Rapid sintering feedstock for injection molding of stainless steel parts

摘要

A feedstock, for the production of stainless steel injection molded parts, capable of producing high theoretical density using lower than conventional sintering temperatures. In the production of powder metal parts, densities approaching theoretical density are normally achieved by the use of high compaction pressures, high temperature sintering, or a combination of both. By employing a higher chromium content and a lower nickel content than conventional 316L stainless steel, a duplex structure of ferrite and austenite will be produced with superior sintering capability--resulting in higher densification and better mechanical properties at lower sintering temperatures.
