Laser cutting S690Q steel plate

Normalizing is a special case of annealing, the effect is similar to annealing, but the microstructure obtained by normalizing is finer. For low or medium carbon steel, normalizing can improve hardness and machinability. For S690Q steel plate medium carbon steel and low alloy steel, normalizing can refine grain and uniform structure and reduce hardness. For high carbon steel and high alloy steel, normalizing can eliminate the network carbide produced by forging and improve the homogeneity of the preparation heat treatment structure.

Steel plates for high-rise buildings have the properties of easy welding, earthquake resistance, and low-temperature impact resistance, and are mainly used in large-scale projects such as high-rise buildings, super-tall buildings, large-span stadiums, airports, exhibition centers, and steel structure workshops. Compared with ordinary Q235B / Q345B steel plates, these plates S690Q steel plate for high-rise buildings have upper limits on yield strength and improved tensile strength, and have requirements for carbon equivalent and yield ratio indexes.
