This study compared various casting processes and soaking times on the microstructural and mechanical properties of AISI 420 stainless steel. The main discussions on microstructure included: grain size, carbide precipitation and failure analysis. The mechanical properties of hardness, impact and tensile tests were investigated, and elongation and reduction area inspections were performed. In addition, the effects on the mechanical properties of AISI 420 casting steel for different microstructures were also studied.

In the research, the ingot of AISI 420 stainless steel used the granshot which was obtained from Sweden’s Uddeholm Company. The casts were produced by a high-frequency reaction melting furnace at an atmosphere condition. We usually added 7 kg of 420 granshot to the furnace and increased the melting temperature to 1700°C. The soaking time was kept at 1, 10 and 30 min. Meanwhile, the molten casting was formed into the different metal and epoxy resin patterns, respectively. When the castings had solidified, the specimens were cut and removed from the flow direction of the castings after the annealing process. Finally, the quenching and low-temperature tempering treatments were performed in order to investigate the various casting processes and soaking times on the microstructural and mechanical properties of AISI 420 stainless steel.

The experimental results showed that AISI 420 stainless steel casting required a higher melting temperature (1700°C) to provide the driving force of solidification. Increasing the soaking time of the original 420 casting resulted in a higher dendrite rate. Furthermore, the optimal impact toughness of the 420 casting was obtained by the longer soaking time (30 min) of the epoxy resin patterns after heat treatment. The average value of impact energy of 7.63 J increased to 14.3 J. Conversely, the fast cooling rate resulted in poor toughness. The lowest impact energy of the 420 casting was obtained by the longer soaking time (30 min) of the metal pattern after heat treatment. The impact energy of 5.77 J was decreased to 2.93 J. This showed that increasing the soaking time of the metal pattern did not enhance the toughness of AISI 420 stainless steel.
