NM400 sheet size thickness equivalent

The characteristic of niobium in NM400 sheet size thickness etc. steel material is to increase the recrystallization temperature of austenite, so as to achieve the purpose of refining austenite grains. In general, the amount of niobium added in steel material is less than 0.05%, and the contribution of niobium above 0.05% to strengthening and toughening will no longer be obvious.

NM400 sheet size thickness, 22SiMn2 steel is a kind of high strength manganese resistant steel. It is mainly used to bear the impact, extrusion, material wear and other harsh working conditions. The main form of damage is wear consumption, and part of fracture and deformation. 22SiMn2 steel is made of H08Mn2SiA filler material, and Ar + CO2 gas shielded welding. Through reasonable process selection, the welded joint with strength and toughness meeting the engineering requirements can be obtained.

Flat steel is a kind of steel with rectangular cross-section and blunt edges at the edges and corners. It is usually 12-300 mm wide and 3-60 mm thick. Compared with NM400 sheet size thickness ordinary steel plate, the utilization rate of flat steel is increased by one to five percentage points. Moreover, flat steel can be produced with fixed thickness, width and length according to the user's requirements, which saves the cutting process for users, reduces the consumption of labor and materials, and also reduces the processing loss of raw materials, saving time, labor and material.

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.
