The difference between Q345 and Q235 Yaang

Sep 08, 2016· Q345 is a steel material. It is a low alloy steel (C <0.2%), widely used in bridges, vehicles, ships, buildings, pressure vessels. Q represents the yield of this material, behind the 345, the yield refers to the value of this material, approximately 345. And will increase the thickness of the material and its yield value decreases.Influence of artificial cooling methods on post fire After exposure to the temperature in excess of 500 °C, the strength and the ductility of these steels cooled by water exhibit significant changes. It is worth noting that the variation in residual yield strength and ultimate strength of Q345 steel, reported in Refs.Material properties of Q345 (16Mn) steel under loading and The yield strength of Q345 steel was measured by Qu [33]. To compare with the model proposed by Li et al. [28], the results obtained by Li's model are also added to the comparisons.
