The effect of nitrogen on steel performance is similar to that of carbon and phosphorus. With the increase of A709 Gr 50 carbon steel plate nitrogen content, the strength of steel can be improved, plasticity especially toughness can be significantly reduced, weldability becomes worse, and cold brittleness is intensified. Nitrogen with aluminum, niobium, vanadium and other elements can reduce its adverse effects, improve the performance of A709 Gr 50 carbon steel plate steel, can be used as an alloying element of low alloy steel.
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 A709 Gr 50 carbon steel plate, 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.
Advanced typical figures and typical deeds are the embodiment and symbol of A709 Gr 50 carbon steel plate enterprise spirit, outstanding ideas and vivid images, with strong demonstration, radiation and transmission effect. Without distinctive typical characters, there is no unique enterprise culture. In carrying out the construction of enterprise culture, the advanced enterprise culture should be typified. Vigorously excavate, discover, cultivate and summarize the company's A709 Gr 50 carbon steel plate advanced models.
