304/304L Stainless Steel Bar

UNS S30403 (Grade 304/304L)

304/304L stainless steel bar, also known as UNS S30403 and Grade 304/304L, is the low carbon content version of Type 304 generally preferred because it is the “free machining” version. Grade 304/304L exhibits good combination of strength, corrosion resistance and fabricibility making it ideal for almost all industries. Cold working will increase both the hardness and strength, and it does not respond to heat treatment.

Industries that use 304 include:

Used in every conceivable industry

Products partially or completely constructed of 304 include:

  • Architectural paneling, railings & trim
  • Chemical containers, including for transport
  • Food processing equipment
  • Kitchen benches, sinks troughs, equipment & appliances
  • Woven or welded screens for mining, quarrying & water filtration
