Corrosion can occur when an alloy is exposed to moisture and other elements or chemicals which cause the material to deteriorate. Rolled Alloys has put together a list of tips to help you avoid corrosion.
- Choose Stainless Steel: Although all metals can corrode, stainless steels are more resistant to corrosion than other alloys.
- Know your environment: If you don’t know the conditions (acidity, temperatures, loads, other service needs), the wrong alloy can be selected and corrosion be severe. Example: a typical rule of thumb is that corrosion rates double for every ten degree (centigrade) increase in temperature, for a given concentration of an acid.
- Avoid crevice corrosion: Welding and the use of gaskets and proper drainage can reduce access to the crevice.
- Make sure metal surface stays clean and dry: A routine cleaning schedule will reduce the chance of build up where crevices start.
- For applications in or near salt water, stainless steel will corrode in the presence of salts (chlorides). Using a more resistant alloy, like ZERON® 100 or AL-6XN® will provide better protection.
