CPM 154 is on par with S30V, as it is the powder steel version of 154CM, but anyone who says 154CM is 'better' than S30V is doing so because of sentimental value of 154CM on a certain knife, rather than an objective perspective. 154CM has more or less the same toughness as S30V, but less ...But this steel, which is a sequel to S35VN and a grandchild of S30V, is out in force. Spyderco updated many evergreen models to run S45VN as a base steel, and the results are great. It’s more ...CPM MagnaCut is produced by Crucible and hot rolled and distributed by Niagara Specialty Metals. This is the same production and distribution path used by other CPM steels like S45VN, S30V, S35VN, 20CV, S90V, etc. So the steel will eventually have full availability through steel suppliers and to knife companies.The difference in properties in these steels is so small that even materials tests have difficulty in telling them apart. For example here is the abrasive wear resistance (pin on disk) : S90V : 2150/975 F : 61.5 HRC : 37 mg. S110V : 2150/975 F : 62.5 HRC : 34 mg. The wear resistance is measured by material loss in mg.The two steels differ in their carbon content. D2 has 1.5% carbon, while S30V has 1.45% carbon. S30V is slightly more durable than D2 but less prone to cracking or chipping when used in the field. As i explained above S30v is more corrosion-resistant than D2 Steel because it contains more chromium.0.03%. CPM S90V Knife Steel has remarkable wear-resistance and corrosion-resistance qualities! One aspect of knives using Crucible CPM S90V is the cost. This alloy is very hard on grinding belts and the machines that use them, transferring that cost to the end product. That being said, the almost cult-like following of those collectors …S90V and M390 are premium steels, but M390 makes better high-end knives because it wins in toughness, corrosion resistance, and ease of sharpening. However, you must consider your knife needs when choosing between S90V and M390 knives. In this article, we will look at the properties of S90V steel and M390 steel and their pros …Taking a look at Spyderco's prices, you're probably going to be looking at an added $20 from S30V to S90V and another $20 from S90V to S110V, but that's just a rough guess. The other issue is that knife companies tend to bling out the knives with better steels. Take Steel Will. They do D2 and M390 versions of the same knives.LC200N and BD1N have much lower wear resistance than S30V and the CATRA test is an edge wear test. Any test showing comparable performance between S30V and LC200N is either poorly controlled (different edge geometry, sharpening is different, testing is inconsistent, etc) or the dominant edge dulling mechanism is not wear, such as edge deformation.First, S90V is made with a vanadium-based alloy while M390 contains a higher concentration of chromium. This gives S90V better edge retention than M390. However, M390 is easier to sharpen than S90V and has better corrosion resistance. In terms of hardness, both steels fall in the high range on the Rockwell scale.S90v and M4 steel will go head to head today, and the winner will be revealed. Both S90v and M4 steel have the same degree of retaining edge. When compared to S90v steel, however, the M4 steel is inferior in toughness. Once again, the fact that M4 isn’t manufactured from stainless steel means it won’t hold up better to wear..
