Knife Steel . . . Know Your Options!

To corrode or not to corrode, that is the question. In fact, that is only one of the questions. To hold a tremendous edge, or not to keep a fantastic edge happens to be another important issue! Numerous customized knife makers are finding middle ground for those two concerns.

High carbon and also stainless steels usually are equally satisfactory if appropriately alloyed. The high carbon steels are typically the steels which have been forged. They can be differentially tempered. This specific property gives the knife maker far more options. He can much better influence the hardness having to do with the cutting edge, and furthermore , still enjoy a tough knife with a springy back.

We will look at for starters, some of the more established carbon knife steel available.

10xx Series

1095 is among the most well-known steel regarding knives. It's a very simple steel comprising.95% carbon, and.4% manganese. Alternative 10 series steels are used for knife making for instance 1084, 1070, 1060, and 1050 etc. Each of these steels are decreasing in carbon content, and thus are also decreasing in wear resistance. At the same time, being the carbon content goes down the toughness increases. So ,, a lot of the lower carbon content designations tend to be more commonly used for swords.

O-1

O-1 steel is a different high carbon steel which will gives razor sharp edges however, it dulls easier than A2 Steel. O-1, just like A2 has a 1% carbon content. It consists of 1.35% manganese,.5% chromium,.35% silicon, and.5% tungsten. O-1 steel might be more forgiving to people who find themselves quite a bit less proficient in getting a good edge. To sum up, it is always easier/faster for you to hone to a razor razor-sharp edge than a number of the other choices, but is not going to stand up to abuse as nicely. O-1 is really liked by forgers together with bladesmiths. It really is tough, although not as tough as 5160.

L-6

L-6 is very similar to O-1. It really is in essence band saw steel. It is maybe the top end steel for your knife whenever maintenance is not really a concern. It rusts very easily, nonetheless maintains a great edge very well. Additionally it is pretty tough. It can be a preference of forgers.

W-2

W-2 is kind of tough and maintains an edge well as a result of its.25% vanadium. What's more, it has.25% manganese, and silicon. It's not necessarily as widely used or well-liked.

A2

A2 steel is practically a stainless steel. With (5%) it does not posses quite a satisfactory amount of chromium. It's got 1% carbon,.6% Manganese, 1% molybdenum, and.2% Vanadium. It's not at risk from corrode. A2 steel is preferred regarding combat knives because of its strength. The strength with the edge of the A2 steel can be improved upon by cryogenically treating the blades at -320 degrees Fahrenheit. A2 steel is much harder when compared to O-1 carbon steel and although more difficult to sharpen, it retains a good edge longer. It works most desirable somewhere between 30 and 35 degrees. The trouble with A2 steel is the fact that it tends to fracture easier when the bevel is ground below 30 degrees. A2 is more robust compared to D2 and M2, nevertheless has a lesser amount of wear resistance.

M2

M2 Steel is actually a fine-grained molybdenum/tungsten high-speed tool steel. It provides.85% carbon,.25% manganese, 4.2% chromium,.30% silicon, 5% molybdenum, 6.35% tungsten, and 1.9% vanadium. It's an very good alternative with respect to increased temperature uses. For example, the annealing temperature of M2 steel is about 1000 F. It is to some degree more " heavy-duty " and even more wear resistant compared to D2, nevertheless, M2 rusts easier.

D2

"D" series steels are actually classed as cold work tool steels. D2 steel can be described as top quality tool steel. With 1.5% carbon content It is better for retaining an edge than a reduced amount of exotic stainless steels. D2 contains a reasonably high chromium content (11.5%) which is often referred to as a "semi-stainless". It is a well recognized, air hardened, high carbon, high chromium tool steel. There is 1% molybdenum, and.9% vanadium. It offers incredibly high wear resistance qualities. D2 steel is among the toughest knife blades you'll find, and it is a favorite of the best specialized knife makers. Those who have ever made use of a very good D2 steel blade while in the field, raves about the steels cutting ability, strength, together with edge retaining properties. In other words, D2 steel can easily produce among the best blade stocks obtainable for a functioning knife.

