Since the container vessel steel manufactured to be subjected to different pressures and strength. Usually pressure is 31.4MPa or higher; operating temperature constant at between -20 ℃ -450 ℃, Hefei steel, there are less than - 20 ℃. According to the working conditions and the processing vessel, requiring vessel steel must have good cold bending and welding properties; good ductility and toughness; high-temperature short-time strength and long-term strength properties. In order to enable the vessel to withstand higher pressures, 35 manganese steel, to reduce the weight of the structure itself, vessel steel materials except outside the high-quality carbon steel, 60 # steel, now mostly low-alloy structural steel for the material. Into the pressure vessel plate poor carbon steel and low alloy steel plate, multilayer low alloy steel plates for pressure vessels and the like. "It should be said that the steel industry restructuring and revitalization planning rules from more long-term considerations, similar to a steel industry policy revision. This policy is difficult to change the current sharp decline in steel demand situation, which in the short term to promote the steel industry is not significantly, q550 steel, but long term, this plan should promote the restructuring of the industry and enhance the competitiveness of a certain role. "well-known steel industry analyst," My iron and steel "has sections analyst Sheng said. Known as the iron and steel industry, it said food plays an important role in national economy. After years of development, the Chinese steel big country already is, but the big but not strong. Since 1996, China's steel production has been 10 consecutive years ranked first in the world. At the same time, Chinese steel production is still emphasis on high energy consumption, low value-added products, some of the high value-added steel is still dependent on imports. 2008 China's total exports of 59.23 million tons of steel, total exports amounted to $ 63.4 billion; total steel imports 15.43 million tons, total imports amounted to 23.4 billion US dollars, the average price of steel imports than exports of steel higher than 40%.
