Effect of laser welding technology on weld microstructure of hardox 450 steel wear resistance
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 Hardox 450 steel wear resistance 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.

Weathering steel is mainly used in railway, vehicles, bridges, towers and other steel structures exposed to the atmosphere for a long time. Hardox 450 steel wear resistance. Weathering steel is used to make structural parts such as containers, railway vehicles, oil derricks, seaport construction, oil production platform and containers containing hydrogen sulfide corrosion medium in chemical petroleum equipment. Weathering steel has the characteristics of rust resistance, corrosion resistance, life extension, thinning and consumption reduction, labor saving and energy saving, which benefits the weathering steel component manufacturers and users.
API 5L steel is pipeline steel mainly for use in oil and gas industry. API 5L steel has PSL1 and PSL2 levels. For same API 5L steel grade, the carbon content for PSL1 is higher than PSL2. Meanwhile, the API 5L PSL2 steel has more strict requirement for P, S content than API 5L PSL1 steel, Hardox 450 steel wear resistance. Therefore, API 5L PSL2 steel strength is higher than API 5L PSL1 steel strength. For example, API 5L X42 PSL2 yield strength is 317-524 MPa, tensile strength is 434-758 MPa. While API 5L X42 PSL1 yield strength is 290 MPa min. , tensile strength is 414 MPa min.
BBN had provided Hardox 450 steel wear resistance Hardox plates for more than 15 years for widely applied in coal mining machinery, cement equipment, road construction machinery, engineering machinery, dump trucks, metallurgical area and port fields. In 2016,we brought our customer to visit our Hardox 450 steel wear resistance NM400 steel plate producing line and our Shanghai warehouse for 30000 tons plate and structure. As a result, Our client purchased 500 tons NM 400 as first order, which is shipped by 3 times. In future, BBN will always guarantee that all the delivery condition for Hardox plate provided will be with quenching and tempering, which is the best delivery type according GBT 24186 standard.
