A572 Gr 65 carbon steel plate sheet non-alloy quality structural steel

Common medium thick and heavy steel plates are widely used for manufacturing various containers, furnace shells, furnace plates, bridges and automobile static steel plates, low steel alloy steel plates, bridge steel plates, general steel plates, boiler steel plates, pressure vessel steel plates, pattern steel plates, automobile girder steel plates, tractor parts and welding components. A572 Gr 65 carbon steel plate sheet, bridge steel plates are used for large railway bridges. They are required to bear dynamic load, impact, vibration, corrosion resistance, etc.

Common specifications for cold-rolled plates: thickness 0.2-4mm, width 600-2000mm, length 1000-6000mm.Commonly used grades: Q19-Q23, Q19F-Q23F, Q29(B)-Q345 A(B); SPCC, SPCD, SPCE, DC01-06.Because rolling at room temperature does not produce iron scale, the cold-rolled sheet has good surface quality and high dimensional accuracy. Coupled with annealing treatment, its mechanical and technological properties are better than hot-rolled thin steel sheets A572 Gr 65 carbon steel plate sheet. In many fields, especially In the field of home appliance manufacturing, it has gradually replaced hot-rolled steel sheets."

A small amount of Nb is sufficient to obtain excellent comprehensive properties of A572 Gr 65 carbon steel plate sheet etc. steel material, because at low Nb concentration, the yield strength of steel material increases faster and is proportional to the concentration, but when the Nb content is greater than 0.03%, the strengthening effect begins to decrease. Studies have shown that when the Nb content is greater than 0.06%, excess Nb will no longer strengthen the steel material.
