Khmelnitsky sheet, circle tool steel U8A, HVG, 9XC, 5HNM, R6M5, spring-loaded 65G

This type of steel is used in the manufacture of hand tools (files, chisels, milling cutters, drills, axes, etc.), as well as equipment in which the cutting edge and other working elements do not heat up.
We produce and supply tool steel grades 4Kh5MFS, 5KhNM, 9KhS, U8A, EK-80Sh, KhVG 150, KhVG 200, KhVG 250, KhVG 300.
Wholesale deliveries to legal entities and individuals. The minimum purchase lot is 100 kg. Carbon steel has the letter "U" at the beginning of the name, indicating the corresponding type. The numbers following it indicate the percentage of carbon content.
The letter "A" at the end of the name indicates that this type of steel is of high quality and strength.
Alloy steel is marked first with a number showing tenths of the carbon contained in the alloy.
The letter "P" in the marking indicates the type of high speed steels.
The letters "A", "B", "D", "E" at the beginning of the marking indicate a particularly high strength of the alloy. We produce tool steel in accordance with state standards. The most popular are alloyed, carbon and high-speed tool steels.
Carbon tool steels have high wear resistance, strength and hardness, but when the product is heated (arising from friction), some of their characteristics fall. This determines their main purpose: the production of tools that are not intended for processing parts (materials) at high speeds.
In order to improve the performance of carbon steel, a low-alloy steel with a small inclusion of chromium was created. This category of steels made it possible to reduce defects from damage to the structure and deformations of various kinds, low-alloy steels are insensitive to overheating and are well processed. Alloyed tool steel has even better characteristics - it allows you to harden the product in different temperature environments, which increases the strength and hardness of the product. Among alloyed steels, such grades as 9XC and KhVG are most widely used. The first grade of tool alloy steels has a uniform distribution of inclusions over the metal structure and is recommended for use in the manufacture of thread-cutting tools. The second is used in the manufacture of tools operating in light and medium conditions.
The general characteristic of alloyed tool steels is such that they are significantly superior to carbon and low-alloyed ones in terms of heat resistance (they do not lose strength when overheated).
