Crucible CPM® Rex® 121® powder steel

CPM® REX® 121 (Crucible Industries LLC) is a high-vanadium-cobalt tool steel designed to achieve the high wear resistance, hardness and reddening characteristic of high-speed steel. Its excellent red resistance (red resistance is a characteristic of the heat resistance of steel, which means the ability of steel to retain high hardness and wear resistance obtained as a result of heat treatment when heated to red tempering temperatures) ensures a higher cutting speed compared to other high-speed cutters. Excellent wear resistance (due to the high vanadium content) helps maintain the sharpness of the edge at high cutting speeds.

Powdered high-speed steel was developed at the end of the 60s of the last century in Sweden. The method of powder metallurgy allows introducing a larger number of alloying elements into steel, while there is no decrease in strength and machinability.

Powder steel, unlike ordinary steel, is fed in molten form through a special nozzle through a stream of liquid nitrogen. Steel quickly hardens in the form of small particles. The result is a powder with a uniform arrangement of carbides (the place of accumulation of carbides is the nucleation of cracks). Carbides in steel perform the same function as stones on the street: they (carbides) are harder than the steel that surrounds them, and contribute to increasing its wear resistance.

The resulting powder is sifted and placed in a steel container in which a vacuum is created. Next, the contents of the container are sintered at high temperature and pressure - in this way, the homogeneity of the material is achieved. This process is called hot isostatic pressing. After that, the steel is processed by pressure. The result is a high-speed steel with very small particles of carbides evenly distributed in the steel base. The obtained steel can be rolled in the traditional way, as well as serial grades of steel, as a result of which its increased strength is achieved.

Differences in wear resistance indicators of different brands of powder steel are explained by the presence in their composition of different carbides in different proportions and with different uniformity of distribution throughout the volume of steel. Of two steels that have approximately the same hardness, the one that contains more carbides or is harder will be more wear-resistant.

CPM REX 121 fills the gap between high-alloy tool steels and carbide materials (tungsten carbide, second only to diamond in hardness). Can be used in cutting tools where high cutting speeds require higher heat resistance, but the carbide tool is too brittle, or in tools with high wear resistance (stamps) where the carbide tool is also very brittle.

CPM Rex 121 was developed in 1998. In terms of hardness, it is truly a champion, capable of reaching a hardness of 70-72 HRC. The official Rockwell C scale has a maximum value of 70 HRC.

Also extremely high wear resistance. Difficult to grind and therefore difficult to sharpen. Sharpening this alloy can be a nightmare even at 68HRC, and it will be exponentially harder at higher hardnesses. With such a large number of alloying elements, many carbides have formed, and some of them are not very small. The steel works better with a rough sharpening (the photo below shows a comparison of the microstructures of popular steel brands and the microstructure of CPM Rex 121).

There are many hard steels in the world, but according to renowned master knife maker Gary Creely, the REX 121 takes them to a new level. "The steel has a low Rockwell hardness of 40 even after annealing, and after heat treatment it is close to 70 HRC." The steel is described as Crucible's answer to competing steel Carpenter CTS – Maxamet Micro-Melt Alloy. Although they are very similar in chemical composition, REX 121 contains 1% more carbon and 3% more vanadium. The practical result of this hardness value is unprecedented sharpness retention. REX 121 knives will far outperform even other high quality steels such as M4 and S35VN.

The steel is not very impact resistant and can break with abuse, but Creely believes that excellent edge retention is more useful than high strength in the small knives we carry every day. This steel is best suited for smaller knives. If the REX 121 finds its way to a larger blade, the chances of it being misused will increase dramatically.

The disadvantage of REX 121 is that it is so hard that it can damage ordinary abrasive materials. "In short, you need to use diamond abrasives to sharpen this type of steel," Creeley notes. "If you choose your favorite Japanese waterstone, there is a good chance that the steel will cut your waterstone harder than the stone will sharpen the steel."

Steel composition:

From 3.4% - the carbon content in the alloy is 3.4%. Carbon is the most important element of steel, it increases its strength and gives the metal good hardness.

Сr 4.0% - the chromium content in the alloy is 4.0%. Chromium is a grayish-white shiny hard metal. Chromium affects the ability of steel to be hardened, gives the alloy anti-corrosion properties and increases its wear resistance. It is contained in stainless steel of any brand.

Mo 5.0% - the molybdenum content in the alloy is 5.0%. Molybdenum is a silver-white metal. Molybdenum is a refractory element, it prevents brittleness and fragility of the blade, giving it the necessary rigidity, making it quite resistant to high temperatures.

V 9.5% - the content of vanadium in the metal is 9.5%. Vanadium is a grayish-white shiny metal that has great hardness. It is responsible for elasticity and strengthens the properties of chromium, gives the metal inertness to aggressive chemical environments.

W 10.0% C tungsten content in the alloy is 10.0%. Tungsten is a light gray metal. The most refractory metal has a melting point tpl = 3380 °С. It is used to create alloys with high strength. Tungsten is used as one of the main components or an alloying element in the production of high-speed steels.

Co 9.0% - the cobalt content in the metal is 9.0%. Cobalt is a silver-white, slightly yellowish metal with a pink or bluish tint. Increases heat resistance, improves mechanical properties. Machining tools are made from alloys using cobalt: drills, cutters, etc. etc.

