The company celebrates Hong Kong-Zhuhai-Macao Bridge Opening. In October 23th, 2018, Chinese President Xi Jinping announced the opening of the Hong Kong-Zhuhai-Macao Bridge (HZMB) in Zhuhai, South China’s Guangdong Province. The HZMB is a 55-kilometre (34 mi) bridge–tunnel system consisting of a series of ASTM A709 high strength steel three cable-stayed bridges, an undersea tunnel, and four artificial islands. Hong Kong-Zhuhai-Macao Bridge is the world’s longest sea-crossing bridge connecting Hong Kong, Macao, and Zhuhai—three major cities on the Pearl River Delta.
Boiler steel is different from ASTM A709 high strength steel. Boiler steel is used to make boilers. Boiler steel can be divided into steel for boiler steel pipe, boiler steel plate and boiler steel fasteners. Boiler steel is smelted by open hearth furnace, converter, electric furnace, and some also use the refining process outside the furnace. Boiler steel for steel pipes refers to the steel used for the manufacture of superheaters, reheaters and headers. Their working temperature is higher than other parts, and the environment is also harsher.
2020 October ASTM A709 high strength steel specification: 8*2200*10000, 16*2150*10400, 30*2500*6200, 31.2*2950*9380, 7*2200*8000, 30*2200*10000, 14*2400*9900, 18.5*2700*9570, 21*2100*8810, 14*2070*9060, 12*2200*10000, 14*1950*8000, 36*2200*7700, 7*2200*8000, 14*2070*9060, 10*2200*8000, 20*2500*10000, 14*2400*10000, 30*2000*7400, 6*2800*12000, 21*2100*8810, 32*2200*10000, 16*2150*10250, 27*2500*9000, 20*2100*7000, 21*2100*9100.
