Powdered steel Crucible CPM® S125V™
CPM® S125V™ is a high-alloy martensitic stainless tool steel manufactured by Crucible Industries (USA). The corrosion resistance of the alloy is comparable to ZDP-189, that is, it is quite high. Steel ZDP-189 contains 20% chromium versus 14% for CPM S125V. The amount of carbon is about the same. It would seem that 125ya should rust more, but in ZDP-189 much more chromium goes into carbides than in S125V, where vanadium also goes into carbides. As a result, the chromium content in the solid solution for both steels is not so different.

Recently, many knife manufacturers have abandoned the CPM S125V, primarily due to the complexity of the finish. Custom craftsman Phil Wilson (Phil Wilson) said that handmade satin S125V takes three times longer than for CPM 10V - one of the most difficult steels (more or less mass-produced).

The steel is made using the technology of amorphous metal alloys, better known among knife makers and hobbyists under the acronym CPM (Crucible Particle Metallurgy). The CPM process makes it possible to produce a very uniform, high quality steel that is characterized by superior stability, uniformity and toughness compared to steels from traditional heat production.

Powdered high speed steel was developed in Sweden in the late 60s of the last century. The powder metallurgy method makes it possible to introduce more alloying elements into the steel without reducing the 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 into small particles. The result is a powder with a uniform arrangement of carbides (the place of accumulation of carbides is the place where cracks originate). Carbides perform the same function in the composition of steel as cobblestones on the street: they (carbides) are harder than the steel surrounding them, and contribute to its increase in wear resistance.

The resulting powder is sieved 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 - thus achieving material homogeneity. This process is called hot isostatic pressing. The steel is then pressure treated. The result is a high speed steel with very small carbide particles evenly distributed in the steel substrate. The resulting steel can be rolled in the traditional way, as well as serial grades of steel, resulting in its increased strength.

Differences in the wear resistance of different grades of powder steel are explained by the presence of different carbides in their composition in different proportions and with different distribution uniformity throughout the steel volume. Of two steels having approximately the same hardness, the more wear-resistant will be the one in which there are more carbides or they are harder.

Steel composition:

C 3.3% - the carbon content in the alloy is 3.3%. Carbon is the most important element in steel, it increases its strength and gives the metal good hardness.

Cr 14.0% - the chromium content in the alloy is 14.0%. Chromium is a greyish-white lustrous hard metal. Chromium affects the ability of steel to harden, gives the alloy anti-corrosion properties and increases its wear resistance. Contained in stainless steel of any brand.

Mo 2.5% - the molybdenum content in the alloy is 2.5%. 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 12.0% - the content of vanadium in the alloy is 12.0%. Vanadium is a grayish-white lustrous metal with great hardness. It is responsible for elasticity and enhances the properties of chromium, makes the metal inert to aggressive chemical environments.

​ Olive wood (olives)

Olive wood is very decorative, heavy and dense. This is an excellent, albeit expensive, option for finishing work, creating decor items and veneer.

Olive (olive): main characteristics

The olive tree, or olive, belongs to the genus Olive, the Olive family. It is an evergreen plant growing in the subtropics. In our area, it is found in the southern regions, where there are no severe frosts. However, the olive tolerates frosts up to 13-15 degrees calmly.

The trunk of the tree is covered with gray bark, the branches are sometimes drooping, long and knotty.

Oliva is rarely higher than 12 meters in height, the diameter of the trunk does not exceed 0.8 meters. At the same time, there are few even areas on the trunk of an olive tree - the trunk is knotted, twisted, hollow. It is rare to find olive wood materials longer than 2 meters. This partly explains the high cost of olive wood.

The olive tree lives up to 100 years.

The olive tree (maso tree) is a noble, unique plant with many stories and myths associated with it. Olive wood  is distinguished by special characteristics, namely, heaviness, density, complex pattern and a large amount of oil in the composition of the wood.

Sliced ​​olive veneer  is supplied to us from the Mediterranean countries, which is the birthplace of the olive tree. In order to fully satisfy the client in terms of price-quality ratio, we offer three grades of olive wood sliced ​​veneer - A, B, C, as well as adjacent grades AB, BC. We strive to make the terms of cooperation with our partners as profitable and reliable as possible.

