Quenching and tempering steel, also known as hardening and tempering steel, is a kind of medium-carbon steel, which is quenched and tempered to achieve the purpose of strengthening and toughening. Steel quenching and tempering process has the following steps: normalizing, quenching and tempering.
Normalizing is to heat the steel to a higher temperature, reduce its internal stress, and increase its hardness and strength. After the equipment cooling process, Quenching is to heat the steel to a higher temperature, quickly cooling it through the quenching cooling medium and the selection of quenching cooling media. According to the different cooling mediums, the quenching cooling process can be divided into quenching, quenching and oil quenching. The final step of quenching and tempering is tempering. After the quenching and tempering process, the steel needs to be tempered. Through the tempering process, the structure of the steel can be changed due to the different tempering temperature and tempering time, so that the mechanical properties of the steel can be improved.
Quenching and tempering steel is widely used in the manufacture of gears, shafts, CNC lathe tools, tools, tools and other parts. Quenching and tempering steel is compared with other steels, showing the best overall performance, it has excellent wear resistance, fatigue strength and impact toughness. Therefore, it is often used to make parts that are subjected to large amounts of fatigue and wear, such as small gears, shafts and other machinery parts.
Quenched and tempered low-carbon steel is a kind of medium-carbon steel, which shows the best overall performance, the tensile strength is higher than yield point strength, has medium hardness and high toughness, and is expected to bear greater impacts. Has excellent wear resistance and fatigue strength, so it is often used to make parts that are subject to large amounts of fatigue and wear, such as small gears, shafts and other machinery parts.
High-carbon quenching and tempering steel is another type of steel quenching and tempering. It has the characteristics of high strength, good wear resistance and high hardness. It is suitable for making parts that need to be subjected to high wear, such as large gears, shafts and other machinery parts.
Quenching and tempering steel has many excellent features and excellent characteristics, so it is widely used in the manufacture of gears, shafts, tools, tools and other parts. Quenching and tempering steel plays an important role in the development of industry, and its wide application makes it an important material in the modern industry. Quenching and tempering steel can also be used to make parts that are subject to high fatigue and wear, such as small gears, shafts and other machinery parts. In addition, quenching and tempering steel is also widely used in the construction of bridges and buildings. Its excellent strength and ductility make it an ideal material for making heavy components in bridges and buildings.
