CPM S30V is a powder, martensitic (high carbon) stainless steel developed by Dick Barber of Crucible Materials Corporation in collaboration with renowned knife maker Chris Reeve. The chemical composition of the steel contributes to the formation of a larger amount of vanadium carbides (in the composition of vanadium steel - 4.00%), which are more efficient in cutting than chromium carbides. Vanadium carbides give the grain of the steel structure a more uniform appearance, which improves cutting and strength properties. Despite the difficulty of hardening CPM S30V steel, knightmakers use it because it is easier to grinder than other powder steels. Composition: C-1.45%, Cr-14.00%, V-4.00%, Mo-2.00%. Steel is often used by almost all leading knife manufacturers: BUCK; EMERSON; CHRIS REEVE; STRIDER KNIVES; SPYDERCO and others.


 Steel R2. Among the many technological secrets that nightmakers hide from each other, as a rule, the main secret is the composition of the steel, the process of its creation and the method of hardening it. In Europe and America, with their developed system of patents and registration of rights to inventions, the secret of a particular brand of steel ceases to be a secret from the moment of registration of the right in the patent office. If another manufacturer needs a similar steel, then he slightly changes the composition of the original steel and gets a product similar in characteristics. In Japan, things are different. If any master manages to achieve the ideal (in his opinion) composition of steel, then he makes such steel on his own and does not reveal the secret of its composition. If it is not possible to independently produce such steel (lack of capacity for the required volume, labor intensity of production outside the steel mill, lack of a chemical laboratory, etc.), he concludes an agreement with a steel company, and this secret is passed down from generation to generation and belongs only to his family or proxies. ...

This type of steel is R2 steel, which is used by only a few knifemakers in the world. One of these masters is called Mr. ITOU (Hiroo Itou) and Mr. Tanaka. It is known to be powder steel. Some models use damask covers made from Japanese 420J2 steel.

Those who have knives from these masters unanimously claim that the blades have amazing sharpness, are not subject to corrosion and remain sharpened for a long time. This type of steel is produced by the Japanese concern Kobelco (Kobe Steel Group, Ltd.) and it is still not known exactly who owns the rights to the R2 steel composition, master Mr. ITOU (Hiroo Itou) as the first person who began to make knives from this steel or the Kobelco concern.

There is also an unconfirmed version that KOBELCO's R2 steel, under the name SG2, is being sold to Takefu. At the same time, blades from R2 are machined with an abrasive wheel at low speeds and with water cooling, and blades from SG2 use stamping - therefore, knives made of the same steel can work in different ways. In turn, Henckels designates SG2 steel on their knives as MC63, Fallkniven as 3G or SGPS

Chromax steel is a new knife steel with superior properties. It is a semi-stainless steel that sharpens well and has excellent retention. The Takamura brothers decided to make a line of knives that have outstanding cutting performance and achieved outstanding results. Chromax is composed of 5% chromium, 1% carbon, 0.9% manganese, 1.2% molybdenum and 0.5% vanadium. The steel is much less reactive than real carbon steel, but gives a lot of the same characteristics to some of the best carbon steels such as Aogami Blue Paper # 2. The steel has a hardness of 64-65 Rockwell.

Steel HAP40. Cobalt-alloyed tool high speed powder steel manufactured by Japanese metallurgical company Hitachi Metals ltd. The addition of cobalt makes the structure of the alloy homogeneous and improves mechanical properties. The alloy contains a generous amount of tungsten, molybdenum, vanadium, due to which it has exceptional toughness and high abrasion resistance, making it an excellent material for making knives.

Steel can be processed for hardness up to 66 HRc, due to which the high content of the carbide phase (including high-hard carbides MC) has high wear resistance with decent mechanics. Among the disadvantages are the complexity of heat treatment, the tendency to decarburization and scale formation, poor grindability, especially with fine abrasives.

This steel is highly corrosive in a humid environment, therefore it requires careful maintenance, either the blade must have an anti-corrosion coating, or a laminated structure (3-layer blade with a hard core and rust on the sides), either it must be chained in stainless steel plates.

The manufacturer positions HAP40 as one of the best modern steels for making high quality kitchen knives. Kitchen knives made from this steel are renowned for keeping their cutting edge sharp for a surprisingly long time. Recently, it has been gaining popularity on high-end designer knives.

Steel composition: C 1.27 - 1.37% - the carbon content in the alloy is 1.27 - 1.37%. Carbon is the most important element in steel, it increases its strength and gives the metal good hardness.

Cr 3.7 - 4.7% - the chromium content in the alloy is 3.7 - 4.7%. Chromium is a greyish-white shiny hard metal. Chromium affects the hardenability of steel, gives the alloy anti-corrosion properties and increases its wear resistance. Contained in any grade of stainless steel.

Mo 4.6 - 5.4% - the content of molybdenum in the alloy is 4.6 - 5.4%. Molybdenum is a silvery white metal. Molybdenum is a hard-melting element, it prevents brittleness and brittleness of the blade, giving it the necessary rigidity, making it sufficiently resistant to high temperatures.

V 2.8 - 3.3% - the vanadium content in the alloy is 2.8 - 3.3%. Vanadium is a grayish-white shiny metal with great hardness. It is responsible for the elasticity and enhances the properties of chromium, makes the metal inert to aggressive chemical environments.

W 5.6 - 6.5% - the tungsten content in the alloy is 5.6 - 6.5%. Tungsten is a light gray metal. The most refractory metal, has a melting point tmelt = 3380 ° C. It is used to create alloys with high strength. Tungsten is used as one of the main components or alloying element in the production of high speed steels.

