304/304L stainless steel bar, also known as UNS S30403 and Grade 304/304L Stianless Steel, is the low carbon content version of Type 304 Stianless Steel generally preferred because it is the “free machining” version. Grade 304/304L Stianless Steel 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 Stainless Steel include:
Used in every conceivable industry
Products partially or completely constructed of 304 Stainless Steel include:
- Architectural paneling, railings & trim
- Chemical containers, including for transport
- Food processing equipment
- Kitchen benches, sinks troughs, equipment & appliances
