CTS-XHP is American steel that has all-around performance. As a knife fanatic, your search for a steel blade that has high performance ends here with this steel that possesses corrosion resistance, retains the edge well, and has high toughness. So, we thought to review CTS-XHP steel, the premium steel used in various high-end knives.
But, before you pick the CTS-XHP knife, you should know about the composition of the steel, its history, and its features. How well it performs in retaining the edge? Does it prevent corrosion and rust build-up? How much does it prevent chipping? Is it easy to sharpen?
We’ll in this article delve deep into these questions in different sections to bring you the information about steel. We’ll review different knives and compare them with other steels in this article.
What Is CTS-XHP Steel?
The CTS-XHP steel is powder metallurgy stainless steel. Carpenter’s company manufactures it. CTS-XRP is an alloy that is a combination of different elements and metals. It is air-hardening, high Chromium, high carbon, and corrosion-resistant alloy.
The steel possesses high corrosion resistance and has high hardness, more than other steel in the market. Moreover, CTS-XHP balances hardness and toughness in an ideal way, making it one of the top choices for knife manufacturers.
CTS-XHP steel Composition

The steel composition is the essence of the steel. Therefore, the combination of metals and elements reflects the feature of steel.
Carbon (1.60%) helps harden the steel, increases tensile strength, and improves wear resistance.
Chromium (16.00%) qualifies the steel for corrosion resistance. In addition, it boosts tensile strength, toughness, and hardness.
Manganese (0.50%) makes the steel hard and enhances tensile strength. In addition, it prepares the alloy for machinability.
Molybdenum (0.80%) increases the strength, hardenability, and toughness of the steel.
Vanadium (0.45%), the low level of vanadium, strengthens the steel’s wear resistance. It also enhances corrosion resistance.
Nickel (0.35%) increases corrosion resistance and improves the toughness of steel.
Silicon (0.40%) boosts toughness and hardness. However, too much Silicon can make the steel brittle and decrease the wear resistance.
CTS-XHP Steel Properties
Toughness
The CTS-XHP steel has good toughness. As per the thumb rule of steel manufacturing, steel should not be too challenging. Otherwise, it will be prone to chipping. The toughness of CTS-XHP is high. It has 64HRC, which means it is made for heavy-duty work.
Wear Resistance
It has superb wear resistance. The steel’s hardness is akin to D2 steel. The XHP has a similar composition to D2 steel which means it has excellent hardness. The steel will withstand day-to-day wear and tear without deformation of the actual shape. The steel composition has a high carbon and chromium content, which will keep abrasion at bay, even after frequent re-shaping.
Sharpness
It has a high hardness score on Rockwell Scale, which depicts it is difficult to sharpen the knife. But other steels are harder than this, and that can be sharpened with the right tools. Therefore, the difficulty level of sharpening the blade of the CTS-XHP steel knife is moderate. Moreover, due to its high toughness and wear resistance, the knife goes a long way without the need for sharpening.
Corrosion Resistance
The steel offers excellent corrosion resistance. As a fact, above 12% of Chromium qualifies the steel to be rust-free and corrosion-resistant. In addition, CTS-XHP steel has 16% chromium content, which prepares the steel as stainless, keeping the rust at bay.
Edge Retention
Due to the incredible high hardness of the steel, the blades have excellent edge retention. As a result, you can use the CTS-XHP steel knife for chopping, mincing, slicing, and dicing vegetables and meat and would not see the edge getting dull.
CTS-XHP Steel Heat Treatment
The annealing of CTS-XHP steel is done in a neutral atmosphere. First, it is heated uniformly at 1550-1600 degrees Fahrenheit. After that, the steel is cooled down at 20 degrees Fahrenheit. Next, heat it at a slow pace in the furnace for an hour. It is kept on the stove until the furnace becomes black. Then it is removed and allowed to cool at room temperature naturally.
CTS-XHP Steel Hardness
CTS-XHP registers high hardness on Rockwell Scale. The hardness of the steel range from 60-64 HRC. It is due to the hardness of D2 steel. The range of hardness is typically higher than the average. It is due to the high carbon content in the mix of different metals and elements. This enhances the wear resistance of the steel along with the edge retention. Keep in mind the hardness can vary from 60HRC to 64 HRC for manufacturing knives.
Is CTS-XHP Steel Good For Knives?
CTS-XHP steel is an excellent choice for manufacturing knives. It has well blend of features like edge retention, excellent corrosion resistance, and resistant to chipping of steel. Furthermore, the steel does not deform due to the sharpening of the edge, and it has good toughness.
You need a knife that is easy to sharpen for knives, but CTS-XHP is not easy to sharpen. However, it won’t cause you much trouble as the blades will hardly need sharpening, and if sharpened with the right tools, it will offer you a razor-sharp edge. So, with this information, we can conclude that CTS-XHP is an ideal choice for knives.
Is CTS-XHP Steel Stainless?
Yes, CTS-XHP steel is stainless due to D2 steel and high Chromium and Vanadium content.
