Characteristics of steel 40х13, scope and reviews

Any steel has certain properties, specific only to a particular brand. And metallurgists are trying to make every effort to obtain the highest and highest quality characteristics of the material. But, since to get the perfect structure of steel is not quite real, it all comes down to selecting the best opportunities for certain purposes. After all, everyone knows, which is easier to sharpen than mild steel, than that, which is made of stiffer. And solid steel, vice versa, differs in high resistance to mechanical influences.

With a complex chemical composition, the production process of steel production slows down, due to which the cost of the finished product increases.

The quality of the knife may not always depend on the specific grade of steel. High-quality heat treatment of the product plays an important role here. The most popular steel for the manufacture of knives is steel 40x13. It has all the necessary properties and characteristics.

What are the characteristics of steel 40x13

Steel grade 40x13 has the following characteristics:

1. Has powerful heat resistance.
2. Resistance to various corrosion.
3. It is considered a completely rusty material.

Steel acquires its anti-corrosion properties due to a complex technological process, which provides special hardening. As a result of this procedure there is a complete dissolution of carbide, which provides corrosion protection of the material. One of the reasons for the decrease in corrosion resistance is the reduced content of chromium in the carbide or lowering the melting point of steel to 600 degrees. But, if the technological process is provided correctly, then this should not happen.

Melting steel in special open furnaces. Induction furnaces can also be used for this purpose. The process of melting steel is carried out at a temperature of 850 to 1100 degrees, which ensures its complete deformation. To avoid cracks, technological procedure provides special modes of heating and cooling, which are held alternately.

Components after hardening

After the steel has passed the hardening procedure, its components are the following elements:

• carbide particles;
• martensito;
• residual austenite.

After reaching the temperature limit 1050 degrees and above, there is a decrease in the hardness of the material. That says, about increasing the amount of austenite in the steel. When the melting point decreases to 450-550 degrees there is a secondary hardness of the material, which occurs as a result of the separation of fine carbide from steel.

Scope of steel 40x13

Steel grade 40x13 is widely used for the manufacture of inexpensive domestic kitchen knives. Products made of this steel are perfect for household use, as they are not covered with rust under any circumstances, easy to sharpen and easy to use, and in care. With a knife with this steel you can easily cut all kinds of gastronomic products, meat, fish, vegetables and fruits. This blade is not only quite sharp, but also completely safe for food use.

in addition, 40x13 steel is used for the production of medical scalpels and other instruments. It is used to make measuring devices, springs, bearings, compressor elements and other items, which can be used in the household.

The only disadvantage of such steel products is this factor, as instability to aggressive environments and high temperatures. Therefore, this type of steel is prohibited for use in quarrels.

What are the reviews of 40x13 steel products?

40x13 steel products are in great demand among a wide range of consumers. Therefore, the production of this brand of steel occupies an important place in metallurgy. Many note, that knives made of this material are very durable due to their hardness. The blades sharpen well and remain sharp for a long time. In addition, the steel is not subject to corrosion, which further increases its market demand. Moreover, products from it have reasonable cost in comparison with other its analogues.

Divers especially love steel 40x13, fishermen, divers and just a hostess. After all, knives, produced from this steel, really practical for use in various fields. Souvenir swords are also successfully made from it.

It should be noted, that steel products do not require any special care, in addition to sharpening. But, but with 40x13 steel requires careful handling, since the blade blades are very flexible. Example, you cannot use such a knife to work with hard surfaces.

Manicure tools are especially popular, made of such material, as steel 40x13. Due to its hardness, tweezers handle the cuticle well. At the same time it is not necessary to sharpen the tool often. And its constant use does not lead to deformation of the product.

Medical staff are particularly pleased with the quality of the blades, in particular, surgeons. After all, scalpels are made mainly of steel 40x13. It even acquired a new name - medical steel.

Remember when buying 40x13 steel products, things need to be neat. Knife blades do not like storage in damp and very humid conditions. Small rust spots may appear on them, which after sharpening, of course, will disappear. But, it is better not to make such mistakes.

I have been using a 40x13 steel kitchen knife for several years now. And I want to say, that the knife from such material is strong enough and convenient in application. It sharpens well and easily. It cuts even hard meat and fish perfectly. Its durability is impressive. Do not sharpen the blade at all with constant operation.

I already work as a manicurist 10 years. In the work it was necessary to use various cutting tools for giving to nails of the necessary form and tidy appearance.. I was especially pleased with the cuticle tweezers, made of steel 40x13. The material is quite strong, remains acute for a long time, when sharpening is not deformed.

The market offered to buy a bicycle bearing made of 40x13 steel. I was very pleased. It turned out to be quite strong and high quality. Highly recommend!
