Some foreign customers are often confused about GB Q345 steel. Q345 low alloy high strength steel is the replacement steel of old GB grade 12MnV, 14MnNb, 18Nb, 16MnRE, 16Mn, etc. The chemical element is similar to 16Mn, and Q345 increases the micro-alloy element V, Ti and Nb which refines the grain, greatly improving the toughness and comprehensive mechanical properties of steelsp.info Dynamic mechanical behaviour of Q345 steel at elevated Oct 24, 2014 · It aims to study the Q345 steel’s mechanical properties at elevated temperatures under different strain rates. The experimental results show that, at normal temperature, the dynamic strength of the Q345 steel is markedly higher than that under the quasi-static state. It displays an obvious strain rate strengthening effect.sp.info Thermal Simulation on Mechanical Properties of Steel Q345 We found the strength of steel Q345 cast slab felled down basically; the ductility was decreased below 700°C, in the range of 725°C-900°C and 1275°C-melting point. The plastic modulus was analyzed with the different temperatures and the different strains in detail.
