Welcome to BBN High Strength Steels Factory

S460QL equivalent rolled bar high yield strength

S460QL equivalent, Q890D steel plate is quenched and tempered steel for high-strength structure, the implementation standard: GB/T 16270. In the Q890D steel grade, "Q" means yield, "890" means yield value, and "D" means grade level. The equivalent material of Q890D is EN S890Q steel. The size, shape, weight and allowable deviation of Q890D steel plate shall meet the requirements of GB/T709. Q890D steel plate delivery status (heat treatment): quenching and tempering.

Steel S460QL equivalent 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 S460QL equivalent 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.

The annual sales volume of steel product is over 300,000 tons, and the sales volume has increased year by year. The business scope covers the Southeast Asia, Eastern Europe, Middle East, Africa, North America, and South America. Client services are mainly in the petrochemical, wind power, shipbuilding, steel structure, machinery manufacturing, and construction industries. Throughout the process, we provide customers with professional personal steel customization services and one-stop solutions, professionally set a variety of futures, fast delivery, and excellent prices.

Tempering includes high temperature tempering, medium temperature tempering and low temperature tempering. Tempering means to reheat the S460QL equivalent quenched steel to a certain temperature and then cool it in a certain way. Tempering can reduce or eliminate the internal stress produced by quenching, reduce the hardness and strength, and improve the ductility or toughness of steel. After S460QL equivalent quenching, the workpiece should be tempered in time, and the required mechanical properties can be obtained through the combination of quenching and tempering.
