304 vs 316 Stainless Steel

Both of these two grades of steel both provide an increased resistance against the effects of corrosion in environments near frequently wetting or coastal locations.

They have a chemical composition such that no additional coating is required to protect from the elements.

Whilst these two grades are similar, there is a distinct difference in their chemical make up.

304 Grade 💧 : Iron (~70%), Chromium (~19%), Nickel (~9%), Manganese (2%), and other elements

316 Grade 🌊 : Iron (~65%), Chromium (~17%), Nickel (~12%), Molybdenum (2.5%), Manganese (2%), and other elements

This addition of Molybdenum creates a much more resistant metal against saltwater and other corrosive conditions. This increased resistance comes with an increased cost of material. Depending on your project needs, this can be justified for its prolonged installed lifetime.

The same as any structural element, stainless connectors should be inspected and maintained on a regular basis to see any issues and remove or minimise any build-up that could accelerate the process of corrosion.

No metal is technically stain-proof. Stainless in essence means stain less.

💧 For areas in regular contact with freshwater and frequent wetting and drying, Stainless Steel 304 is recommended.
🌊 For areas close to an unsheltered surf coast, Stainless Steel 316 is recommended.
