SA572 Gr 65 carbon steel plate sheet main useage

With the increase of carbon content in the steel material, the yield point and tensile strength increase, but the plasticity and impact decrease. When the carbon content is more than 0.23%, the welding performance of the steel material becomes worse. Therefore, the carbon content of low alloy structural steel used for welding is generally less than 0.20%. The high carbon content can also reduce the atmospheric corrosion resistance of steel material, and the high carbon steel in the open air is easy to rust; in addition, carbon can increase the cold brittleness and aging sensitivity of SA572 Gr 65 carbon steel plate sheet etc. steel material.

According to the data released by the Japan iron and Steel Union (JISF), the export volume of Japanese steel in the second quarter of 2020 SA572 Gr 65 carbon steel plate sheet is about 4.959 million tons, a year-on-year decrease of 14.2%; the export volume in the first half of 2020 is about 11.07 million tons, with a year-on-year growth of 1.8%. It has been revealed that the year-on-year increase in export volume does not mean that Japan's export SA572 Gr 65 carbon steel plate sheet situation of Pugang is better in the first half of the year, but only because the base number of the same period last year is too low.

On November 25, the price of the SA572 Gr 65 carbon steel plate sheet medium board in the Yinchuan market remained stable temporarily, and the market transactions were average. As of press time, Yinchuan market 16-25mm general medium plate is 4020 yuan/ton; 14-25mm low alloy medium plate is 4170 yuan/ton. The price of plate in Yinchuan market continued to stabilize without much change. However, as the temperature dropped sharply and terminal demand in the local market dropped to a low point, plate merchants in the Yinchuan market had difficulty shipping.

The tensile strength of seamless steel pipe is more than 8-10 times of that of ordinary steel, and its elastic modulus is better than that of steel, with excellent creep resistance, corrosion resistance and seismic resistance; the mechanical performance of seamless steel pipe is excellent, easy to machine, etc.; the seamless steel pipe SA572 Gr 65 carbon steel plate sheet is highly elastic, reused in mechanical equipment, memoryless, deformation free, and antistatic.
