| Abstract: | 316L stainless steel by injection molding using coarser powder with particle size of 30um was studied. The effect of injection parameters to the quality of green was studied by orthogonal arrays design and statistical analysis method according to the density and strength of the green part. The right debinding and sintering processes were got. The sintered part is provided with the ideal mechanical property, tensile strength is 630MPa, yield strength is 280MPa, elongation is 52%, hardness is 69.5HRB, corrosion resisting property was evaluated. |
