How to repair corrosion pits on LR grade B multipurpose cargo vessel steel

In today's LR grade B multipurpose cargo vessel steel steel market, most of the varieties are in excess of demand, especially after China's accession to the WTO, steel enterprises are facing increasingly fierce market competition. In order to make enterprises win a good survival and development space, operators must make effective use of LR grade B multipurpose cargo vessel steel market information resources to improve the scientificity of business decision-making and enhance the enterprises' domestic competitiveness Competitiveness in the external market.

S960QL grade is a European standard special alloy structural steel, which belongs to quenched and tempered high yield strength structural steel. S indicates structural steel, 960 is a yield value, in MPa, Q indicates delivery conditions, and L indicates that the impact energy is specified when the temperature is not less than -50℃ The smaller value of. S960QL steel plate is a material in the European standard EN 10025-6.

The yield strength of Q690D steel plate is 690 Mpa and the impact temperature is - 20℃. LR grade B multipurpose cargo vessel steel, Q690D steel plate has high strength, good plasticity and toughness, good weldability and good cold and hot performance. Q690D steel plate is mainly used to manufacture various large engineering structural components and construction machinery. Because of its high strength and good toughness, Q690D steel plate can reduce the self weight of components and meet the requirements of large-scale and lightweight engineering components and equipment under the condition of ensuring strength, stiffness and reliability.

After adding trace elements such as phosphorus, copper, chromium, and nickel to Q355NH steel, a dense and highly adherent protective film is formed on the surface of the weathering steel, which prevents rust from spreading and developing, and protects the substrate under the rust layer to slow its corrosion . An amorphous spinel oxide layer of about 50 μm to 100 μm thick formed between the rust layer and the substrate is dense and has good adhesion to the base metal, which greatly improves the atmospheric corrosion resistance of the steel material, LR grade B multipurpose cargo vessel steel.
