Carbon Tool Steel
Carbon tool steel or low-harden ability made according to GOST 1435-74. Marking the letter A is used for tool carbon steel of high quality.
There are two types of carbon tool steels:
- Quality tool steel which contains 0.03% sulfur and 0.035% phosphorus
- Stainless tool steel containing 0.03% P and 0.02% sulfur
- The main brands include carbon steel tool U7, U8, U9, U10, U11, U12, and U13.
The extensive use of carbon steel tools is found in the production of various tools that are not exposed in the process of high dynamic loads.
Instrumental Alloy Steel
Instrumental alloy steel or tool steel increased harden- ability according to GOST 5950-2000 is an alloy of iron and carbon, in which the amount of carbon equal to 0.9-1.4%. For doping, tool steels used silicon, tungsten, chromium, manganese and other elements. The main application of alloy tool steel is manufactured of stamping and cutting tools. Among the most common brands of alloy tool steel can be identified, such as 9XC, H12MF, CVH and others.
Die Tool Steel
Die Tool Steel – this alloy tool steel, which is used in the production of tools such as rollers, stamps, dies, punches, etc. In accordance with Die tool steel must be wear resistant, thermally stable and sufficiently strong, protecting against deforming under the action of the metal workpiece. The most common brand of die steel: H12MF, 4H5MFS and H12F1.
Instrumental Hss Tool Steel
High-speed tool steel 19265-73 is widely used in the manufacture of cutting tools, which is characterized by work at high speeds, which leads to the following properties of high-speed steel:
- High wear resistance,
- High strength and
- Red hardness
Main Types and Characteristics
Tool steel primarily based on the name implies is used for the manufacture of tools, car parts and tools that can withstand vibrations and dynamic load different strengths. Tools can be as measuring and cutting.
Tool steels include:
- Carbon tool steel
- Alloy tool steel
Key features of tool steels
Carbon steel is basically used for manufacturing patented wire or ribbon. It is widely used for products that need to be constantly and repeatedly heated during the manufacturing process. Instrumental carbon steel must be made in accordance with GOST 1435-99.
Carbon tool steel is divided into several types for different reasons. Thus, depending on the processing method, tool steels can be divided into two types:
- Steel without heat treatment
- With heat treatment steel
Instrumental alloy steel, depending on the quality of surface finish, can be 3 types:
- Hot-rolled steel
- Forged steel
- Calibrated steel
Having a special surface finish is the last thing you should consider. Instrumental speed steel should be made in accordance with GOST 19265-73. From the title becomes immediately clear that this type of steel made cutting tools. This is possible thanks to the properties of high-speed steel as a sufficiently high heat resistance and hardness, durability, and ability to withstand temperature fluctuations. Its undoubted advantage is the fact that it has excellent weld ability.
