Why AISI 316L for Marine Chains
Marine environments destroy ordinary chains. Salt spray, galvanic currents, and continuous immersion require a material that can resist them all: AISI 316L stainless steel.
What makes 316L special? Its chemical composition includes 2–3% molybdenum — an element that significantly boosts resistance to chloride‑induced corrosion. Unlike 304 stainless steel, 316L stands up to seawater, acidic residues, and coastal humidity.
At Boyuan Metal, we apply this material science to our DIN 766 chains. The result: a chain that lasts for decades with minimal maintenance. Just rinse with fresh water after use and inspect periodically. No rust, no surprise failures.
Choose the right steel — choose 316L.
