Q345 is a kind of steel material. It is a carbon alloy steel (C < 0.2%), with good comprehensive properties, low temperature properties, cold stamping properties, welding properties and machinability. It is widely used in bridges, vehicles, ships, buildings, pressure vessels, etc. Q represents the yield of this material, and 345 in the back refers to the yield value of this material, which is about 345 MPa. The yield value decreases with the increase of material thickness.
It is composed of Q + number + quality grade symbol + deoxidation method symbol. Its steel grade is prefixed with "Q" to represent the yield point of the steel, and the subsequent number represents the yield point value in MPa. For example, Q235 represents the carbon structural steel I with a yield point (REL) of 235 MPa. When the brick Carver requires the steel plate to have the performance in the thickness direction, the symbol representing the performance level in the thickness direction (z direction) shall be added after the grade, for example, Q345BZ15.
If necessary, the symbol indicating the quality grade and deoxidation method can be marked after the steel grade. The quality grade symbols are a, B, C, D and E. Symbols of deoxidation method: F for rimmed steel; B for semi killed steel; Z for killed steel; TZ for special killed steel, which can be omitted, i.e. both Z and TZ can be omitted. For example, q235-af stands for class a rimmed steel.
Carbon steel for special purposes, such as bridge steel, marine steel, etc., basically adopts the expression of , but the letter indicating the purpose is added at the end of steel grade.
