Q345 is a kind of steel. It is a low alloy steel (C<0.2%) with good comprehensive performance, low-temperature performance, cold stamping performance, welding performance， and machinability. Widely used in bridges, vehicles, ships, construction pressure vessels, etc. Q represents the yield strength of the material. The latter 345 refers to the yield value of this material, which is about 345. Yield value decreases with increasing material thickness. Q345A (GB/T 1591-1994) ω/% Performance and application: Similar to Q235 nomenclature. Q345a, Q345b, Q345c, Q345d, Q345e. This is the classification of grades, representing different shock temperatures! For Q345A, no impact; for room temperature shock 345B; for Q345C, 0-degree shock; for Q345D, -20 degree shock; for Q345E, -40 degree shock. Under different shock temperatures, the shock value is also different. It belongs to the low alloy series in the plate.
* Mild steel strips are malleable, highly ductile, and can be used in automotive body parts, sheet, and wire products. *At the high end of the low carbon content range, plus up to 1.5% manganese, its mechanical properties are suitable for stampings, and forgings. Seamless tubes and boiler plates. *Popular applications for medium carbon steel strips include axles, axles, gears, rails, and railway wheels
