Investigation on Microstructure and Impact Properties of Borated Stainless Steel for High Density Storage Racks

Abstract:

In this paper, microstructure and impact properties of borated stainless steel type 304B6-GradeB were investigated, which was used as raw materials of high-density storage racks in some nuclear power plants. Microscopic examinations reveal that a large amount of particles are heterogeneously distributed on austenitic matrix which displayed different shapes in the rolling and thickness directions, the results of XRD and EDS prove that the secondary particle is (Fe,Cr)₂B and boron is distributed only in the particles while not in the matrix, fracture analysis all indicates that this borated stainless steel type 304B6-GradeB obviously exhibits features of brittle fracture.