Olive wood (olives), the complexity of its processing

Olive tree (Masoinoe tree) , as wood is quite an expensive material, this is due to the fact that there are very few flat areas on the tree trunk. Usually an olive tree grows from 12 meters and above and is up to 0.8 meters in diameter. The trunk at the same time has enough knots, hollows and curvatures. Olive wood materials are very rare to find more than 2 meters. It is a complex process to process an olive tree, but the result is a beautiful look and quality.

Olive processing is labor-intensive and takes a certain amount of time, since the composition contains a large amount of oils, and this introduces additional steps in the production of veneer - bleaching and deresining the wood. The fibers of the olive tree are not evenly distributed, and this is also another difficulty in the wood processing process.

One of the stages of the processing process is the drying of wood, which takes a considerable amount of time, it is dried very slowly at a low temperature so as not to deform the wood in any way. The high density and hardness of the wood species make it difficult to cut, only high-quality tools and a professional approach are needed here.

Olive wood  also responds well to paints and varnishes. Water-based products are usually not used, as stains may remain on the material, in order to eliminate them, the surface must first be primed.

The main properties of the olive tree

Olive wood  has a wonderful range of colors, its main color is yellow-white, but thanks to the brown stripes, a unique decorative pattern is presented, which looks very attractive in the decoration of furniture products. At the same time, the wood is perfectly polished and after polishing it well, a beautiful shine of the material is obtained.

Olive wood is an ideal material for the furniture industry, olive wood products are durable and aesthetically beautiful. The only negative point is the susceptibility to parasites. But if you take proper care of the products, this is not a problem.

Olive wood products have a unique smell, it is not unpleasant, slightly sweet and can last for many more years of olive wood products. In appearance it has some resemblance to marble, this wood gives a yellow-brown core and original stains on a yellow-white canvas.

Application of olive wood

The olive tree, as wood, is often used in the furniture industry. The pattern of wood has a unique character, namely marbling. Most often, veneer is made from olive wood, which then processes the surface of furniture products, giving them an expensive and beautiful appearance. Olive veneer is used to process cabinets, tables, armchairs, chests of drawers, beds and other pieces of furniture. Such furniture is exclusive, has a high cost.

Olive wood is also used for finishing parquet, panel finishing, turning products, artistic products in decorations, small decorative products - dishes, caskets, etc. The material is popular, as it combines the durability of oak and a delicate appearance, and larch resistance to corrosion.

Olive wood: physical and mechanical properties

Oliva belongs to the sound breeds. The core is brown-yellow, with dark brown veins, strokes, stains, which makes it look like marble; sapwood is light yellow, sometimes with greenish stripes. Over time, olive wood becomes reddish.

Such a characteristic of wood as the presence of a large amount of oils makes it not very convenient for processing (see the article “Wood bleaching and deresining”). In addition, olive wood fibers are uneven - they are tangled and wavy, which creates additional difficulties in processing.

Olive wood is dense (880-940 kg / cubic meter), hard, wear-resistant, strong and heavy, the texture is even, fine.

Olive wood: processing

Olive wood is good in carpentry.  Despite the fact that its fibers form a strong "wrong" hitch, it lends itself easily to carpentry. You can achieve a perfectly smooth and even surface.

The properties of olive wood to accept paints, varnishes, mordants well do not apply to water-based products: such  adhesives,  varnishes  and primers can leave stains. Before treating olive wood with polyurethane varnishes, it is necessary to prime the surface to exclude the possibility of ignition.

The use of olive wood should be carried out taking into account its "love" for cracking. Therefore, holes should be drilled in this material before driving nails or screws.

The drying of olive wood deserves special attention   . This process must be carried out under mild conditions, otherwise the olive wood will simply crack and the lumber will turn into marriage. Therefore, only slow drying. Air drying will also work. For 2-3 months, such wood can be dried in piles. If olive wood is properly dried, products made from it will practically not be subject to drying out.

Olive wood (olives): application

As already noted, the use of olive wood is due to its elegant marble texture. Basically we can see this material in the form of veneer.  Chests of drawers, cabinets, tables, armchairs, beds and any other furniture are veneered with olive veneer .

Given the hardness of olive wood, this is an excellent material for parquet or interior decoration. And if we also take into account its high cost, it is better to get by with olive-like parquet or using some elements in artistic  parquet . Wood furniture can be called exclusive, and not everyone can afford it.

Olive wood  is used in marquetry, intarsia, in the manufacture of handicrafts and decor items. And from it you can get elegant and durable kitchen utensils: cutting boards, shovels, spoons.
