Japan continues to cut A572 Grade 50 steel material production capacity

Shipbuilding steel plate as a kind of specialized steel plate is used for shipbuilding and offshore platforms. BBN steel is able to supply various kinds of marine steel plates, steel sections and steel structures including general strength shipbuilding steel plates, A572 Grade 50 steel material,high strength shipbuilding steel plates and ultra high strength shipbuilding steel plates. The nominal yield strength of the steel plate is in the range of 235MPa to 690MPa. Its actual yield strength is superior to its nominal strength in general.

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 A572 Grade 50 steel material 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.

Phosphorus element (P element) is brought into steel by ore. Generally speaking, phosphorus is also harmful element. Although phosphorus can increase the strength and hardness of A572 Grade 50 steel material etc. steel, it also causes the decrease of plasticity and impact toughness. Especially at low temperature, it makes steel significantly brittle, which is called "cold brittleness". The higher the phosphorus content is, the greater the cold brittleness is. Therefore, the phosphorus content in A572 Grade 50 steel material etc. steel is strictly controlled.

Industry experts point out that employment in the steel industry will almost certainly continue to decline as a consequence of automation, even if production and profits increase. As the conservative think A572 Grade 50 steel material tank AEI points out, “Mr. Trump’s tariffs are trying to revive a world of steel production that no longer exists. He is taxing A572 Grade 50 steel material steel-consuming industries that employ 6.5 million and have the potential to grow more jobs to help a declining industry that employs only 140,000.”
