FAQ

Is magnetism a reliable indicator of stainless steel quality in related hardware?

No, magnetism is not a reliable test for stainless steel quality. Austenitic stainless steel (common in marine hardware) is non-magnetic or weakly magnetic, while martensitic/ferritic stainless steel is magnetic. Cold working can make austenitic stainless steel slightly magnetic, but this does not mean it’s inferior. For accurate testing, use professional methods like spectral detection or stainless steel identification liquid.

How to avoid corrosion on stainless steel accessories used with silicone scupper plugs?

To prevent corrosion on stainless steel accessories: 1) Keep the surface clean—wipe away metal dust, organic substances (e.g., food residues), and acid/alkali/salt residues regularly; 2) Avoid exposing the accessories to polluted air for long periods; 3) Store stainless steel parts in a dry, well-ventilated area when not in use. The Silicone Scupper Plug itself is corrosion-resistant and won’t damage stainless steel surfaces.
