Frequently Asked Questions
304 vs 316 — what's the difference for hex bolts?
316 contains 2-3% molybdenum, providing significantly better resistance to chloride corrosion (seawater, coastal environments, pool chemicals). 304 is suitable for most general corrosion-resistant applications. 316 costs roughly 30-50% more than 304.
