ABSTRACT:
A sintered stainless steel having an overall density of at least 95% of full density and a morphology comprised of regions of sintered austenitic stainless steel and regions of solidified liquid phase. Moreover, a sintered steel which is made by: pressing and sintering pre-alloyed powder consisting essentially of, by weight, up to 0.05% carbon, 22 to 26% chromium, 10 to 24% nickel, 2.7 to 5% molybdenum, 0.1 to 1% boron, up to 2.0% manganese, up to 2.0% silicon, balance iron and residuals.
