Duplex H9 10mm Stainless Steel Rectangular Pipe Decoiling AISI SS304 306
why stainless steel generally doesn’t rust or tarnish?
Besides having the protective layer of chromium, there is another reason why stainless steel generally doesn’t rust or tarnish. This is also due to the fact that stainless steel develops an oxide layer when it’s exposed to air. This layer hence protects the metal from corrosion. What is more fascinating is that even though the metal gets damaged or nicked, the oxide layer will still develop and keep stainless steel tarnish under control.
However, this doesn’t mean your jewelry is 100% safe. There are cases when even the best stainless steel jewelry will rust and tarnish. The layer of chromium in your jewelry could get damaged or it could fail to protect your jewelry. When this happens, the other metals found in this type of jewelry will react to oxygen and your jewelry could lose its sparkle and start rusting.
Additionally, the durability of your stainless steel jewelry will also depend on the environment you’re exposing it to. Even though it has the protective layers, if you expose your jewelry to harsh conditions, they will affect the metal and cause tarnishing. So, you should keep your stainless steel pieces away from seawater, because it will react.
