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: What are the different corrosion protection methods for steel rebars?
- Steel rebars commonly used in reinforced concrete structures have various corrosion protection methods available. These methods aim to prevent or minimize rebars' corrosion, which can significantly weaken the overall structure. 1. Concrete Cover: An effective corrosion protection method involves providing a sufficient thickness of concrete cover over the rebars. This creates a physical barrier, preventing the rebars from being exposed to corrosive elements. 2. Galvanization: Another method is to coat the rebars with zinc through a process called galvanization. This protective layer acts as a sacrificial anode, corroding before the rebars and enhancing their resistance to corrosion. 3. Epoxy Coating: A popular approach is applying a layer of epoxy resin over the rebars. This coating acts as a barrier, preventing moisture and corrosive substances from reaching the rebars. 4. Cathodic Protection: An electrochemical method known as cathodic protection involves using a sacrificial anode or an impressed current system. In a sacrificial anode system, a more reactive metal like zinc or magnesium is connected to the rebars, sacrificing itself to prevent corrosion. In an impressed current system, an external power source supplies a protective current to the rebars, preventing corrosion. 5. Corrosion Inhibitors: Chemicals can be added to the concrete mix or applied as a surface treatment to act as corrosion inhibitors. These substances create a protective film on the rebars' surface, blocking corrosive agents' access and preventing corrosion. 6. Stainless Steel Rebars: An effective method is to use stainless steel rebars, which have high resistance to corrosion. This makes them suitable for structures exposed to aggressive environments. It is important to consider various factors, such as environmental conditions, expected service life, and cost, when selecting the appropriate corrosion protection method. Regular inspection and maintenance of the system are also necessary to ensure its long-term effectiveness.
- Q: What are the different types of steel rebars used in high-rise buildings?
