In the present study, effect of sintering temperature and atmosphere on corrosion behavior of 316L stainless steel specimens manufactured by metal injection molding (MIM) process were investigated. Sintering experiments were carried out at 1320°C, 1370°C and 1375°C under various sintering atmospheres, i.e. Ar+H2, Ar, N2+H2 or N2. The corrosion behavior of as-sintered specimens was studied by weight loss immersion test in 5%HCl solution. The results indicated that a better corrosion resistance was accompanied higher density, finer and rounder surface pores. The specimens sintered under Ar+H2 atmosphere at 1370°C had little susceptibility to intergranular corrosion.
