Q460 alloy steel plate with heavy thickness – Huaxin

product description

Q460 steel, most people may not understand. The “Bird’s Nest” structure design is unique and novel, and the Q460 for building its steel structure has many unique features: Q460 is a low-alloy high-strength steel that will plastically deform when the strength reaches 460 MPa. This strength is larger than that of ordinary steel, so production is very difficult. This is the first time that the Q460 specification steel has been used in the construction of the country. The thickness of the steel plate used this time is 110 mm, which is unique in the past. In the national standard, the maximum thickness of the Q460 is only 100 mm. Previously this steel was generally imported from Luxembourg, South Korea, and Japan. In order to provide the “Bird’s Nest” with the “fit” Q460, since September 2004, the researchers of Henan Wuyang Special Steel Factory have started scientific research for more than half a year, and the three trials have finally succeeded. Today, Q460 steel for the “Bird’s Nest” has begun mass production. In 2008, 400 tons of self-innovated, domestically produced Q460 steel with intellectual property rights will support the iron ore reinforcement of the “Bird’s Nest”.
Q460 is a low alloy high strength steel.
