Q4: What makes stainless steel stainless?
A4: Stainless steel must contain at least 10.5 % chromium. It is this element that reacts with the oxygen in the air to form a complex chrome-oxide surface layer that is invisible but strong enough to prevent further oxygen from "staining" (rusting) the surface. Higher levels of chromium and the addition of other alloying elements such as nickel and molybdenum enhance this surface layer and improve the corrosion resistance of the stainless material.
Q5: Can stainless steel rust?
A5: Stainless does not "rust" as you think of regular steel rusting with a red oxide on the surface that flakes off. If you see red rust it is probably due to some iron particles that have contaminated the surface of the stainless steel and it is these iron particles that are rusting. Look at the source of the rusting and see if you can remove it from the surface.

- Q: Is special steel resistant to chemical corrosion?
- Yes, special steel is generally resistant to chemical corrosion. Special steel, also known as stainless steel, is a type of alloy that contains a minimum of 10.5% chromium. The addition of chromium in the steel composition forms a passive oxide layer on the surface, which acts as a protective barrier against corrosion. This oxide layer is highly stable and prevents the steel from reacting with various chemicals and corrosive substances. Additionally, special steel may also contain other alloying elements such as nickel, molybdenum, and titanium, which further enhance its resistance to chemical corrosion. These elements increase the steel's ability to withstand exposure to acids, alkalis, salts, and other corrosive agents commonly found in industrial and environmental settings. However, it is important to note that the resistance of special steel to chemical corrosion may vary depending on the specific grade and composition. Different grades of stainless steel offer different levels of corrosion resistance, and it is crucial to select the appropriate grade based on the intended application and the specific corrosive environment. In summary, while special steel is generally resistant to chemical corrosion, the specific resistance can vary depending on the grade and composition. Therefore, it is essential to consider the specific requirements and consult with experts to choose the most suitable special steel for a particular application.
