Details CTS BD1N Steel Review

What’s CTS BD1N steel?

CTS BD1N steel, which is nitrogen-based and high-carbon chromemium, is vacuum-melted stainless steel. It was produced by Carpenter, an American firm. The steel is extremely hard due to the combination of carbon and chromium.

CTSBD1N does not contain the same steel as CTSBD1 steel. CTSBD1N, which is nitrogen-based stainless metal, is denoted with the N at its end.

This steel is loved by Knifemakers for its quality, composition, and machinability. Its corrosion resistance is increased by the inclusion of chromium, while Nitrogen reduces the risk of cracking and chipping.

Its superior hardness makes it an excellent choice for knife makers as well as users.

The knife industry uses CTS BD1N to make general knives, such as pocket knives and camping knives. It is also used in other industries to make small parts and ball bearings.

CTS BD1N Steel Composition (CTS-BD1N Steel Chart)

  • Carbon 0.95%: Enhances edge retention, hardness and tensile strengths. It increases steel resistance to wear and abrasion as well as corrosion.
  • Chrome Cr 17..00%: Formations of Chromium carbides. This increases the blade’s hardness and tensile strength as well as corrosion resistance.
  • Nitrogen N 0.15 : Increases the steel’s hardness and also improves the grain structure to avoid cracking or chipping.
  • Molybdenum Mo 0.5%: This improves machinability.
  • Phosphorous P 0.033%: Enhances steel’s strength and improves its machinability
  • Manganese 1.00%: Increases steel’s strength and hardness. The steel’s hardenability can be improved by heating it.
  • Silicon Si 1.0%: Increases strength, heat resistance.
  • Sulfur S 0.03% : Enhances machinability, but is considered an impurity when used in large quantities.

CTS BD1N steel properties

CTS BD1N Steel Hardness

CTS BD1N’s Rockwell hardness is 60-63 HRC. High levels of carbon and chromium make it hard. It also has a super-fine grain structure due to the presence of Nitrogen.

Steel Toughness

CTS BD1N steel has decent toughness. This is due to the low-level Nitrogen elements that make up its composition. It has a fine grain structure.

This steel is very hardy and can withstand a lot of abuse.

CTS BD1N’s toughness isn’t the greatest, but it is still decent. Other steels such as Elmax steel, CPM 154 steel and S35VN will give you better edge retention and toughness.

CTS Steel Edge retention

CTSBD1N steel excels at edge retention. This is due to its high hardness.

CTS BD1N stainless Steel has a good edge retention, but it is better than AUS 8, 8Cr13MoV, and 14C28N steel.

If you’re looking for a knife that won’t require sharpening every time, then you should look at the CTS BD1N range of knives.

CTS Steel Corrosion Resistance

CTS BD1N stainless steel contains high levels of Chromium, Nitrogen and is made from stainless steel. It would be reasonable to expect that the nitrogen in the composition would affect its resistance to corrosion, but it actually improves it.

CTS BD1N is resistant to rust and staining. Knives made of this steel need to be protected from rusting. They cannot be left in a corrosive environment without protection and expect them to not rust.

After use, wipe the blades dry with a damp cloth. This is called maintenance. To keep stains away, you can also apply oil to the blades for storage.

CTS Steel Wear resistance

CTS BD1N steel blades last a long time. This is due to the excellent edge retention properties and chemical composition.

This steel is strong and can withstand everyday use without deteriorating faster. CTS BD1N knives are therefore expensive.

Easy Sharpening CTS BD1N

Because of its hardness, you would expect this BD1N stainless steel to be difficult to sharpen. It is easy to sharpen. It has a fine grain edge thanks to its fine-grained Nitrogen elements.

This steel is a favorite among knife users because it holds a sharp edge for a long time and is easy to use. Even with the simplest of sharpening tools, it will take less time and effort to get a razor-sharp edge.

CTS-BD1N Steel Comparison


CTS BD1N is different from CTS BD1N because of the N at CTS BD1N. BD1N stainless steel is nitrogen-rich and better than CTS BD1N because it falls under the high-end category. BD1N steel has a higher hardness, which makes it more resistant to wear and edge retention.

CTS-BD1N steel has a significantly higher corrosion resistance than regular CTS-BD1 steel. BD1N is generally a better steel because it is an upgraded version of CTS BD1 Steel.

CTS BD1N also isn’t very common making it more costly. CTS BD1N knives are less common, so they are more expensive.

CTS-BD1N vs S30V

There are significant differences in the chemical compositions of BD1N and S30V steels. CPM S30V is a more complicated steel that has refined alloy and metallurgy production processes which produce finer grain structure.

CTS BD1N is more tough than S30V steel for edge retention and toughness. BD1N, a nitrogen-based alloy, is slightly harder and more resistant to corrosion and wear than S30V steel.

CTS-BD1N vs. VG10 Stahl

CTS BD1N steel has a higher corrosion resistance than VG-10 Steel due to the inclusion of Nitrogen elements within its alloy composition. BD1N steel is more resistant than VG10 Steel and less prone to cracking and chipping.

The alloy of VG-10 Steel gives it an excessive hardness due to the high chromium and Vanadium content, but also causes cracking and chipping.

CTS BD1N nitrogen-based steel has a superior edge retention rate than VG-10 stainless. Although they are almost identical in price, CTS BD1N stainless is a better steel.

You can also see the S45VN steel review for a new, nitrogen-based steel. I’ve explained in detail why S45VN is slightly better than CTS-BD1N steel.


CTS BD1N and D2 steel are different in that CTS BD1N is stainless steel while D2 is not enriched with enough chromium elements to make it stainless.

D2 steel, which is tool steel, has a higher Rockwell toughness than CTS-BD1N. This directly translates into better edge retention and wear resistance. It also beats CTS-BD1N steel for wear resistance and edge retention.

The same toughness will be offered by both CTS BD1N and D2 knife steel. They are below-average in toughness and not recommended for knives with long blades or knives that will face extreme toughness.

The Powder metallurgy-produced MagnaCut steel is a better steel than CTS BD1N stainless and D2. It offers superior edge retention, toughness and resistance to corrosion. It is twice as tough as CTS BD1N knife-steel, has the same edge retention and corrosion resistance as D2 steel, but it has twice the strength.


CTS BD1N is more expensive than M390, but M390 is superior to CTS BD1N. The main difference between CTS BD1N and M390 is their edge retention. Bohler M390 premium steel has twice the edge retention as CTS BD1N.

Wear resistance is another notable distinction between M390 stainless steel and BD1N. M390 steel is extremely wear-resistant because it has been designed to provide exceptional wear resistance and still retain stainless steel properties.

Both steels have below-average toughness and are not suited for demanding or difficult applications. Both steels are resistant to corrosion, however M390 knife steel has a slightly higher chromium level than BD1N knife.

CTS-BD1N can be sharpened more easily than M390, but M390 steel has a much better edge retention so you won’t have to sharpen it nearly as often.

Is CTS BD1N good knife steel?

Yes! Yes! This steel is very sharpenable and has excellent edge retention. It also offers great wear resistance, good toughness, high corrosion resistance, and decent edge retention. This steel has one drawback: it is more expensive, so its knives can be more expensive.

How strong is CTS-BD1N Steel?

CTS BD1N steel has superior corrosion resistance than other knife steels on the market. Magnacut, LC200N and M390 are all steels that can match the BD1N’s corrosion resistance.

Although CTS-BD1N stainless Steel edge retention and toughness are not very good, it beats many steels used for knife making. While you will have better edge retention and toughness than other steels, it is less resistant to corrosion.
