ASTM A709 steel material elastic modulus

12Cr2Mo1R steel plate is a kind of Cr-Mo alloy steel, which is a widely used heat-strength steel and hydrogen-resistant steel. As alloy elements such as Cr and Mo are added to low carbon steel, the comprehensive properties of the steel ASTM A709 steel material are greatly improved, such as good high temperature mechanical properties, high temperature oxidation resistance, corrosion resistance, good toughness, process performance and weldability.

The main advantage of weather resistant steel plate is its weathering ability. When exposed to the atmosphere, the weather resistant steel plate will form a anti-corrosion film on the surface, and prevent further corrosion to the steel ASTM A709 steel material. Thus the weather resistant steel plate almost needs no paint treatment, which is the important measure for carbon steel plates to avoid going rust. Therefore, the maintance cost of weather resistant steel plate is low. The weather resistant steel plate is suitable for outside structure and construction use.

Primary processing, steel plate cutting processing cutting method, it is a flame cutting, because it to the accuracy requirement of the cutting size is not very high, the thickness of the ASTM A709 steel material plates in a certain range can be a good cutting quality and cutting effect, and the cut surface can be very smooth, however, it is important to note that in this work, is the need to pay attention to steel plate deformation at high temperature.
