Q255 and Q275 mass fraction of carbon steel is slightly high, high strength, good plasticity and toughness, can be welded steel, steel rolling, usually forming and plate structure and simple manufacturing machinery, connecting rod, gear coupling, pins and other parts. Plain carbon steel high carbon steel is basically contains alloy elements, the carbon content in the range of 0.65% ~ 1.35%, the production of low cost, easy to obtain raw materials, good machinability, after treatment can obtain high hardness and high wear resistance, so the steel is widely used to manufacture various. Cutting tool, mold, measuring tools.But the red hardness difference of this kind of steel, that is, when the working temperature is greater than 250 degrees, the hardness and wear resistance of steel will decline rapidly, and lose their ability to work. In addition, if carbon tools steel is made into larger parts, it is difficult to harden, and deformation and crack are easy to occur. This kind of steel must ensure both chemical composition and mechanical properties. The number is two digits by the average mass fraction of carbon steel in the 000 fraction (W C * 10000). For example, steel 45 shows the average mass fraction of carbon in steel is 0.45%; 08 steel indicates the average mass fraction of carbon in steel is 0.08%.

- Q:What is the role of boron in special steel alloys?
- Boron plays a crucial role in special steel alloys, particularly in enhancing their mechanical properties and overall performance. One of the primary functions of boron is as a hardenability agent, meaning it improves the hardness and strength of the steel. This is achieved through the formation of boride particles, which act as strengthening agents within the microstructure. Additionally, boron aids in the refinement of the grain structure of steel, resulting in improved toughness and resistance to cracking. It promotes the formation of fine-grained microstructures, which in turn increase the steel's ability to withstand high temperatures, pressure, and wear. Moreover, boron assists in the solidification process of steel, reducing the risk of hot cracking during casting or welding. It lowers the melting point of steel, allowing for better fluidity and improved flowability during manufacturing processes. Furthermore, boron can also enhance the machinability of steel alloys, making them easier to work with and reducing tool wear. Overall, the addition of boron to special steel alloys significantly contributes to their strength, hardness, toughness, and resistance to various forms of degradation. Its role is vital in optimizing the performance and durability of these alloys in demanding applications such as automotive components, aerospace structures, and industrial machinery.
