Vanadium is a weak deoxidizer. Adding vanadium into RINA DH32 watertight bulkhead steel steel can reduce the adverse effects of carbon and nitrogen, effectively improve the strength, but sometimes also increase the tendency of welding hardening, vanadium is also a commonly used trace alloy element.
Steel is the main raw material for shipbuilding and marine engineering structure construction, accounting for 20% ~ 30% of the construction cost of hull and marine engineering. The steel RINA DH32 watertight bulkhead steel products involved mainly include steel plates and section steel (marine bulb flat steel, H-beam, angle steel, etc.), casting and forging steel and supporting welding materials, etc. Among them, the amount of steel consumed for hull construction accounts for about 60% of the total ship mass, and sheet metal accounts for about 88%.
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 RINA DH32 watertight bulkhead 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.
In February 2019, the European Union stated that the sharp increase in Turkish RINA DH32 watertight bulkhead steel and so on steel imports has seriously threatened steel production enterprises in member states. The EU has set import quotas for 26 steel products and imposed a 25% tariff on steel products imported in the future for a period of three years. The Turkish Trade Ministry said on Friday that Turkey had initiated a lawsuit against the EU on steel import tariffs with the World Trade Organization (WTO).
