Heat stains occur when heat reacts with the chromium oxide layer that protects the steel from corrosion. When this layer is damaged by high temperatures, the underlying metal can oxidize, causing various color changes.
Exposure to high temperatures is one of the primary causes of heat stains. This can happen during cooking, welding, or any other high-heat processes. The temperature creates oxide layers on the surface, with colors ranging from light straw to dark purple, depending on the degree of heat.
Oxidation occurs when stainless steel is exposed to both heat and oxygen. This reaction creates a thin oxide layer on the surface, resulting in a rainbow-like discoloration called heat tint. The presence of oxygen accelerates the formation of these stains.
Stainless steel is an alloy primarily composed of iron, chromium, and sometimes nickel. Chromium is essential because it forms a protective layer on the surface, preventing rust and corrosion. However, when exposed to high temperatures, this protective layer can break down, making the steel more susceptible to staining and discoloration.
The thin oxide layer that forms on stainless steel during heat exposure is responsible for the rainbow-like appearance of heat stains. This layer not only signifies oxidation but also indicates that the protective chromium oxide has been compromised, making the steel more vulnerable to further damage.
Heat streaks are light discolorations from brief, moderate heat exposure, appearing as faint lines or patches and are often the easiest to remove.
Burn marks are darker and more severe stains resulting from prolonged exposure to very high temperatures. These marks can be more challenging to remove and may require more intensive cleaning methods.
Rainbow stains, also known as heat tints, are iridescent colors that appear due to the formation of thin oxide layers during heat exposure. These colors can range from blue to purple and indicate varying levels of oxidation.
