The 300 Series Powders are austenitic stainless steels typically used for powdered metallurgy (P/M)
press and sinter applications to make near net shape parts for a variety of industrial applications.
Stainless steel powder 303L is a free machining, austenitic grade that offers moderate corrosion resistance. This stainless steel is sintered in either a partial vacuum or a hydrogren atmosphere to improve ductility and corrosion resistance. 303 Stainless steel powder is a sulfurized grade that is an excellent option for parts that require secondary machining operations, such as food service equipment, pump components and nonmagnetic housings.
