Apr 21, 2022 · But I agree with Wartstein's comments. If you already have a PM2 in S30V, you will find scarcely a difference with S45VN, and if I was you, I would go with the Cruwear for just that reason. Get something a bit different and expand your experience. I really enjoy the knives I have in Cruwear.

July 5, 2023. S30V is significant to the knife world. It spurred the widespread use of CPM (Crucible Particle Metallurgy) steels in bladesmithing. These powdered steels were …When it comes to corrosion resistance, 20CV and S45VN are stainless steel with very good corrosion resistance. However, CPM 20CV stainless steel exhibits better corrosion resistance than S45VN stainless steel for knife applications. S45VN has 16% chromium and 2% molybdenum in its composition, In comparison, 20CV is comprised of 20% chromium and ...indicate that CPM S45VN, CPM S35VN and CPM S30V are much more resistant to chipping and breaking in applications which may encounter side loading. In knifemaking, the higher transverse toughness makes CPM especially good for Edge Retention (CATRA Testing Relative to 440C) Grade % CPM S45VN 143* CPM S35VN 140* 145 154CM 120 440C 100The main difference between S30V and S35VN steel is their toughness. S35VN steel is considered to be tougher and is, therefore, better suited for larger knives such as hunting, tactical, and survival knives. S30V steel, on the other hand, is more suitable for smaller pocket knives that will be subjected to less heavy use.154CM vs CPM S35VN – Complete Comparison Hardness. Hardness significantly impacts a knife steel’s edge retention and wear resistance. 154CM exhibits a Rockwell hardness (HRC) of 58-61, which strikes a fine balance between toughness and edge retention. This steel can endure considerable use without chipping or breaking.When comparing S45VN to other steels like S30V, it’s important to note the slight increase in Carbon, Chromium, and Niobium in its composition.InvestorPlace - Stock Market News, Stock Advice & Trading Tips Source: g0d4ather / Shutterstock.com It’s a new week and that means it...

Overall, S45VN is a great choice for knife makers looking for a high-end steel that offers excellent edge retention, toughness, and corrosion resistance. It is comparable to CPM S35VN and CPM S30V in terms of edge retention, toughness, and machinability, but it has the added benefit of being more corrosion resistant.Cutting performance will depend on which ever one is ground more optimally. For most materials S30V will significantly outlast AUS-8, as it is harder and more wear resistant. The only real concern is that there have been some reports of poor intitial problems with S30V which required some extensive sharpening to correct poor steel in …S30V - $33.65/ft. (+50%) S35VN - $33.81/ft. (+51%) The most interesting results from these cost comparisons are that the highly popular D2 steel is only slightly more expensive than 440C and there is no significant cost difference between S30V and S35VN.S35VN is usually closer to ELMAX or CPM-154, where VG-10 is usually closer to 154CM. Like ELMAX, it does a great job holding an edge, but it performs really well across the board. It is a tough steel and has excellent corrosion resistance. An like ELMAX, it's still a very tough steel at even 60. I think it is easier to sharpen than S30V.S45VN has a higher content of chromium carbide compared with S35VN and S30V, with equivalent MC to S35VN but lower than S30V. So we expect better edge retention than S35VN but where it sits compared to S30V is hard to predict with certainty.CTS BD1N vs S30V. The chemical composition of BD1N steel and S30V steel is very different. CPM S30V steel is a more complex steel with refined alloy and powder metallurgy production processes that produces finer grain structure. ... I have reviewed in detail why S45VN steel is slightly better than CTS BD1N steel.Para 3 Sprint s45n or CS CTS-XHP. As title, for blade steel mainly, the sprint s45vn or the cutlery shoppe exclusive CTS-XHP 😎. I still am not convinced that s30v/s35vn/s45vn are all that special. They arent bad and they are all arounders but they also dont have any qualities that make them seem impressive in anyway.Here is the short answer: CPM-S45VN has a slightly higher amount of chromium and niobium than S30V, which can improve its wear resistance and toughness. Both steels are great choices for high-end knives, but CPM-S45VN may be a better choice for applications that require extreme wear resistance and toughness.

