Dec 12,2019·They are not much different in chemical composition.It is worth noting that the Al of Q345C,D and E increased by 0.015,harmful elements P and S decreased successively,and the test temperature of low-temperature impact work was low and the price was higher.Q345 series steel has good mechanical properties,good plasticity and sp.info Experimental Study on Mechanical Properties of Q345 Steel Therefore, this paper studies the mechanical properties of Q345 steel after high temperature cooling. chemical composition and cooling mode of steel all have obvious differences in the mechanical properties after high temperature. Therefore, the tensile test of Q345 steel naturally cooled at room temperature (20˚C, 250˚C, 500˚C and 750 sp.info The difference between Q345 and 16Mn_Cangzhou Beite q345 steel is the old brand 14mnnb, 12mnv, 16mnre, 16mn, 18nb, and other alternative steel, instead of just a 16mn steel. In the chemical composition, 16mn and q345 are not the same. More importantly, there is a large difference in the size of the grouping of the two steels depending on the yield strength, which will inevitably cause a change sp.info The difference between steel pipe material 16Mn and Q345 Q345 steel is the oldest 14MnNb, 12MnV, 16MnRE, 16Mn, 18Nb, and other steel alternative, rather than just replace a 16Mn steel. In the chemical composition, 16Mn and Q345 are also different. More importantly, the thickness of the two kinds of steel by the yield strength of the thickness of the packet size there is a big difference, which will lead to some thickness of the material allowable
