How Stainless Steel Can Help in Marine Fastening

If your fastening is outdoors or exposed to heavy marine like environments then we recommend the use of stainless steel to prevent your fastening from corrosion.

Stainless steel processes higher corrosion resistant materials than other materials such as zinc. However, there are many types of stainless steel and if you want the best corrosion prevention than 316 stainless steel is the best option.

316 stainless steel is made up from 16% chromium, 10% nickel and 2% molybdenum. The increase in molybdenum does make this alloy a little more costly, but it also increases the alloy’s corrosion resistance – especially against chloride and chlorine – making 316 ideal for salt-water applications.

If cost is something that effects your fastener decision than 304 stainless steel is the better option. Made from 18% chromium and 8% nickel this alloy is some of the most common materials used to make fasteners. Its high percentage of chromium makes it resistant to oxidation making it great for storage tanks and electrical enclosures.

In short, if your application is in areas of high marine like environments, the use of 316 stainless steel is recommended. If your environment is drier and has less corrosive factors than the cost effective 304 stainless steel is the best choice.
