Nov 27,2019 q345 vs q345b#0183;For example,Q345 represents yield.WhatisQ345B? Q345B is a low alloy high strength structural steel.Q the first letter of the Chinese Pinyin of the word Qu of the yield strength of steel; 345 the value of the yield strength,in MPa; B the quality grade is B,which means that 20 degree impact test is required.The difference between Q345 and Q235 - YaangQ345 is a steel material.It is a low-alloy steel (C q345 vs q345blt;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.Some results are removed in response to a notice of local law requirement.For more information,please see here.
