If your preference is M390/20CV that is totally fine. #1.1084 carbon steel patinated fixie. Alternatively S35VN could be used for slightly better toughness but if toughness is a limiting factor there are steels with significantly higher values. It will not be as easy to finish as something like CPM-154 which is a favorite among custom knifemakers putting on hand-rubbed finishes. I used ThermoCalc to compare S45VN if the niobium were replaced with vanadium, i.e. Chromium carbides coarsen more rapidly than vanadium and niobium carbides in powder metallurgy steels so reducing the amount of chromium carbide helps with carbide size. However, nitrogen can also be intentionally added to the steel for higher amounts. S45VN has only slightly reduced toughness when compared with S35VN, and S45VN is an improvement over S30V, particularly when hardness is factored in: Elmax had somewhat better toughness though at lower hardness, when hardness is considered the toughness of S45VN is better. Re: CPM REX 45 | Edge Performance. Blade Style: Drop Point with finger flipper and thumb groove opening. It has Rick Hinderer's well-known Spanto blade, a practical … Blade length 3.775in. This version of the PM2 is a limited edition "Sprint Run" offering high performance … Top. Its chemistry has been rebalanced so that it forms some niobium carbides along with vanadium and chromium carbides. They’ll clean, oil, adjust, and re-sharpen your knife for free and even mail it back at no charge. S45VN has a higher content of chromium carbide compared with S35VN and S30V, with equivalent MC to S35VN but lower than S30V. Required fields are marked *. Therefore the corrosion resistance of S45VN should be improved relative to the earlier S30-series steels. Also m390 is still going to boast greater wear resistance/edge retention. Just ask Steve. ***One per household. Substituting niobium carbides for some of the vanadium … And it should be somewhat easier to polish and sharpen than S30V. 58-59 HRC. The results of these experiments (minus S45VN) were previously shown in this article. Blade Style: Drop Point with finger flipper and thumb groove opening.

An improvement in toughness with a higher austenitizing temperature was also seen with heat treatments of S35VN which likely behaves somewhat similarly (I do not yet have a separate article on S35VN): The toughness of S35VN was also found to peak at a tempering temperature around 350-400°F which may also help explain why the 2000-400 heat treatment led to the best combination of hardness and toughness: To investigate the cause behind the toughness increase with higher austenitizing temperature, I looked at the microstructure for the 1950-450 and 2000-400 specimens. Its carefully tuned chemistry promotes the formation of more chromium carbides while leaving larger amounts of free chromium available for corrosion resistance. This knife makes just as much sense in the back of your truck as it does in the kitchen drawer. Blade Steel: S45VN stainless Tool Steel with Black flutes running on Grade 10 stainless ball bearings. We expect a reduction in toughness when compared with S35VN because of the increase in total carbide content. To determine why the freezer led to similar hardness to liquid nitrogen, I used magnetic saturation to measure the amount of retained austenite. S45vn Sales. CPM S45VN. Crucible’s first major stainless PM steel was S60V, formerly called 440V, and the earliest record I can find of that steel is from 1983 [1]. There are three significant things to know about S45VN steel … So in your opinion. CPM® S45VN is a martensitic stainless steel specifically created to transcend its predecessors.

So….would you pick a perfectly heat treated s45vn knife over a perfectly treated s30v or s35vn of the same knife? I mainly choose m390/20cv/204p for folders I edc, because it seems like it’s the best option out there right now. One of the main limiting factors for polishing and sharpening is the amount of hard MC (vanadium or niobium carbides). That shift in favored carbide types improves wear resistance by having more of the harder vanadium/niobium carbides (MC) and also improves corrosion resistance because less chromium carbide (M7C3) is formed: In the article about niobium additions, I wrote about how niobium is a stronger carbide former than vanadium, leading to hard niobium carbides even in high chromium steels. Vanax has higher toughness than S45VN, being similar to S35VN when adjusted for hardness.

Spyderco. These carbides are harder than standard abrasives which is what makes polishing more difficult. S45VN is a new powder metallurgy stainless steel being produced by … Perhaps even higher hardness could be obtained by austenitizing at yet higher temperatures. In this case with S45VN the carbon in solution is not particularly high and the high carbide content means that grain growth is minimal, so the reduction in carbide content with higher temperature led to an improvement in toughness. I saw s30v as a good mid range folding knife steel and s35 as a good mid range fixed(5-6 inch) blade steel, but nothing really stands out about them. The knife is very light and an awesome cutter, perfect for small to medium tasks. My recommended heat treatment for S45VN is 2000°F austenitize along with a fast quench and a cold treatment followed by a 300-400°F temper depending on desired hardness. As noted in the niobium article, small additions of niobium can also improve toughness by refining the microstructure as a whole by changing the sequence of solidification. CPM S35VN is a tougher version of the popular CPM S30V, due to the addition of niobium. Handmade in Escanaba, Michigan. His first Spyderco collaboration faithfully translates this novel design into a unique production folder with a hollow-ground CPM S45VN blade, a bead-blasted titanium handle, a Reeve … Spyderco Barong - $879.99. Is s35vn tougher vs m390? I suspect that those samples (austenitized at 2140°F) have relatively high retained austenite which can help with toughness but is not always desirable. So I would choose S45VN for higher edge retention and corrosion resistance and S35VN for better toughness, depending on your desired properties. Replacing niobium with vanadium leads to a reduction in MC (niobium and vanadium carbides) and chromium in solution (corrosion resistance), and an increase in undesirable chromium carbide (M7C3), in a somewhat similar fashion to nitrogen.
