Advanced Soft Magnetic Stainless Steel for Electric Fuel Injector 890476

An improved soft magnetic stainless steel has been developed which is effective in the response of electric fuel injectors. The chemical compositions of this steel is 10%Cr-3%A1-0.2%Pb. The steel provides 25% better magnetic response to pulse signal and 40% larger specific resistance than a soft magnetic 13%Cr-0.8%Si steel which is previously used for the core of electric fuel injectors. In addition this steel has a favorable magnetic properties together with corrosion resistance, cold forgeability and machinability.
