S690QL elastic modulus as rolled, killed

GB / T1591 Q345D steel is a commonly used low alloy plate in China. It is equivalent to grade S355J2 in Germany and ASTM A529MGr50 in the United States, with slightly different chemical composition and the same mechanical properties. Under normal delivery conditions, S690QL elastic modulus, Q345D steel equivalent to S355J2G3 in European standard, and even almost the same performance as the S355J2G4. They can be used interchangeably.

Compared with the traditional seamless steel pipe, alloy seamless pipe has better performance in all aspects. Because of the addition of various metal elements in the manufacturing, the overall strength of the alloy seamless pipe is larger, stronger and durable, and the service performance and service life of the S690QL elastic modulus, alloy seamless pipe are improved. The alloy seamless pipe is the best choice especially for special environment and high pressure requirements. Because of its high material properties, alloy seamless pipe has good corrosion resistance. It is not easy to be corroded in some special environment, which reduces the cost of the project and has a longer service life.

Steel S690QL elastic modulus 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 S690QL elastic modulus 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.

Steel prices in Europe are under downward pressure due to temporary shutdowns by auto makers in most of Europe and the disruption of trade flows due to reduced trade activity in the construction and other steel industries. Despite the import safeguard measures adopted in Europe, some key steel prices have reached a three-year low in 2019. At that time, the European market was oversupplied. Despite the import safeguard plan, the imports to the European Union remained at a historical high, and now the S690QL elastic modulus and so on steel price is even close to the level of 2009.
