Abstract
ABSTRACT The microstructure and mechanical properties of 17-4 stainless steel produced by Binder Jetting (BJT) and heat treated according to the standard conditions for the 17-4 PH steel (H900 and H1100) were investigated. The sintered relative density is 97.8% with a slightly anisotropic shrinkage. Tensile strength and elongation are above the minimum required for the wrought steel and comparable to those of the same material manufactured by Metal Injection Molding. They are also better than those reported in the literature for the 17-4 PH stainless steel manufactured by BJT. Tensile elongation at fracture is anisotropic, highlighting a significant dependence of the non-uniform plastic deformation on the direction.
