tool steel. Due to its low Rockwell hardness, 7Cr17MoV has a higher toughness than D2 steel blades. However, D2 steel is superior to 7Cr17MoV when it comes to edge retention and wear resistance.

D2 steel is a tool steel that offers excellent wear resistance and edge retention, in addition to other performance properties such as toughness and resistance to corrosion.

Both 7Cr17MoV and D2 blade steel have the same level of toughness. A 7Cr17MoV knife will be easier to sharpen.

You can find varieties of S35VN or S45VN from Crucible if you want a stainless-steel blade that has similar properties to D2 and better performance than 7Cr17MoV.

7Cr17MoV Vs AUS8

7Cr17MoV stainless is more resistant to corrosion and retains its edge better than Japanese AUS8 stainless steel. AUS 8 stainless is a stronger steel. Japanese AUS8 blade steel is twice as tough as 7Cr17MoV steel.

Budget steels include AUS 8 and 7Cr17MoV stainless. AUS 8 stainless is the preferred choice because of its exceptional toughness. Japanese AUS8 steel is more like 440B stainless steel, while 7Cr17MoV steel is a 440A equivalent.

Because of the lower Rockwell hardness, sharpening 7Cr17MoV stainless steel is easier than sharpening AUS 8.

7Cr17MoV vs 8Cr13MoV Steel

The main difference between 7Cr17MoV and 8Cr13MoV is that 7Cr17MoV steel has better corrosion resistance than 8Cr13MoV steel. 7Cr17MoV steel contains 17% chromium elements, compared to 13-14.5% in 8Cr13MoV Steel alloy.

Steel 8cr13mov has a better edge retention due to its higher carbon content, while steel 7Cr17MoV can be sharpened easily because it’s softer.

Due to its optimal balance of toughness and resistance to corrosion, 8Cr13MoV stainless is better than 7Cr17MoV. 8Cr13MoV stainlesssteel is a copy of Japanese 8 stainless steel.

7Cr17MoV 9Cr18MoV

High levels of corrosion resistance are demonstrated by both 7Cr17MoV as well as 9Cr18MoV steel. Both have a similar chemical composition with the only difference being the carbon content.

9Cr18MoV has a better edge retention and is therefore more difficult to sharpen. Because 9Cr18MoV has a higher wear resistance, sharpening it is more difficult than 7Cr17MoV.

7Cr17MoV Vs 7Cr17

7Cr17MoV as well as 7Cr17 are both low-end, budget stainless. Both are Chinese grades and provide a high price-performance ratio. The main difference is that 7Cr17MoV has Molybdenum, Vanadium elements which increase its wear resistance.

Is 7Cr17MoV stainless Steel good for knives?

7Cr17MoV stainless is a good choice for knives, especially if your budget is tight. The corrosion-resistant property makes 7Cr17MoV stainless Steel knives ideal for outdoor and indoor tough applications.

7Cr17MoV stainless will be found in most pocket knives, knife cases, knife holders, knife chefs, knife kitchens, knife survival, and budget knives.

Conclusion

7Cr17MoV stainless is Chinese steel. However, it is not as poor as you might think. A 7Cr17MoV stainless steel knife is easy to sharpen, maintain an edge, and resist corrosion.

Because Carbon steel can react to products that cause corrosion it is important to take good care of your 7Cr17MoV blade. Clean it, oil it, and dry it after each use.
