Pressure vessels are defined as containers for the "containment" of internal or external pressure. This definition applies to a very wide range of pressure vessels, some of which have not been considered in the development of the 18MnMoNbR equivalent material rules.
In general, the global manufacturing industry has been seriously impacted by the epidemic, and the foreign epidemic is still in the outbreak period, and its 18MnMoNbR equivalent material demand recovery still has some time. However, the domestic epidemic situation has come to an end. In addition, the state has repeatedly stressed that the development of traditional infrastructure and new infrastructure needs a lot of steel. And now the return to work is getting better. As of March 20, the return rate of key projects is 89.1%, and the return rate of 11000 key projects in China is nearly 90%.
As a common steel plate in the steel market, 18MnMoNbR equivalent material, manganese steel plate has the following characteristics. First, good toughness, stretching and crimping can be done well. Second, the bearing strength of manganese steel plate is good and it can bear a lot of gravity. Third, the 18MnMoNbR equivalent material, manganese steel plate is easy to weld, easy to process finished products, and its price is relatively low. Fourth, manganese steel plate has good corrosion resistance, and long service life. Fifth, the manganese steel plate has good mechanical properties, low temperature performance, good plasticity and weldability.
