304/304L Machining

A Guide to stainless steel 304 CNC Machined Parts: Properties, Applications and Design Considerations

What is 304?304 Stainless Steel CNC Milled Track

304 is the most common stainless steel used globally. It is chosen for its excellent corrosion resistance and value for money.

304 and other austenitic steels also offer a balance of strength and workability. 

304L is the extra low carbon form of 304 which has improved resistance to pitting and crevice corrosion in chloride bearing environments.

The most common form of 304 is 18/8 – which contains 18% chromium and 8% nickel.

Main Attributes of Stainless 304:

  • Can withstand corrosion from most oxidising acids
  • Easy to sanitize due to its durability
  • Excellent toughness
  • Susceptible to corrosion from chloride solutions and saline environments
  • Aesthetically pleasing
  • Ease of cleaning
  • Outstanding welding characteristics
  • Good heat resistance – oxidation resistance in intermittent use up to 870°c and continuous use up to 925°c, however continuous use at 425-860°c is not recommended. In this instance, 304L is recommended.
