Stainless Steel 304 vs 316 Cable Ties — Marine & Corrosion Comparison
Stainless steel 304 vs 316 cable ties: corrosion resistance, chemical composition, temperature range, cost, and application comparison for marine and industrial use.
About This Hub
304 and 316 are the two most common stainless steel grades for cable ties. 316 contains 2-3% molybdenum, providing superior resistance to chloride pitting — the primary failure mode in saltwater and chemical environments. This comparison helps you decide when the 30-50% cost premium of 316 is justified.

Frequently Asked Questions
Is 316 always better than 304?
No. For indoor and mild outdoor applications, 304 provides identical mechanical performance at lower cost. 316 is only necessary where chloride exposure (saltwater, de-icing salts, coastal atmosphere) or specific chemical resistance is required.
How can I tell 304 from 316?
Visual inspection cannot distinguish them. Laboratory analysis (XRF or chemical spot test for molybdenum) is required. All our stainless steel ties are clearly marked with grade and heat number for traceability.
