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 A588 grade B high strength steel. In many fields, especially In the field of home appliance manufacturing, it has gradually replaced hot-rolled steel sheets."
The boiler steel plate has small strain aging sensitivity, especially in the corresponding working temperature range, a certain value of aging impact energy must be guaranteed;The boiler steel plate has low notch sensitivity, which can prevent steel from cracking in welding, opening, and local stress concentration areas;The A588 grade B high strength steel, boiler steel plate has good welding performance;The A588 grade B high strength steel, boiler steel plate has a good microstructure, white spots and cracks are not allowed.
The purpose of alloying Q345B steel is to use the interaction of alloy elements with iron and carbon and the effect on iron-carbon phase diagram and the heat treatment of steel to improve the structure and properties of steel. Interaction of alloying elements with iron and carbon: After alloying elements are added to steel, they mainly exist in steel in three forms. That is: forming a solid solution with iron; forming carbides with carbon; and possibly forming intermetallic compounds in high alloy steels, A588 grade B high strength steel.
