Stainless steel fasteners for commercial use

How to show the rust your strength:

Stainless steel with class

… tough in the long run – but only if the application is right!
Corrosion protection classes

Dear ,

„Which material, which stainless steel is the “right one”?“ The decisive factors are the place of application and the use. The corresponding material properties are strictly defined in corrosion classes.

So that you arealways on the safe side: You will find a small overview here:

A2 AISI-304

Corrosion protection class CRC II = low corrosion resistance
  • resistant to freshwater and
  • conditionally resistant to saltwater and seawater
Main areas of application:
outdoors e.g. for wood screw connections.

A4 AISI-316 /


Corrosion protection class CRC III = medium corrosion resistance
  • resistant to freshwater and
  • resistant to saltwater and seawater
Main areas of application:
in coastal areas, outdoors, the food industry and in ship building and boat building.

Duplex D6

Corrosion protection class CRC VI = high corrosion resistance

Main areas of application:
  • with aggressive media (e.g. salt and chlorine)
  • with high safety standards (e.g. in tunnel construction, swimming pools and leisure pools)
  • under extreme stress (e.g. chains for lifting purposes)
These are only the three most important and most commonly used materials. You can find a lot more about screws, stainless steel materials, corrosion protection classes and care instructions on the Marinetech MT-FastenerFinder > or in our technical information >.

By the way:
Marinetech has switched shipping to environmentally friendly materials!

Paper instead of plastic

Marinetech’s parcels are now largely made without plastic.
The bubble wrap has given way to grey recycled paper, which protects the items just as well against shocks and breakage - but much more sustainably. In future, we will
replace the conventional PP adhesive tape with recycled paper adhesive tape, which, like the cardboard boxes and the transport protection paper, is certified with "The
German Ecolabel | Blue Angel". The cardboard boxes have also become more stable so that our products can travel even the longest distance in perfect condition. A plus also for our employees: The changeover to an automatic cardboard box and the simultaneous reduction of box sizes go hand in hand with a great reduction in workload. Last but not least: We source our packaging material regionally as far as possible, i.e. procurement is simple and fast and long transport routes are avoided.

Our employees are there for you.
