The microprocesses of crack initiation and propagation in a B hull structural steel have been investigated by using an scanning electron microscope with a microtensile holder,and the secondary crack propagation at low temperature has also been studied by SEM.

The properties of Q235 carbon steel and grade B ship plate were measured.
