The same study found values for 61 Rc S30V at 149% and 61.5 Rc M390 at 179% [8], which are similar to those given by Crucible (though for 20CV rather than M390). S45VN pm2 (A) never cut, used, carried slightly off centered $170. 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. Also from reading it’s seems S45vn’s performance is HIGHLY dependant on its heat treatment. (NEW!) The combination of niobium and nitrogen helps to keep the chromium carbide content as low as possible to help offset the increase in chromium so good toughness is maintained. In that table S45VN would be an 8.4 based on the criteria specified, or 8.6 using the 2000°F austenitize I am recommending. I have an update on M390 toughness in this article: https://knifesteelnerds.com/2020/06/01/m390-steel-history-and-properties-and-20cv-and-204p/. These numbers are calculated using ThermoCalc software: The main changes we expect from S45VN vs S35VN and S30V are an improvement in corrosion resistance due to the increase in Cr of about 1%. S45VN is somewhat of an incremental advance but it does seem to be an upgrade overall vs the earlier S30-series steels. So using niobium instead of vanadium should lead to a refined microstructure in general in part because of modifications to solidification as well as reducing the amount of chromium carbide. Enter your email address to subscribe to this blog and receive notifications of new posts by email. I soaked the steel for 20 minutes, plate quenched between 1″ aluminum plates, and then gave a cold treatment, either in a household freezer or liquid nitrogen.

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]. I have diamond sharpeners. When comparing against steels in the same class, that is somewhat below the rating for Vanax (10), M390 (9.1) and S110V (9.1), but above the ratings for Elmax (7.8), S35VN (7.8), S30V (7.7), and S90V (7.4). Filter by Steel. But there are going to still be much better steels for the job in regards to folding knifes. It shows a better overall set of properties, I think, making S45VN a good upgrade to either S30V or S35VN. Nitrogen is not as prone to form chromium nitrides as carbon is to form chromium carbides, so nitrogen can often be added to steel for an increase in hardness without decreasing corrosion resistance. 20cm overall length (8 in) 11cm cutting edge(4.3 in) 4mm thick(0.19 in) made out of 1084 steel … Especially for folding knives. [1] Chilton’s iron age 226 (1983): p. vi. Read more about austenitizing and effects on properties here: Part 1, Part 2, Part 3. The overall carbide content controls to a great extent the toughness of the steel. S60V was a modification of the common stainless grade 440C by adding 5.5% vanadium with a corresponding increase in carbon. May 13, … The hardness measurements lined up relatively closely with those given in the S45VN datasheet. Therefore a Mo addition can be used for stainless steels with a bit lower Cr for an improvement in corrosion resistance. OAL 8.4in.

Instead, the nitrogen promotes the formation of vanadium and niobium carbide which also decreases the amount of chromium carbides. Crucible researchers found that if the Cr content was reduced from 17 to 14% that the amount of vanadium carbide formed is much greater and that this resulted in an increase in wear resistance for a given vanadium content: That reduction in Cr led to S90V stainless steel which has 14% Cr and 9% V. The steel was found to have a good combination of toughness, corrosion resistance, and very high wear resistance. OUT OF STOCK. Free shipping. It features a beefy blade made from CPM-S45VN that rides on a set of alpha bearings inside a 6061 aerospace aluminum frame. Using a freezer saw very little change in hardness when compared with using liquid nitrogen instead. You can read more about the interactions of different element in forming carbides in this article. The S45VN datasheet provides a number for CATRA edge retention relative to 440C, which it lists as 143%. Spyderco Paramilitary 2 Sprint Run with S45VN blade steel. The patent for S90V was filed in 1995 [2]. However, the datasheet has an asterisk next to the 143% value and says that it is “based upon market feedback.” These estimates should perhaps be treated with some suspicion as the S35VN datasheet has the same asterisk for its 145% value which puts it at the same level as S30V, but independent experiments put S35VN around 132% at 61 Rc [8]. CPM S45VN is the updated version of CPM-S35VN. 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. 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. Your email address will not be published. I found that the carbides were significantly finer by using the 2000°F austenitize which is a likely explanation for the improvement in toughness: While austenitizing temperature does lead to the dissolution of more carbide, this does not always lead to an improvement in toughness because grain growth is possible and with more carbon in solution there is a chance of embrittlement. ***One per household. Para 3 Grey scales BD1N steel (C) scale swap and sharpening $70 SOLD SOLD SOLD. Blade thickness .156in. So I would choose S45VN for higher edge retention and corrosion resistance and S35VN for better toughness, depending on your desired properties.

CPM S45VN. Crucible researchers used the same 14% Cr as S90V to best utilize the vanadium additions but also sought to improve corrosion resistance through an increase in molybdenum. see all. 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.
