nm500 steel sheet price 500 tons exported to Hongkong
High strength steel is mainly used in offshore engineering, lifting equipment, construction machinery, container storage tank and other important steel structures with harsh working conditions, hoping to reduce weight. The application of NM500 steel sheet price, high strength steel can not only reduce material cost, transportation cost and production cost, but also save welding material consumption, welding work hour; reduce post welding stress, preheating temperature and post weld heat treatment requirements.
In the welding process, effectively preventing the stress and deformation of the component during the welding process is the key to ensuring the welding quality of the wear-resistant steel plate. In the welding process, after spot welding each part according to the position of the drawing, ensure that the size is consistent with the drawing. The welding method of symmetrical multi-layer multi-pass welding is adopted to ensure the appropriate welding process parameters, which can effectively prevent the welding deformation of the NM500 steel sheet price, wear-resistant steel plate.
Oxygen is a harmful element in NM500 steel sheet price steel. With the increase of oxygen content, the strength of NM500 steel sheet price steel increased, but the plasticity, especially the toughness, decreased significantly, and the weldability became worse. The presence of oxygen causes hot brittleness of NM500 steel sheet price steel.
According to the data of the General Administration of Customs, in April 2020, China exported 6.311 million tons of NM500 steel sheet price and so on steel, down 2.6% from March, down 0.3% year on year; from January to April, China exported 20.601 million tons of steel, down 11.7% year on year. In April, China imported 1.044 million tons of steel, down 11.70% from March; from January to April, China imported 4.184 million tons of steel, up 7.4% year on year.