5160

5160 steel is a type of spring steel. It is essentially 1060 with 1% of chromium added to make it deep hardening. It is made use of in swords, axes and also other high-impact tools. 5160 Steel is favored these days for many knife kinds, nonetheless is usually put to use in larger blades that require more longevity. It is actually quick and easy in order to sharpen, and, when resistance to side to side forces comes into play, 5160 s really a champion.

50100-B

50100-B is a AISI designation of the same steel as 0170-6. The B designates vanadium has been added. This steel is an excellent chrome-vanadium alloy that is comparable in elements to O-1, however it is noticeably more inexpensive. It is essentially 52100 with 1/3 not as much chromium.

52100

52100 is sometimes in contrast with 5160. It offers a bit more carbon content than 5160, and thus keeps an edge much better. It isn't as durable however. The tradeoff is due to wear resistance. A lot of hunting knives are now made out of this particular steel.

At present, let us consider the alloys of stainless regarding knife steel.

Stainless steel can be designated as such if it's got over 13% chromium. Nonetheless, the ASM Metals Handbook says that it merely has to be over 10%. There are numerous quantities tossed around. This variation though, may perhaps be due to the measure of free chromium accessible. There are lots of stainless alloys with varying corrosion-resistant components making it an outstanding material for knife blades.

420 and 420HC

420 is an extremely soft steel because of the less than.5% carbon content. It won't hold an edge effectively, but it is especially stain resistant, and it is often used for more affordable knives. Additionally it is often utilized to make diving knives. 420 HC is adapted to be more like 440A by including more carbon.

440A, 440B, and 440C

This series of steels will increase in carbon content from A -.75%, to B -.9%, to C - 1.2%. 440C steel, if hardened correctly, is an excellent knife steel. It is rather tough, and has good edge holding features. It does not hold an edge as good as ATS-34, but is a lot more stain resistant. This complete series is extremely rust resistant. 440A is most rust resistant, and 440C the least.

AUS-6, AUS-8, and AUS-10

This is a Japanese series of steels which roughly compare with the above mentioned 440 Series. The carbon content increasing from AUS-6 -.65%, to AUS-8 -.75%, to AUS-10 - 1.1%. AUS-6 would much more closely rival the less costly low-end 420. AUS-8 is really a middle level steel like GIN-1 or ATS-55. AUS-10 competes with higher end steels, and typically compares well with 440C. It has somewhat less chromium than 440C, but all 3 steels of this series have vanadium added. Vanadium increases the wear resistance and the grain, which gives these steels the ability to be sharpened to a incredibly fine edge. Vanadium also improves wear resistance. These steels are often referred to as 6A, 8A, and 10A.

GIN-1

GIN-1, also referred to as G-2 compares commonly to AUS-8, and ATS-55. It offers less carbon, and a smaller amount molybdenum than ATS-34. It's a little higher in chromium, and usually is used for the more inexpensive knives.

ATS-34

ATS-34 steel is globally regarded for its edge holding and taking abilities. It is a Japanese steel that favorably measures up to the U.S variation, 154 CM, which is not nearly as popular. ATS-34 is definitely tougher than 440 steel so breaking the tip with this steel is going to be less likely, but it isn't as rust resistant. ATS-34, is usually, either cold or hot rolled depending on its thickness, but both are likely annealed (heat treated).

ATS-55

ATS-55 is a grade behind ATS-34, simply because it does not have molybdenum. Minus the molybdenum, it doesn't hold an edge as well, and is quite a bit less resistant to rust, and it has less wear resistance. It compares favorably with GIN-1, and AUS-8

BG-42

BG-42 is gaining popularity. Additionally it is costlier than ATS-34, which may limit its popularity. Due to the addition of vanadium, and double the manganese as ATS-34, it will hold a significantly better edge, and will also have much better strength than ATS-34. It is a little harder to work.

S30V, S60V and S90V

This series of steels is packed with a greater number of alloys because of the particle metallurgy process that is quite different from standard steel producing methods. These are high vanadium knives, and compare favorably with BG-42. They're possibly more wear resistant than any other stainless steel. However, they're a lot more expensive than BG-42, and even more challenging to work. This relegates them largely to the experienced custom knife maker world. S60V is often referred to as CPM T440V, and S90V as CPM T420V.

Whether in need of an easily maintained knife, or perhaps a knife that holds an awesome edge, having the alternatives available may provide you with the best of both worlds.
