Effect of Different Annealing and Holding Time on the Microstructure and Properties of 304 Austenitic Stainless Steel
In this paper ,the effects of different annealing times on the grain structure ,tensile properties and microhardness of 304 stainless steel were studied ,and the variation of grain size ,tensile strength ,deformation and microhardness value of cross-section of 304 stainless steel under different heat treatment conditions of 800 ℃ annealing temperature and 5～20 min was analyzed by comparing the differences in microstructure and mechanical properties ,and the influence mechanism of dif-ferent holding time on the microstructure and property evolution characteristics of 304 austenitic stainless steel was discussed.
