303 in CNC Machining
303 stainless steel is an austenitic alloy with sulfur added to improve machinability over 304. Its machinability makes it a strong choice for precision parts such as gears, shafts, screws, nuts, and bolts.
- Excellent machinability: Sulfur improves machinability compared with 304.
- Precision components: 303 is well suited to gears, shafts, screws, nuts, and bolts.
- Corrosion resistance: 303 combines easy machining with stainless steel corrosion resistance.
Selection note: Stainless steel offers excellent corrosion resistance, strength, and easy cleaning. RapidDirect provides as-machined, electroplated, passivated, powder-coated, polished, and brushed surfaces.
