In 2010, the 87th session of the International Maritime Organization (IMO) Maritime Committee passed the "Performance Standards for Alternative Anticorrosion Measures for Crude Oil Cargo Tanks". It is mandatory that the cargo tanks of large oil tankers above 5,000 dwt need to be protected or used The construction of corrosion-resistant steel promotes the rapid development of the research and application of corrosion-resistant steel for oil tankers in China. At present, the performance of domestic corrosion-resistant steel has reached the world's leading level and can meet the requirements of large-scale applications.
Strip steel is coiled and curved steel plate, which is different from common steel pipes and steel plates. Strip steel has obvious characteristics. First, it is thin and easy to curl, which is convenient for logistics and transportation. Second, the surface quality of ASTM A514 quenched and tempered steel, strip steel is good, the luster is bright and it has good flexibility. Third, the strip steel is easy to process. When you need to use it, you only need to straighten the bent part and you can directly process it. Fourth, the precision is high, and the strip steel can be made of plain carbon steel, carbon structure steel, spring steel, tool steel, stainless steel, etc.
