Details CPM CruWear Steel Review

Crucible Industries produces CPM CruWear steel, an air-hardening steel for use in tool making. It is ideal for use in assembly tools due to its excellent wear resistance and toughness.

CPM CruWear Steel is a knife steel that provides balanced performance in edge retention and corrosion resistance. It is one of the few steels that does not have a bias in any of these properties.

CPM CruWear steel knife is a high-performance product in terms of wear resistance and toughness. It also has high Rockwell hardness. This is a modified version of D2 Steel with a higher percentage of Vanadium Carbides, which are superior to the more chromium-rich D2 steel.

It is important to note that CruWear steel and CPM CruWear are not identical . CPM CruWear is the most similar to Z-Wear. CPM-CruWear, an upgraded version to conventional CruWear, has improved toughness.

This steel is used primarily in the manufacture of shearing blades and handheld wood planes. It is a favorite among knifemakers due to its toughness, wear resistance, edge retention and toughness.

CPM CruWear Steel Composition

  • Carbon 1.10%: Enhances edge retention, hardness, and tensile strengths. It increases steel resistance to wear and abrasion as well as corrosion.
  • Chrome Cr 7.50%: Chromium Adds hardness, tensile and corrosion resistance to a blade.
  • Molybdenum Mo 1.6%: Increases machinability, corrosion resistance.
  • Vanadium V 2.40 %: Combines vanadium carbide with other elements to improve wear resistance.
  • Tungsten W 1.15 %: Mainly added to increase hardness in high-temperature applications.

Properties CPM CruWear Steel

CPM CruWear Steel Hardness

CPM CruWear Steel’s Rockwell Hardness is 64HRC. Depending on the heat treatment, the Rockwell Hardness may vary from 60 to 65 HRC. CPM Cru-Wear steel is available for knifemakers. It can be hardened with Salt, Vacuum or atmosphere.

CPM Cru Wear steel is unique in comparison to D2 because it has adequate Tungsten, Molybdenum. This secondary hardening response results in a higher Rockwell hardness up to 65 HRC.

This steel alloy also has more precisely tuned components to ensure a higher level of hardness and wear resistance. CPM-CruWear knives will provide excellent wear resistance because of their higher Rockwell hardness.

CruWear Steel Toughness

CPM CruWear is a steel with great toughness. It measures up to the industry standard for toughness. This means that a blade made of this steel will not break or chip easily, even under tough planning. It is much tougher than 3V knife steel and significantly more durable than D2 steel.

This steel’s high toughness can be attributed to the crucible metallurgy process that produces it. It ensures an even distribution of the smaller carbides. You can increase the toughness by decreasing the hardness, which will result in less brittleness.

CruWear Steel Wear Resistance

CPM CruWear steel is just like any other tool steel. It has a high wear resistance. High hardness is responsible for the steel’s excellent wear resistance. Its perfect combination of Vanadium and Carbon in its alloy helps to form vanadium carbides which are more wear-resistant.

CPM CruWear steel knives are durable and will last generations, even with regular use and sharpening.

CPM CruWear Steel Edge retention

CPM-CruWear steel blade steel is also very hardy, so you will be happy with its edge retention.

CPM CruWear’s edge retention is not the best on the market, but it is sufficient for daily cutting. CPM Cru-Wear’s edge retention is comparable to that of CPM4V and S35VN knives steel.

CPM Cru-Wear knives are a great choice if you want a knife that can be used outdoors and does not require any resharpening.

CPM CruWear steel Corrosion Resistance

CPM CruWear, while not stainless steel is good at resisting corrosion because it has low levels of Chromium. It is not the most resistant to corrosion, but it is better than some other options.

It has a higher corrosion resistance than nonstainless knives steels like HAP 40 and CPM Prox 45. It’s comparable to Z-Tuff and CPM 3V. CPM CruWear steel knives cannot be used in salty, humid, or wet environments.

You can prevent your knives from rusting or corroding by using good cleaning and maintenance techniques. After each use, wash and dry the blades.

Sharpening CruWear Steel

It is important to think about how difficult it will be for you to sharpen this steel with high toughness, hardness, and wear resistance.

