How Good is CPM 3V steel? Details CPM 3V steel review

CPM 3V Steel is tool with high carbon steel made by crucible industries, based on Crucible Powder Metallurgy Technology.

It is laudable for its exceptional hardness and wear resistance and is classified in the same category as the other steels used in tooling belonging to Crucible Killer-V’s, which includes CPM 3V CPM 9, CPM 10VCPM 15V and CPM M4.

Its characteristics make it ideal to make stamping tools, dies knifes, scrap choppers punches and shearing blades among others.

The knife business, it’s utilized to produce large blades, swords, or fixed blade knives as a result of their superior capability to resist breaking and chipping when subjected to the rigors of work.

It is important to note it is important to note that CPM 3V does not qualify as stainless steel since it doesn’t have enough chrome to make it a stainless steel.

CPM 3V steel composition

  • Carbon C 0.80 percent: Enhances strength, edge retention, and tensile force. It also increases steel resistance against wear, scratching, and corrosion.
  • Chromium Cr 7.50%: Formation Chromium carbide that increases hardness and tensile strength, as well as the resistance to corrosion of the blade.
  • Molybdenum Mo 1.30 percent This improves machinability as well as hardness.
  • Vanadium V 3.00 percent: Improve durability and wear resistance and also enhances the resistance to corrosion.
  • Tungsten W 0.40 percent Improves the wear resistance and hardness. typically used in conjunction with tool steel.
  • Manganese Manganese 0.40 percent: Increases hardness and brittleness.
  • Silicon Si 0.90 percent: Increases strength and resistance to heat.
  • Phosphorous P 0.03 percent: Increases steel’s strength and resistance corrosion. However, it is generally considered harmful when used in large quantities.
  • Sulfur S 0.03 percent: Sulphur increases its machinability, however it is usually thought of as an impurity, and is therefore added in small amounts.

CPM 3V steel properties

CPM 3V Steel Hardness

CPM 3V steel’s toughness is 58-60 HRC according to the Rockwell hardness scale. This range of hardness is ideal for knives made of steel.

But, the steel is able to be able to achieve a higher degree of hardness up 64 HRC subject to process of heat treatment.

It is important to note that toughness decreases with this kind of hardness. Many steels can offer great hardness but at the expense of toughness, but this is this is not the case with CPM 3V stainless steel.

CPM 3V Steel Toughness

The capability to stand up to breakage and chipping is crucial in determining if steel is appropriate for making knives.

CPM 3V has a high degree of toughness It is certain that knives made from CPM 3V will not break due to collisions from hard applications such as cutting or batoning.

CPM 3V steel Wear resistance

Another aspect that is unique to Steel is the wear-resistant that was first linked to the CPM production process.

Furthermore CPM 3V is also high in vanadium and carbon which causes the formation of vanadium hard carbides, which enhances its wear resistance abilities.

If you’re in search of an instrument that can serve your family for generations to come, regardless of the different applications, take a look at the options for CPM 3-volt knives.

CPM 3V Steel Edge retention

The hardness of the steel affects the edge retention capacity of steel; the harder it is the greater edge retention capacities.

This steel is a high-quality one that has the highest hardness and edge retention capabilities, these attributes are admirable. It is sharper longer than other steels for tools available, however it’s not as durable as the premium steels.

CPM 3V steel corrosion Resistance

So , is CPM 3V’s steel stainless? CPM 3V isn’t stainless steel, however the chromium elements that make up its composition gives it excellent anti-corrosion properties. Because this steel isn’t designed to resist corrosion the proper maintenance is required to ensure that it is not becoming rusty. Careful cleaning involves drying it following use.

To increase the resistance to corrosion manufacturers use strong anti-corrosion coatings. CPM 3V’s corrosion resistance is on par with CPM Steel CruWear.

Ease of Sharpening CPM 3V Steel

Since it is a hard metal Sharpening CPM 3V steel can take the time as well as effort. To help ease the process the users are advised to choose abrasives that are more powerful.

Sharpening your edge using this kind of steel can be an overwhelming task when you don’t have the proper sharpening abilities and tools.

The good thing is that blades made of this type of steel can hold an edge for a lengthy. So, you won’t be forced to go through the hassle of sharpening your blades each time.

CPM 3V Steel Comparison

CPM 3V steel against S35VN

Both 3v and S35VN steel have nearly the same edge retention. But S35VN steel is superior in terms of edge retention, resistance to corrosion and is also more easy for sharpening than 3V. However, 3V shines in toughness. If it comes to cost, CPM 3V is cheaper than S35VN.

CPM 3V vs CPM 10V Steel

Both 3V and 10V steel are part to the family of crucibles that comprise the high-vanadium steel. CPM 10V is stronger than 3V. It provides outstanding edge retention and wear resistance over 3V. The most distinctive feature in 10V over 3V is it’s remarkable strength even when it is at the highest level of hardness, which is around 64HRC.

CPM 3V steel vs CPM M4

3V steel and M4 steel are manufactured using CPM technology, however they different properties. 3V steel has the highest strength as well as corrosion resistance. Additionally, it is more easy to sharpen, whereas M4 steel has more edge retention.

CPM 3V steel vs D2 Steel

3V steel and D2 steel are both tool steels and have identical performance. CPM 3V could be considered to be the superior of the two due to its greater toughness, superior edge retention, and is comparable to D2 Steel for corrosion resistance.

CPM 3V steel vs S30V

CPM 3V steel is superior in Edge retention and durability over S30V steel. In addition, S30V is superior to CPM 3V steel when it comes to the resistance to corrosion since it’s stainless steel. Both are comparable in terms of the ease of sharpening.

Are CPM 3V the best knife steel?

CPM 3V has all of the characteristics that make for a great knife steel, which includes outstanding toughness, excellent edge retention and wear resistance.

Its main disadvantage is the lack of resistance to corrosion, which can be easily addressed with an the anticorrosive coating and the proper maintenance.