Co 7.5 - 8.5% - the content of cobalt in the alloy is 7.5 - 8.5%. Cobalt is a silvery white, slightly yellowish metal with a pinkish or bluish tint. Increases heat resistance, improves mechanical properties. Working tools are created from alloys with the use of cobalt: drills, cutters, etc. etc.

ZA-18 - Japanese steel produced by Aichi Steel. The company recently developed this steel to improve upon the well-known VG-10 steel. The steel is hardened and then cryogenically treated (cryogenic hardened) to convert the remaining austenite to martensite. Hardness of steel 60-61 HRC. The chemical composition of ZA-18 is similar to that of VG-10 steel, but contains more carbon (1.20% versus 1.05% for VG-10), Chromium (18.0 versus 15.5), Molybdenum (1.50 versus 1.20) and Cobalt (1.8 versus 1.5) for greater hardness, strength and corrosion resistance.

 TOOL DOMESTIC STEELS:

KhVG (9KhVG) refers to non-heat-resistant steels of high hardness for cutting tools. Blades made from it are relatively easy to manufacture (due to low deformability during quenching), are easy to sharpen and have a significant margin of cutting edge durability. Strong. Corrosion resistance is weak, so they are chrome plated or blued.

H6VF in Russia is used for stamps and hand saws. Blades made of such steel have very good strength properties in combination with the resistance of the cutting edge. Satisfactory corrosion resistance If you are interested in a short hunting blade or a knife for fighting, this steel is for you.

5XHM. Even more durable than Kh6VF, and has good cutting properties. This steel is used for band saws. Technologically advanced. Strong even at low temperatures. Anti-corrosion properties are weak. Optimal for a knife of survival and extreme tourism - with a minimum of care, you can safely rely on a blade made of such steel in all life conflicts.

U10, U11, U10A, U11A and high viscosity U7A, U8A, U7, U8. non-heat-resistant tool steels of high hardness. These steels are used for hand tools, stamps, measuring tools and files, which are usually forged into blades. The notch marks left on the blade from the file give them a special charm. These grades provide sufficient strength combined with good cutting performance. Corrosion resistance is weak.

P6M5 High-hardness heat-resistant tool steel, capable of "holding" hardening even in ultra-high temperatures and is used in mechanical engineering for high-performance cutting tools. Cutting edge retention is very good. Strong enough, but not strong enough to compete with the brands above. Little spouse. It is poorly polished - it is important to keep this in mind, since individual cutters polish knives by hand, and polishing a blade made of such steel can cost 50-60% of the cost of a knife. Corrosion resistance is weak.

50HGA - high-quality alloyed chromium-manganese spring steel - very popular among blacksmiths. Very viscous. Good cutting edge resistance combined with strength properties comparable to 5XHM make it an ideal material for long-bladed weapons and knives that require increased strength, including combat ones. Corrosion resistance is not too high, slightly higher than that of 5XHM.

ShKh15 Ball bearing steel is quite similar to 50KhGA in properties, except that it is chosen by those who have to sacrifice insignificantly in strength in favor of better cutting edge resistance. This steel is mainly forged as it is difficult to find straight strips from it.

X12M Tool alloy chromium steel is corrosion-resistant. Of course, not to the same extent as 4X13, but far superior to the brands listed above. Insufficiently high chromium content (11 - 12.5%) does not allow it to be classified as “stainless steel”. But on the other hand, in terms of cutting ability, it has no equal among ordinary and stainless steels. The strength is slightly lower than that of other steels of this class, but good cutting ability and corrosion resistance easily compensate for this disadvantage. Easy to polish. Technologically advanced.

High alloy stainless steels:

40X13 (45X13) has unique anti-corrosion properties, but the ability to keep sharpening is extremely weak. It can be recommended for the kitchen or for the needs of a diver, but a hunting knife made of such steel will bring a lot of disappointment. Such steel is usually used for inexpensive household knives, cutlery knives, cheap historical replicants on the wall, etc. Composition: C: 0.36-0.45%; Cr: 12.0-14.0%; Mn: ≤ 0.80%; Si: ≤0.8%; P ≤0.03%; S ≤0.025%.

 50Х14МФ - Stainless chromium steel, used for the manufacture of cutting tools (scalpels) in the medical and food industries.

Composition: C: 0.48-0.55%; Cr: 14.0-15.0%; Mn: 0.45-0.80%; Mo: 0.45-0.80%; Si: 0.20-0.50%; P 0.01-0.03%; S 0.01-0.025%; V: 0.10-0.15%

65X13 is not a varietal, but is widely used by industrial manufacturers for their models. With proper heat treatment, a blade made of such steel is able to please the owner with a good combination of corrosion resistance (it darkens without the formation of rust in an active environment such as tomatoes, citrus fruits, blood) and a decent cutting ability. Material for the blade of a good kitchen, tourist or fishing knife. It is easily sharpened even in the field "on a pebble". A good thermist can achieve very good results with this steel. Composition: C: 0.48-0.55%; Cr: 14.0-15.0%; Mn: 0.30-0.60%; Si: 0.30-0.60%; S 0.01-0.03%.

9X18 (95X18 and X18) is the most respected stainless steel. Good cutting edge resistance does not seem like a price to pay for the slight degradation compared to 65X13 corrosion resistance. Unfortunately, there is a very wide variation in the quality of the source material. Like any high-alloy steel requires special heat treatment modes, it loses to carbon and tool steels in strength. Road. It remains one of the most popular materials for both folding and conventional knives. Composition: C: 0.9-1.00%; Cr: 17.0-19.0%; Mn: ≤ 0.80%; Si: ≤ 0.80%; S: ≤ 0.025%; P: ≤ 0.03
