MULTI-PROPERTY MONOLITHIC STAINLESS STEEL COMPONENT

Abstract:

An integrally-formed multi-property monolithic stainless steel component, a method of fabricating a multi-property monolithic stainless steel component, and a system for fabricating a multi-property monolithic stainless steel component. The integrally-formed monolithic stainless steel component includes, along a longitudinal direction thereof, one or more non-magnetic regions having an austenitic crystalline grain structure and one or more magnetic regions having a ferritic martensitic crystalline grain structure. The integrally-formed multi-property monolithic stainless steel component is fabricated by a selective laser sintering (SLS) assembly having integrated therein a plurality of sub-assembly components, including a selective powder deposition component, a selective laser sintering (SLS) component, and a localized cooling component.