CPM CruWear steel is very easy to sharpen so you don’t have to worry about keeping an edge.

CPM CruWear knives can be sharpened easily with simple tools such as low-grade abrasive material.

A sharpening stone can be all you need to maintain a functional edge if you’re out in the wild and don’t have access to sharpening tools.

CruWear Steel comparison

Cru-Wear and S30V Steel

S30V Steelis a premium Stainless Steel with a higher Chromium Content, making it more resistant than CPM Cru-Wear steel.

CPM S30Vsteel has a Rockwell hardness of 58-61 HRC. However, it offers greater wear resistance and edge retention that CPM CruWear. This is due to the higher levels of Vanadium Carbides. CPM CruWear contains 2.4%, while S30V has 4%.

CPM Cru Wear steel is more durable than CPM S30V and is easier to sharpen. Your application will determine which knife steel you choose. You will find a knife that is more resistant to rust and has better edge retention, but it is slightly more expensive than a CPM CruWear knife.

CruWear vs 3V steel

CPM 3V and CPM CruWear are both produced by Crucible industries, which uses the CPM process. CPM CruWear has more carbon than 3V Steel making it harder, more durable, and better at edge retention and wear retention.

Both steels share a common characteristic: they have low levels of Chromium, which makes them less resistant to corrosion. Both steels offer similar toughness, but CPM3V is slightly more durable.

CPM CruWear steel vs D2 steel

CPM CruWear steel and D2 are both tool steels. CPM CruWear steel can be described as an upgrade of D2 tool-steel with sufficient amounts of tungsten or Molybdenum, giving it a higher Rockwell hardness level and better wear resistance.

CPM CruWear steel has a higher alloy content than D2 steel because it has less carbon and chromium that can form brittle chrome carbides.

CPM Cru-Wear knives will be more durable than D2 knives in terms of toughness. CPM Cru Wear steel is twice as tough as D2 steel.

Both are similar in their edge retention, so they will both be easy to sharpen. CPM CruWear is more resistant to corrosion than D2 steel. CPM-CruWear knives will rust faster than D2 steel.

CruWear vs. M390

Bohler M390 stainless steel is more than CPM CruWear. Both steels have a hardness of 64 HRC. However, M390 steel has a higher wear resistance and contains more Vanadium Carbides. Micro-clean M390 knife steel has high wear resistance and is stainless steel.

Bohler M390 stainless steel is more durable than the non-stainless CPM CruWear stainless steel. The 20% chromium content of M390 alloy is one of the highest among knife steels.

It is comparable to CPM 20CV, CTS 204P and MagnaCut steel in terms of corrosion and rust resistance.

CPM Cru Wear steel is tougher than M390 steel but it’s easier to sharpen and more affordable.

CPM CruWear vs Elmax

CPM CruWear steel is not stainless steel, while Elmax steel is stainless steel with higher chromium than CPM CruWear. Elmax steel knives will provide suitable performance in corrosive environment. A CPM CruWear steel knife can rust easily if it is used daily. An Elmax knife knife will not rust.

CPM CruWear steel and Elmax have identical edge retention levels, but there is a difference in their toughness. CPM CruWear steel offers almost twice the toughness of Elmax steel. CPM CruWear steel knives are less susceptible to cracking and chipping than Elmax steel knives.

CruWear vs Maxamet

CPM CruWear steel and Maxamet have different hardness levels. Maxamet steel has a Rockwell hardness up to 70 HRC, while CPM CruWear steel offers a similar level of hardness at 65HRC.

Maxamet’s hardness is remarkable for edge retention. Maxamet is the best knife steel for edge retention, apart from Rex121.

Maxamet is less durable than CPM-CruWear due to its high hardness. CPM CruWear steel can have a toughness four times greater than Maxamet.

CPM CruWear knives will be easier to sharpen than Maxamet knives, which are extremely wear resistant. It will also offer greater corrosion resistance.

Is CPM CruWear Steel good for knives?

CPM-CruWear is a great steel for knives because of its hardness, excellent wear retention and ease in sharpening.

CPM CruWear’s blade steel has a limited corrosion resistance. However, you can still protect your knives by drying them and cleaning them afterwards.
