You often find stainless steel in marine applications and there is good reason for this. It is widely recognised as the ideal material for marine applications because it has excellent corrosion resistance as well as good stability, appearance, durability, lustre, strength and stiffness.

stainless steel in marine applications

Marine environments can be very demanding, with factors like high salt content, water flow rates, pressure and temperature all coming into play. Stainless steel structures can usually withstand these factors and ensure that complex projects can go ahead that may otherwise be impossible.

As an example of stainless steel in marine applications, grade 304 stainless steel is often used as the material for fittings in boating applications, whereas 316 stainless steel (UNS S31600/S31603 – commonly termed ‘marine grade’ stainless) can be found in approximately 90% of marine applications. 304 and 316 stainless steels are austenitic metals which can be seen due their metallurgical structure which means they possess excellent ductility, good strength, non-magnetic properties, good weldability, and very good corrosion resistance.

Duplex Stainless Steel is also widely used in marine applications, usually ones that require a higher yield strength and better corrosion resistance.

As well as boating applications, stainless steel can be found far and wide in marine applications, in everything from oil rigs, piers and vessels to floating homes.

Stainless steel is ‘fit for purpose’

There are lots of factors to consider when choosing which type of stainless steel is right for your project. These include:

 

There are many different types of stainless steel, and each one has different advantages and uses. Look at these examples:

Corrosion

Corrosion is one of the main ‘enemies’ that have to be fought against in marine environments. Consequently, it is one of the main reasons why stainless steel is used.

There are different types of corrosion that must be combatted. Interestingly, many corrosion problems can be avoided by use of cathodic protection.

Some of the different types of corrosion are:
