What causes the rust phenomenon of St37-2 carbon steel plate sheet

The characteristic of niobium in St37-2 carbon steel plate sheet 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.

Grades St37-2 carbon steel plate sheet, Q345 (16Mn) and Q390 steel have good comprehensive mechanical properties, good welding performance, cold and hot workability and corrosion resistance. C, D, E grade steel has good low temperature toughness. Mainly used for ships, boilers, pressure vessels, petroleum storage tanks, bridges, power station equipment, lifting and transportation machinery and other higher-load welding structural parts.

Safety is the eternal theme of steel companies and the key to the survival and development of steel companies. BBN steel company must not only improve employees’ safety awareness, change the safety education model, establish and improve safety management systems, but also take talent training and technological innovation as breakthrough points, and build the "Internet + safety management" model as the development direction to strengthen safety Manage and strictly prevent safety accidents.

St37-2 carbon steel plate sheet product plate specification range: Thickness 3-150mm Width 1500-4020mm Length 4000mm-17000mm Heat treatment: annealing, or normalizing and tempering
