Introduction to Rust and Stainless Steel
Stainless steel is a type of metal that is resistant to corrosion, stains, and rust. It is widely used in various applications such as kitchen utensils, appliances, medical equipment, construction materials and many more. However, even though stainless steel has excellent resistance against rusting or staining, it may still get corroded under certain circumstances.
Rust is the common name for a very common compound known as iron oxide. Rust forms when iron or its alloys come into contact with water and oxygen over an extended period of time. The presence of saltwater or other corrosive agents can speed up the process of rust formation on stainless steel surfaces.
Even though stainless steel contains chromium that makes it highly resistant to corrosion and oxidation processes; if exposed to harsh conditions like high humidity or salt-laden air for prolonged periods – it can lead to pitting corrosion which might result in rust formation.
Therefore it’s essential to clean your stainless steel regularly and take steps to prevent any potential damage from occurring that could lead to unwanted rust appearing on your otherwise beautiful surfaces.
Causes of Rust on Stainless Steel
Stainless steel is a highly durable and corrosion-resistant material, but it’s not entirely immune to rust. Here are some of the common causes of rust on stainless steel:
Exposure to Chlorides
Chlorides are present in many everyday substances such as salt, bleach, and cleaning products. When stainless steel comes into contact with chlorides, it can cause pitting corrosion which leads to rusting.
Scratches or Damage to Surface
Even though stainless steel has a protective layer that helps prevent rust from forming, scratches or damage on this surface can compromise its integrity. Once the protective layer is breached, the underlying metal becomes susceptible to oxidation.
Cleaning with Abrasive Materials
Abrasive cleaners such as wire brushes or harsh chemicals like hydrochloric acid can scratch the surface of stainless steel and remove its protective layer. This makes it more vulnerable to corrosion and rust over time.
Contact with Carbon Steel
When carbon steel comes into contact with stainless steel in wet conditions for prolonged periods, galvanic corrosion can occur. This happens when two dissimilar metals come into contact resulting in an electrochemical reaction that leads to corrosion.
Knowing these causes of rust on stainless steel will help you take preventive measures while caring for your equipment or household items made from this material.
