The impacted and tensile-fractured specimen of 316H steel medium plate was analysised by SEM
the result was showed that the morphology of fractured specimen with lower impact energy and yield strength of 316H medium plate was brittle fracture because of σ precipitation phase in the middle of plate
which decreased the plasticity and toughness of steel. The formed link of a phase was found out in process of rolling and heat treatment
and then the cooling rate after rolling
heating rate
holding temperature
holding time in process of heat treatment were adjusted
the ct phase was not precipitated in any position in the plate
the mechanical property of plate in every place of 316H medium plate is qualified.
