304L stainless steel powder applications by industry
| Industry | Typical parts | Why 304L stainless steel | Specify in your RFQ |
|---|---|---|---|
| Food and beverage | Fittings, nozzles, process-line parts | Low-carbon austenitic stainless with good weldability and general corrosion resistance | Surface finish, cleaning, chloride exposure (316L if chlorides are present) |
| General industry and repair | Brackets, housings, DED build-up on 304 parts | Matches common wrought 304 hardware | Base material, deposition route, machining |
| Cryogenic service | Low-temperature fittings and supports | Austenitic stainless keeps toughness at low temperature | Test temperature, ferrite content, NDE |
Designations
- 304L
- UNS S30403
- EN 1.4307
Use 304L, UNS S30403, or EN 1.4307 in RFQs. Choose 316L instead when chlorides or pitting resistance drive the material decision.
