The most popular type of stainless steel in the marine environment is grade 316. With lowered chromium content, increased nickel and molybdenum added to the mixture, the material becomes more resistant to chlorides. That's why grade 316 stainless is often used in more corrosive environments where the material will be exposed to chemical, solvent or salt water corrosion and makes it the preferred material for marine construction. Please enquire with our sales department for different grade 316 fasteners we can offer.
