A572 grade 42 carbon steel plate sheet tensile test

The selection principle of steel plate for high-rise building is: it can not only make the structure safe and reliable, but also can save steel and reduce the cost. Different use conditions should have different quality requirements. In terms of the mechanical properties of steel such as A572 grade 42 carbon steel plate sheet, yield point, tensile strength, elongation, cold bending property, impact toughness etc. are the indicators to measure the quality of steel. In the design of steel structure, the appropriate steel should be selected according to the characteristics of the structure. The selection of steel is not only an economic problem, but also related to the safety and service life of the structure.

As to the Chemical composition, the different content is a main on carbon content, while the carbon content of A572 grade 42 carbon steel plate sheet, A283Gr. D is no more than 0.27% and it is higher than Grade C (≤0.24%) ; as to the mechanical property, the differences are tensile strength and yield strength, while the tensile strength of ASTM A283 Gr.D is 415-550MPa (60-80 ksi) and yield strength of ASTM A283 Grade D is 230MPa (33 ksi).

In the development process of more than 20 years, the company keeps pace with the times, keeps innovating its ideas, constantly adjusting its steel product A572 grade 42 carbon steel plate sheet structure, constantly strengthening its comprehensive competitiveness, constantly improving its management level, and more importantly, forming its corporate culture of elements and personality. The company always strives to build itself a comprehensive competitive steel A572 grade 42 carbon steel plate sheet supplier in the world.

Temperature has a great influence on the strength of the material, A572 grade 42 carbon steel plate sheet. When the temperature exceeds a certain value, the strength limit of the steel will be reduced. The higher the temperature, the lower the strength. In addition, the longer the steel is used at high temperature, the lower the strength. Therefore, if the steel works at high temperature for a long time, the instantaneous strength of the steel can not be used as its performance index, nor can the room temperature performance replace the high temperature performance.
