The effect of titanium content on mechanical properties of 14~20 mm hot rolled plate of Q345A steel (0.08~0. 10C
1.19~1.46Mn
0.017~0.029Nb
0.02~0.08Ti) has been studied. Results showed that as Ti=0.02%
the strength of steel plate was not obvious change
as Ti content was0.02~0.04%
with increasing Ti content the strength of steel plate increased
and as Ti≥0.04%
with increasing Ti content the strength of steel plate decreased. With controlling Ti content within0.02%~0.04% in Nb-Ti microalloying Q345A steel for heavy truck plate
the optimum combined strength and plasticity shall be got.
