Q345D low alloy steel plates sold to Vietnam for making machine parts

Our regular vietnam customer ordered us 187tons low alloy steel plates Q345D for making their machines.Due to demand of smaller sizes,so we also do cutting services to this customer in our processing plant.Finally loaded into 8*20GP containers shipped to Haiphong port Vietnam.


Q345D is one steel grade is chinese steel standard GB/T1591.Q345D steel plates have to be done low temperature impacting test under -20 Deg.C.