S 0.03 - 0.12% - sulfur content in metal - 0.03 - 0.12%. Sulfur, like phosphorus, belongs to harmful technological impurities in steels and alloys. Increasing the sulfur content significantly reduces the mechanical and physico-chemical properties of steels, in particular, plasticity, impact toughness, abrasion resistance and corrosion resistance. The limits of sulfur content as a technological impurity are 0.035...0.06%. Due to the extremely fine and homogeneous microstructure of SRM (Crucible Particle Metallurgy proprietary technology process), if desired, sulfur can be added to improve machinability. A higher sulfur content benefits the tool maker by making it easier to manufacture and the tool user by making it easier to resharpen. The CPM process ensures that the additional sulfur will not affect the strength of the tool.

G10 — in Pavel Honcharenko's handmade knives: quality, style, modernity
What kind of material is this?
G10 is a light and hard material characterized by a textured surface and special practicality. It is used to create handles on various types of knives - complex and integral, with additional elements.

The basis is a compound reinforced under pressure with fiberglass. The fibrous structure gives the material rigidity. In order to increase the important operational characteristics during the manufacture of handles, special strengthening chemical compounds are additionally added to the composition. The material is non-combustible, has higher strength characteristics - for bending, tearing and impact.

G10 is formed in layers. This allows you to paint the overlay in one or more colors, creating interesting visual effects of the product's multi-layering. Outwardly, it resembles micarta - another popular material from which the sheaths of RoS handmade knives are made.

Features of the production of overlays with G10
Most manufacturers subject finished G10 pads to sandblasting, which exposes the structure of the fiberglass. As a result, the handle acquires a rough surface, which prevents slipping in the hand and ensures comfortable and safe use of knives. After the finishing treatment, the surface of the pad may become dull. To restore a bright, spectacular appearance at the last stage of production, it is covered with oil or polished.

The craftsman uses G10 handle pads with various knife steels - ATS 34, CPM154CM, D2, 440C, CPM S30V, 40X13.

Advantages of the material
This modern material has the following advantages:

• easily withstands flexibility and stretching loads;
• has resistance to shock loads;
• does not absorb moisture;
• differs in high density;
• resistant to radiation and chemicals;
• has low electrical conductivity;
• does not dry out and does not deform;
• resistant to high temperatures.

Another advantage of this material is an excellent ratio of mechanical strength and light weight. This makes it possible to obtain strong linings with good operational characteristics that do not burden the knives.

High-quality and original inserts made of G10 became a wonderful decoration of exclusive and unique Studio knives Pavlo Honcharenko's Handmade Knives Studio (Ukraine), which offers to order and buy online store https://knife.net.ua

Stabilized Ash Suvel

RESINOL, Stabilization of wood - a method of processing, as a result of which the wood is given higher strength and improves its decorative qualities, while preserving the natural pattern. That is, stabilized wood combines the advantages of synthetic materials with natural natural beauty. In the course of stabilization, the wooden workpiece seeps through, forming a polymer monolith that securely binds the wooden components and minimizes harmful factors affecting the human body (you can familiarize yourself with the list of harmful factors encountered during the manufacture and operation of wooden products HERE). Stabilized wood has excellent mechanical properties during processing - there are no differences in density along the body of the workpiece (which allows more accurate drilling and sawing), it is polished without clogging the skin, it is polished to a mirror. At the same time, the appearance and tactile sensations remain inherent to ordinary wood.

In addition to the intricate pattern on the surface of the product, stabilized wood provides a number of undeniable advantages over traditional materials:
• High density;
• hardness;
• Resistance to changes in temperature and humidity of the environment;
• Immunity to ultraviolet radiation;
• Ability to withstand short-term heating by an open flame, without losing its quality characteristics and without being deformed;
• Impermeable to various liquids, including oils;
• Resistance to solvents of organic origin;
• Excellent decorative properties – stabilized wood lends itself well to manual and mechanical processing (does not clog sandpaper).

Bars of stabilized wood are often used to make knife handles and other cutting tools. Stabilization, as a rule, increases the weight of the workpiece up to one and a half times (depends on the wood), so a well-finished bar should sink in water.
As raw materials for stabilization, sawdust, sawdust, and sapwood of various deciduous tree species are most often used.
             A cap is a rounded growth on a tree (trunk or branches), filled with small wooden nodules of dormant (overgrown, but not developed) kidneys. Many branches often grow from such growths. Since each such kidney has a formed ring-like embryonic structure, a cut of such wood has a characteristic "malachite" texture, which looks very beautiful on handles, especially if it is "revealed" with the help of impregnations and dyes. Cap carving is rarely used because the carving pattern is superimposed on the wood texture pattern.
             Souvel is a type of wood with structural changes in the fibers other than kapa. Kidneys and ring structures are missing from the picture. In fact, the wood of suveli has a curved wavy-linear texture (from the Old Russian "svyl" - twisted), which is formed by twisting the tree itself, twisting the annual rings of the tree. Therefore, the pattern of the souvel is less intense and saturated than that of the capa, usually represented by simply curved lines of wood fibers, this texture does not overshadow the carving elements on the handle.
            Both sapwood and sapwood are very hard woods, especially sapwood, and are well suited for making handles not only because of their beauty.
            Split is another wood pathology that is often used to make knife handles. Split is the result of life activity of flexible colonies or bacteria on wood, which forms colored spots or streaks uncharacteristic of the breed. Often, different types of fungus are specially planted, for example, on beech or maple to obtain affected wood. Split reduces the strength of wood and worsens its properties, therefore, wood affected by the fungus is used only in a stabilized form.
