AISI 303 stainless steel (UNS S30300) is a free-machining grade developed for easy cutting, belonging to the 18-8 series. It features higher sulfur content to reduce cutting tool resistance, improving machinability while maintaining good mechanical properties. However, its corrosion resistance is lower than AISI 304.
