So we can understand more the Steel, let’s see its chemical composition. However, it is also controlled by carbide size and I do not have any micrographs of the new steel. And sharpening is probably a bit easier to S35VN. The resulting steel is expected to have similar hardness and corrosion resistance to S30V and S35VN. An alternative to r/knives. You can read about edge retention and predicting it based on carbide content and hardness here. As the original was a smaller, lighter version of the popular Paramilitary 2, this model is even lighter. Unfortunately, I am probably unlikely to get flatstock for experiments due to the steel being exclusive to Spyderco. I’d love that Nightstick too, if it was a higher steel grade. The vanadium was reduced to 2% relative to S35VN. The Astute looks like an interesting shape from a budget perspective. You can see my corrosion resistance rating in the table below: This is a pretty decent corrosion resistance, similar to Elmax (7.8), but is below steels like S45VN (8.4), M390 (9.1), and Vanax (10). The SPY refers to Spyderco and 27 is the atomic number of cobalt [2]. AREX HANDGUNS Anticipating the needs and recognizing the preferences of the user has been our major objective, resulting in a universally suitable self-loading pistol.

For comparison with other alloys open steel composition graph builder & analyzer. I mounted my dual illuminated RMR to test it out. Here is a chart of other steels to compare with S35VN: With similar MC carbide content (NbC + VC) to S35VN and S45VN, SPY27 would be expected to sharpen similar to those two steels. If you’re looking for all all-around best knife steel, you’d be hard-pressed to find one better than Bohler Uddeholm M390. Spyderco is known for using a huge variety of modern steels across their catalogue. REX 45 will have better edge retention but less corrosion resistance. I love the ha para 3 with s45vn steel but I might shot for the rex and Blade swap, I’m gong para 2 in s45vn since I just got the para3 in s110v and think imma go for the rex45 on the para3 lw over the spy27. The Cr and Mo addition provides corrosion resistance, hardenability, and secondary hardening. You can read more about niobium in this article. That ladybug in K390 just seems excessive. REX 45 will have better edge retention but less corrosion resistance. There is also a small nitrogen addition which is made to increase hardness and corrosion resistance, as described in this article. The steel is reportedly exclusive to Spyderco. Each can reach approximately 64 Rc though are generally tempered down to the 58-61 Rc range depending on the manufacturer and heat treatment. The blade features a full … Clicked the link thinking I'd see a knife I would I want but I reallllly want that rocks glass. Now they've gone a step further and created their own proprietary steel composition via Crucible Industries. See the edge retention prediction chart to see the expected carbide volume of SPY27 which came in under S35VN, S30V, S45VN, and Super Gold 2, and is also lower than Elmax and M390 which are not shown in the table. I'm curious about that Spy27 steel and the Rex45! Thanks to my friend Jerry for lending me his spare T.REX Offset Mount to check out. T.REX Offset Mount.

Hopefully we will be able to learn more as knives are released. Niobium carbides have also been found to help refine the microstructure of steel. REX 45 is similar to HAP40, SPY27 supposedly will be more like S30V/S35Vn. The MC carbides are harder than most common abrasives apart from diamond and CBN, so lower MC content leads to easier sharpenability. CPM SPY27 is a steel produced by Crucible exclusively for Spyderco. CPM REX 45 is a new steel to me. Therefore I would expect SPY27 to have toughness at least as good as S35VN and probably better, but that would have to be confirmed experimentally. REX 45 is similar to HAP40, SPY27 supposedly will be more like S30V/S35Vn. Some of these are up for preorder at BladeHQ. You can see more ratings in the corrosion resistance article I linked to above. Short of purposeful abuse, it’s all but impossible to chip an edge on an INFI blade. The edge retention of SPY27 is expected to be a bit below S35VN, similar to Super Gold 2, though higher than steels like VG10, 440C, and CPM-154.

Looks like you're using new Reddit on an old browser. Metallurgy and Testing of Knives and Steel. $155.00. The Para 3 Lightweight takes the concept of the original Para 3 to a whole new level. The cobalt addition increases secondary hardening when tempering in the upper temperature range, which I have written about previously here and here. According to crucible: “CPM REX 45 is an 8% cobalt super high speed steel which has excellent hot hardness along with good wear resistance and toughness, making it suitable for difficult machining applications.” A data sheet. The ease or difficulty in burr removal would be more based on the heat treatment, particularly when it comes to retained austenite, as lower retained austenite makes burr removal easier. You could get a simple 45-degree offset Picatinny rail but dedicated mounts are more streamlined and less bulky. https://www.patreon.com/Knifesteelnerds, Click to share on Twitter (Opens in new window), Click to share on Facebook (Opens in new window). 4 product ratings - Spyderco Shaman Folding Knife CPM-REX 45 Satin Plain Blade, Burnt Orange G-10.

The Nb content was bumped up to 1% from the 0.5% of S35VN and S45VN which will of course increase the amount of niobium carbide. It is always interesting to see what the numbers predict and it will be cool to see how they play out once you get some to do some real in hand testing. Brand New. I have previously performed corrosion resistance experiments and related it to predicted chromium and other alloying elements “in solution,” as you can read here. All things pocket knives. Plan on getting one of the lightweight para 3s just can’t decide which. The 1% niobium content may help refine the overall carbide structure when compared with 0% or 0.5% Nb PM stainless steels.

Speaking of S45VN, it is somewhat surprising that this steel has been announced so shortly after that steel being announced and released. The two steels aren’t related really. Your email address will not be published. In general, lower carbide volume means higher toughness. Maxamet is a non-stainless high speed steel capable of high hardness. How is it related to MAXAMET ?vObviously I understand it is not as hard but what about the overall quality? Based on the predicted alloy in solution for SPY27 it should have similar corrosion resistance to S30V and S35VN. Spyderco Manix 2 Lightweight BD1N Black FRCP C101PBK2 ...

Manix 2 Lightweight CPM SPY27. or Best Offer +$5.95 shipping. The steel has the same Cr and Mo content as S30V and S35VN. Here are some experimental results of different steels for CATRA slicing edge retention to get a feel for where SPY27 may sit: Toughness of steel can be difficult to predict based only on composition or carbide content. The second model to come out with the new SPY27 steel is the Manix 2. The carbon content is of SPY27 is balanced to result in a similar hardness to S35VN, S30V, and S45VN, as indicated by carbon in solution estimates from Thermo-Calc: Therefore we would expect the steel to reach a similar hardness to those other CPM stainless steels. The steel looks somewhat similar to S35VN but with increased Nb and N, decreased C and V, and a 1.5% cobalt addition. Though it should be a little easier to abrade away steel because of the lower chromium carbide content (M7C3). Model # SP-C101PCBL2 . The steel looks somewhat similar to S35VN but with increased Nb and N, decreased C and V, and a 1.5% cobalt addition. I estimated edge retention for a hardness of 61 Rc. Steel is a combination of iron and carbon with other elements. I used carbide contents from Thermo-Calc to estimate CATRA edge retention relative to 440C at 58 Rc (100%). Update 3/10/2020: We did a range of experiments with SPY27 to supplement the estimates in this article. Spyderco Manix 2 Lightweight SPY27 Mineral Blue FRCP Folder C101PCBL2 . It may be that the reduced carbon content when compared with S35VN leads to superior toughness. The edge retention is likely a small step down from S35VN. The edge retention is likely a small step down from S35VN. That’s very interesting. Being a little bigger than the Para 3 and utilizing the strong ball bearing locking mechanism and light weight FRCP handles this is sure to be a great knife. Required fields are marked *.
