The dream of every knife shopper is to get a blade that aligns with his or her cutting needs perfectly. But every steel type excels well in situations that meet its strengths. For instance, high corrosion resistant steel does well in wet and high humid areas, while tough steel handles high impact jobs excellently.
But when you need an excellent performer for all situations and weather, all-around premium stainless steel like CTS XHP is the way to go. And as the name says, CTS XHP is a product of the US-based Carpenter Technology. It’s a powder metallurgy creation high in carbon and chromium for excellent performance.
Some experts describe its performance as equivalent to a highly corrosion-resistant D2 or a higher hardness 440C. But for us, we say you go through the CTS XHP steel review below and decide if it’s the steel you’ve been yearning to own.
At A Glance
One thing every knife user will tell you is that premium steels never disappoint. Yes, they are pricey but worth every dollar. To better illustrate, imagine steel as hard as D2 but with the corrosion resistance of 440C. And that is CTS XHP premium stainless steel for you.
It’s scarce steel commonly used in high-end knives, surgery tools, and comparatively expensive cutlery. You better order a CTS XHP steel blade online as finding any in your local store may be highly chancy. But meanwhile, find out what to expect from this steel in this CTS XHP steel review article. Also, we will recommend some great CTS XHP steel knives worth adding to your collection.
- Great wear resistance
- Terrific edge retention
- High corrosion resistance
- Reasonably challenging for its hardness
- Relatively easy to work with
- Moderately difficult to sharpen
CTS XHP Steel Chemical Composition
Below are the elements that form the CTS XHP stainless steel alloy.
- Carbon, 1.60%: It increases the hardness and consequently the wear resistance. The high hardness also results in excellent edge retention.
- Chromium, 16%: Makes CTS XHP highly corrosion-resistant stainless steel (surpasses the minimum 12% chromium) and boosts the hardenability, tensile strength, and toughness.
- Molybdenum, 0.80%: Boosts the CTS XHP strength in high temperatures, hardens it further, and results in better corrosion resistance.
- Manganese, 0.5%: It increases the machinability of CTS XHP and the hardenability and tensile strength.
- Silicon, 0.40%: Apart from ridding molten steel of oxygen bubbles, it also boosts strength and hardness. However, silicon needs to be in tiny quantities to keep its brittleness effect on steel in check.
- Nickel, 0.35%: Enhances toughness, hardenability, and corrosion resistance of steel.
- Vanadium, 0.45%: Increases the strength, toughness, and wear resistance of CTS XHP steel. It also boosts corrosion resistance.
CTS XHP Hardness
CTS XHP steel has a hardness range of 60 to 64 HRC. The range is way higher than your usual everyday carry knife (57-59HRC), but many manufacturers keep their blades at 60 HRC. Even so, knife makers can achieve any hardness level depending on their heat treatment.
The main reason for the high hardness is the massive carbon amounts in the alloy. The following are the recommended heat treatment temperatures:
- Annealing: 1550-16000F
- Stress relieving: 12000F
- Austenitizing (high heat): 1850-20000F
- Quench: Quench in a salt bath to 1000-11000F, and then air cool to 1500F.
- Tempering: The recommendation for best results is tempering twice or thrice at a minimum temperature of 4000F and air-cooling to room temperatures between tempers. Watch the temperatures closely as tempering at temperatures above 8000F lowers the corrosion resistance of CTS XHP steel.
CTS XHP Physical Properties
Expect CTS XHP steel to have the following characteristics:
1. Great Wear Resistance
Hard steels are excellent in wear resistance. CTS XHP steel won’t wear down quickly even while under constant use in challenging cutting tasks. It ensures the abrasion of regular re-sharpening cycles outstandingly.
2. Terrific Edge Retention
If you have dealt with hard steels before, then you know that CTS XHP has what it takes to hold an edge for months. Simply put, this steel has excellent edge retention that lasts long, even under heavy usage. CTS XHP holds an edge better than the famous S30V steel.
3. High Corrosion Resistance
High corrosion resistance is another strength of CTS XHP steel. As earlier stated, its corrosion resistance is as high as that of 440C. Expect a CTS XHP steel blade to perform excellently in all weathers and wet environments.
4. Relatively Tough
Hardness and toughness in steel are inversely related. That means hard steels are less tough and chip easily under impact. But surprisingly, CTS XHP steel is way tougher than you would expect in steel that hard. Of course not tough enough for use in axes and longer blades, but it holds well to impact tasks while used in shorter blades.
5. Good Machinability
CTS XHP is not the most straightforward steel to machine but is way better than most hard steels. Its good machinability makes the knife-making process easier and less costly, translating to some cost-saving to the buyer.
6. Moderately Difficult To Sharpen
Hard steels are hardly sharpenable. CTS XHP steel is moderately difficult to sharpen compared to extremely hard steels. Standard sharpening tools such as a whetstone will barely give CTS XHP any edge. For some considerable results, go for at least a diamond stone and some lubricating oil or other modern advanced sharpening systems. Sharpening a CTS XHP steel knife is beginner unfriendly, and you better seek professional help if you’re a total novice.
CTS XHP vs. Steels
So, how does CTS XHP steel compare with other steel types? Let’s find out below.
CTS XHP vs. Maxamet
Both Maxamet and CTS XHP steels belong to the class of high-end steels. However, CTS XHP overall performance is better than that of Maxamet. CTS XHP steel can’t hold an edge as long as maxamet but has better corrosion resistance.
CTS XHP vs. M390
These two steels are both in the premium category, but M390 is in the top-tier ultra-premier league. It offers better corrosion resistance and edge retention. It’s also pricier and more difficult to sharpen than CTS XHP steel.
CTS-XHP vs. S30V
CTS XHP and S30V are both premium steels and among the hardest steels popular in the knife industry. These two steels won’t give you an easy sharpening time but will hold an edge impressively. However, CTS XHP retains an edge for longer but is more difficult to sharpen. While both steels are great in corrosion resistance, S30V is better. Also, S30V is more common and more popular.
Is CTS XHP Steel Good for Knives
CTS XHP steel is not only good but also excellent for knives. CTS XHP steel is an all-around performer, with excellent edge retention, excellent corrosion resistance, and high durability. Its toughness is reasonable for its hardness, and the sharpening is not that difficult.
Even so, you will spend longer sharpening this steel than you would softer steels, but the effort is worth it. This steel is pricey but will undoubtedly serve you for a lifetime. Unfortunately, CTS XHP steel is not that common, and only a few big brands can barely get enough for their knife needs.
