In comparison between steel plates, hot rolled low carbon steel plate ASTM A36 steel plates are generally slightly harder than cold rail steel plates and have lower elongation. In cold-rolled steel sheets, the higher the grade, the softer the steel, the lower the yield point, and the higher the total elongation.
Steel low carbon steel plate ASTM A36 exports fell sharply year on year. According to the data of the General Administration of customs, 7.811 million tons of steel were exported from January to February, a year-on-year decrease of 27.0%; 2.041 million tons of imported steel, a year-on-year increase of 2.1%. Steel prices continue to fall. According to the monitoring of China Iron and Steel Industry Association, China's steel low carbon steel plate ASTM A36 composite price index at the end of January was 105.48 points, down 0.58% month on month; at the end of February, the index continued to decline to 100.39 points, down 4.83% month on month.
A514 Gr Q plate is a high strength weldable quenched and tempered steel plate according to ASTM standard. low carbon steel plate ASTM A36, A514 Gr Q plate is mainly used in places requiring high tensile strength and high yield. A514 Gr Q or A514 Gr Q modified are generally used for lifting gear of engineering vehicle and rack of offshore platform. It varies with thickness. Its hardness is 235-290, yield is more than 630MPa, and tensile strength is more than 700MPa.
