Yield point of Carbon Structural Steel
Carbon structural steel is a kind of wrought steel with carbon content of 0.12% to 2.1%. In terms of physical properties, carbon structural steel has excellent hardness and strength. According to different elements and internal structure, carbon structural steel can be divided into different grades.
Yield point is an important structural mechanical property in the engineering field. It represents the limit of a metal’s elastic properties and is used to determine the ultimate load in a variety of structural stability calculations. The unit of this quantity is generally expressed in megapascal (MPa), Kg/mm2 or PSI (1MPa=1000 Kg/mm2=145.038PSI).
The yield point of carbon structural steel generally varies between 235MPa and 700MPa under room temperature. The highest of all carbon structural steel is 700MPa, but in order to ensure the quality and ensure that the strength is only reduced by 0.2%, the yield point of carbon structural steel is generally set to 650MPa. In addition, other factors such as the internal structure, additives and heat treatment state of the carbon structural steel should also be considered when considering yield point value.
In addition, the yield point of carbon structural steel is greatly influenced by carbon content. For example, the yield point of low carbon structural steel (with carbon content ≤ 0.2%) is 235MPa, while high carbon structural steel (with carbon content ≥ 0.6%) can reach 390MPa.
When comparing similar grades of carbon structural steels, CNC machining carbon structural steel shows the best yield point performance. In the process of machining, carbon structural steel is heated to a certain temperature and then cooled in water. During this process, CNC machining carbon structural steel can eliminate or reduce internal stress, making it have excellent performance in yield point. Therefore, CNC machining carbon structural steel is often used as a structural material in important engineering fields.
In conclusion, the yield point of carbon structural steel has a great influence on its function and scope of application. Therefore, when selecting carbon structural steel, it is necessary to pay attention to the relevant specifications and make appropriate choices based on its own needs.
