Does Stainless Steel ever corrode?

One of the misconceptions that we sometimes come across is that stainless steel is corrosion-resistant. We all know it to be a high quality, durable material, often used in the harshest of environments, but occasionally it may be subject to ‘tea-staining’ (or surface rust). Whether this happens depends on a number of factors, including:

  • the grade of stainless steel specified – by the way, all our Jakob materials are made from the highest grade (316) – often called marine grade
  • the environment in which the material is to be used
  • the exposure to rain water and sea water
  • the surface finish – for example, a brushed finish which has fine grains running through it can cause problems as the grains can trap salts and other contaminants

The build-up of salt and contaminants can damage the chromium oxide layer, causing staining. So for example, in a higher risk area, rather than using a brushed-finish, a smooth finish which is then electro-polished would provide extra protection.

If there is a risk of surface staining, we advise a simple routine of cleaning – nothing more than washing the surface with soapy water every 3 to 6 months and then rinsing it off with clean water. In extreme circumstances (where salt levels are high) the application of a coat of a proprietary, lanolin-based solution after cleaning would protect the stainless steel further and cut down the required cleaning frequency.

So although in some cases, stainless steel may require a cleaning regimen to maintain its corrosion resistant properties, in our experience it’s well worth it – to maintain your beautifully elegant stainless steel finish for many years.
