Stainless Steel 303 Annealed is the easiest stainless alloy to machine among austenitic grades, designed specifically to enhance CNC performance without compromising corrosion resistance. The annealed condition ensures improved ductility, smoother cutting, and minimal tool wear, making it ideal for complex, high-speed precision machining.
With added sulfur content, SS303 offers superior chip-breaking ability, allowing clean finishes, lower cycle times, and longer tool life during CNC milling, turning, and drilling operations. Though it offers slightly lower corrosion resistance than SS304, SS303 is widely trusted for components in automotive, aerospace, instrumentation, and industrial automation.
TECHNO delivers SS303 annealed bars and billets ready for direct CNC operation—ideal for high-volume production environments demanding dimensional accuracy and process repeatability.
| COMPATIBLE WITH | Hardware, lasteners, valve patt, nozzles and brim |
