Abstract

304 stainless steels with different Al content were warm-rolled and subsequently solution-treated. The microstructure, phase constituent and composition of the alloys were characterized by means of OM, XRD and EPMA. The results show that black ferrite phase with shapes as strips, short rod and some granular-like distribute throughout the white austenite matrix;The majority of Al dissolves in the matrix,while there exist precipitates of AlN and other black-phases. The hardness and corrosion resistance of the steels increase gradually with the increasing rolling temperature, and their break elongation reaches about 47%. The deformation capacity of the steels is greatly improved and the tensile strength of the steel with 1% (mass fraction)Al achieves to 766 MPa. The fracture surfaces exhibit large and small dimples with size of 5~15 μm and ≤5 μm, respectively. The fracture models are similar and belong to ductile fracture. By the same rolling temperature the steel with 1.5% Al has better corrosion resistance performance.

Key words: metallic materials warm-rolled tensile deformation corrosion resistance 304 stainless steels
