Introduction to Stainless Steel
Before diving into the causes of discoloration, it’s essential to have a basic understanding of what stainless steel is and its properties. Stainless steel is an alloy of iron, chromium, and sometimes other metals like nickel or manganese. The chromium content is key to its resistance to corrosion, as it forms a thin, transparent layer of chromium oxide on the surface. This layer, known as the passive layer, protects the underlying metal from reacting with oxygen and moisture, thereby reducing the risk of rust and corrosion.
The Role of the Passive Layer
The passive layer on stainless steel is self-healing, meaning that if it’s damaged, it can reform under the right conditions. However, this layer can be compromised by certain substances and environmental factors, leading to discoloration and potentially even corrosion. Understanding how to maintain and protect this layer is vital for keeping stainless steel appliances looking their best.
