What kind of steel is S35VN?
martensitic stainless steel
CPM S35VN is a martensitic stainless steel designed to offer improved toughness over CPM S30V. It is also easier to machine and polish than CPM S30V. Its chemistry has been rebalanced so that it forms some niobium carbides along with vanadium and chromium carbides.
Is it hard to sharpen S45VN?
One of the main limiting factors for polishing and sharpening is the amount of hard MC (vanadium or niobium carbides). With the similar MC content to S35VN, S45VN is expected to sharpen and polish similarly as well. And it should be somewhat easier to polish and sharpen than S30V.
How good is SPY27 steel?
The SPY27 held its edge quite well, roughly the equivalent of S35VN. It was also quite resistant to corrosion. After a bunch of cutting, it lost its hair-popping edge. So I took it to the Ken Onion Work Sharp, and after a few passes, the knife was back to laser-sharp.
Is CPM SPY27 stainless?
In close cooperation with Crucible® Industries, we have developed CPM SPY27, a particle metallurgy stainless steel containing a proprietary mix of alloys, including vanadium, molybdenum, niobium, nitrogen, and cobalt.
Is S35VN steel good steel?
S35VN steel usually has a Rockwell Hardness rating between 58 and 61, depending on the blade’s heat treatment. CPM S35VN steel’s high HRC rating makes it an excellent durable steel for everyday use in tough environments.
Is S45VN better than S35VN?
Is S45VN really better than S35VN? The answer may surprise you. Yes, it is a better steel than S35VN but there’s not a great difference. They basically are alike with the exception than S45VN has a little bit more carbon and chromium in the mix, along with the addition of nitrogen – which S35VN does not have.
Is S35VN hard to sharpen?
S35VN is a relatively hard steel, but can be sharpened with nearly any standard sharpening device. We’ll go over our preferred methods below, but a leather strop, ceramic rod, small sharpening stone or any other sharpening tool will work well.
Is SPY27 better than S30V?
While it’s wear resistance is slightly less than S30V, when the edge is maintained like most of us do, and non abrasive materials are cut, like most of us cut, SPY-27 will have noticeably superior edge retention.
Which spyderco steel is best?
CPM S30V is a hardened and sintered stainless steel, considered by many experts as the best blade steel in the world. H1 and LC200N are highly corrosion resistant, and used on Spyderco’s Salt series knives. A few are even coated in titanium carbon nitride (TiCN) for greater hardness and reduced friction.
Is S35VN good steel?
How strong is S35VN?
CPM S35VN knives are able to stand up to long-term use without diminished quality. S35VN steel usually has a Rockwell Hardness rating between 58 and 61, depending on the blade’s heat treatment.
What is the hardness of CPM-S35VN steel?
At a Rockwell RC hardness level of 58, it took 32 foot pounds of force to break the S35VN sample, higher than all of the other steels tested, including CPM S30V (at 58 HRC), S60V (at 56 HRC), S90V (at 58HRC), and 154 (at 60HRC), 420HC (at 58 HRC), and M390 (at 60 HRC) steels. This test measured each steel’s longitudinal toughness.
What’s the difference between S35VN and s45vn steel?
Bravo to them. S45VN is a steel that was developed by one of their metallurgists (Frank) as an improvement to S35VN. More incremental than revolutionary, but it did test well and we’re working with it. So improved corrosion resistance, and toughness and edge retention in between s30v and s35vn.
Which is better S35VN or Elmax steel?
On CATRA’s TCC (total cut cards) test, where the number of impregnated silicon cards cut by blades with each steel type are measured, S35VN scored a 707, higher than many steels including N690, A2, and 3V, while lower than others including ELMAX and M390. In addition to tests, S35VN steel used in various knives has won those knives numerous awards.
Which is better M390 or s45vn carbide?
“The reason that the somewhat better toughness result for 20CV and M390 is puzzling is because of the significantly coarser carbide structure. The finer structure of S45VN would be expected to lead to better ease in machining and sharpening and better resistance to chipping when compared with 20CV.
