FAQs
Q: What makes 304 stainless steel suitable for food processing?
A: Its chromium-nickel alloy prevents corrosion from acidic foods, and its smooth surface meets FDA hygiene requirements.
Q: Can 304 shafts withstand saltwater exposure?
A: While 304 offers better corrosion resistance than 201. 316 grade is recommended for harsh marine environments.
Q: Is heat treatment required for 304 shafts?
A: No—304 is non-hardening and used in its annealed state for maximum ductility.
