Abstract: A fuel injector includes an injector body having an injector cavity, a valve seat, and a flow control member. The valve seat is comprised of a metallic material having a grain size of 0.05-5.0 μm. Additionally, the fuel injector includes a nozzle valve element positioned in the injector cavity and configured to move between an open position in response to the flow control member being spaced apart from the valve seat and a closed position in response to the flow control member engaging the valve seat. Fuel is configured to flow from the fuel injector in response to the nozzle valve element being in the open position.