Here are 10 of our favorite fixed blade and folding Buck knives with SV30, SV35 or S45V steel: 103 Skinner Pro. 656 Pursuit Pro. 119 Special Pro. 102 Woodsman Pro. 110 Hunter Sport. 250 Saunter. 040 Onset. 841 Sprint Pro.Oct 7, 2023 · The stainless properties of s90v and s30v are roughly the same, but the s90v holds a working edge noticeably longer. I prefer s45vn to s30v, but only because s45vn is significantly more stainless than s30v. Edge retention between s30v and s45vn seems similar, but I've had s30v rust in my pocket while s45vn has proven to be m390-level stainless. S45VN is newer. I do not have any, but definitely want some. - S45VN has a finer grain structure and 1% less Vanadium than 20CV. It will probably touch up easier and depending on hardness, may have better edge stability. - 20CV is more corrosion resistant. 4% more chromium. But probably not too noticable.If you use your knife hard, get Cruwear. If you want to care for it less, get S45. So in a nutshell : - CruWear : tougher, better edge retention, but less rust resistant. Sharpening +++. - S45VN : less maintenance regarding to rust, but less tough and hard. Sharpening ++.The chemical composition of S30V and 20CV are two of the most widely used high-performance knife steels. Both are highly sought after for their strength, durability, and corrosion resistance. S30V steel contains mainly Carbon, Chromium, Molybdenum, and Vanadium, while 20CV steel contains Carbon, Chromium, Molybdenum, and Vanadium …Jan 31, 2022 · It’s more corrosion-resistant than S30V is, and it performs quite well compared to Elmax, S35VN, and even M390. The lead picture is a knife with S45VN, and it has functioned as promised.

SPY27 vs S45VN Both SPY27 and S45VN can be considered improvements to the already successful Crucible S30V and S35VN steel. SPY27 performance falls somewhere in between S30V and S35VN steel, S45VN, on the other hand, is an improvement of S35VN and thus beats Spy27 in performance in all aspects including …New Steel – Crucible S45VN. by Larrin » Fri Nov 01, 2019 3:04 pm. Crucible and Niagara have just announced a new stainless powder metallurgy steel – S45VN. I was able to get a bar of it early to do a range of experiments on it including hardness, corrosion resistance, and toughness. I have a recommendation on how to best heat treat it too. In-Depth Comparison. Edge Retention: CPM-S90V offers far superior edge retention compared to S45VN. So if you are going to need a knife you will touch up once and last a long time, S90V is the better steel. Corrosion Resistance: Generally, S90V will offer slightly better, if not, the same corrosion resistance as S45VN. Then on the S35VN sheet they give Charpy data and it show's S35VN as having scored 2 ft-lbs higher than S30V. @nsm Website show's CPM-154CM as having substantially more toughness on their graph than CPM-S35VN. So I'm confused, some sources say CPM-S35VN is tougher, some equal, and some not as tough as CPM-154.- Blade Chasers. Magnacut Vs S45vn: Evaluating The Performance Of Premium Knife Steels? Robert M. Clayton. August 4, 2023. Comparison. Knife making …Jul 1, 2021 · S30V is generally considered to be better than 440C steel choice due to its superior edge retention and corrosion resistance. It is a high-performance alloy that is specifically designed for use in knives . S30V vs S35VN. The main difference is that the S35VN steel blade contains a finer grade, it is easier to machine and polish than S30V.

4V should be in the neighborhood as well, with a more wear/less toughness than CPM Cruwear balance. Imagine S30V wear with almost 3 times the shock and toughness ( 3V and PD#1 can get almost up to 3-4 times the shock toughness). All slightly different flavors with different attribute balances. I'll be honest. The specific formula for S35VN knife steel - aka the "ultimate mainstream steel" - is 3% vanadium, 1.4% carbon, 0.5% niobium, 2% molybdenum, and 10.5% chromium. This composition makes it tougher (resistance to edge chipping) without reducing the wear resistance (edge holding) of the steel. S35VN also has a finer grain structure than S30V. Since both the s35vn and s30v are made using the same process, they have similar properties. However, at the same time, both of these steels have their fair share of differences as well.
