Stainless steel is renowned for the following two properties; resistance to corrosion and low maintenance requirements. Within the austenite group two particular stainless steel grades are of particular interest, known as AISI:
possesses the property of corrosion resistance in natural atmospheric environments, however, only non-acid based cleaning solutions can be used.
(an addition of an extra 2 – 3% molybdenum and nickel), has enhanced corrosion resistance suitable for more aggressive atmospheric environments, is anti-allergenic (2), of low maintenance and suitable for all cleaning solutions including acid based (except hydrochloric acid), as long as thoroughly rinsed with clean water afterwards.
It is important to clean stainless steel regularly. Initially, wash down the surface using soapy water or a mild detergent. Always thoroughly rinse the cleaning agent away with clean water. To complete the cleaning procedure dry/polish the item with a soft, dry cloth.
Within aggressive conditions, such as offshore, marine and swimming pool environments, it is especially relevant to ensure that cleaning maintenance occurs regularly.
If spots appear on the surface it is not due to the stainless steel, but to impurities in the water, the air or to cleaning agents that have not been thoroughly removed from the surface. Spots can be avoided by careful cleaning. If discoloration or spots occur they can be removed by using special polishing agents for stainless steel. Again rinse thoroughly with clean water and polish with a soft, dry cloth.
what to avoid
Strong abrasive materials
Acid based cleaning solutions, except for hydrochloric acid, may be used on AISI 316 stainless steel as long as thoroughly rinsed with clean water afterwards
