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 limitations of using special steel in high-stress applications?
- Using special steel in high-stress applications comes with several limitations. Firstly, the cost of special steel can be significantly higher compared to other materials, making it less feasible for projects or industries with budget constraints. Secondly, the availability and sourcing of special steel can be a challenge, leading to potential delays in production or construction timelines. This becomes problematic in high-stress applications where time is of the essence. In addition, special steel may have limitations in terms of its structural integrity. Although it is generally stronger and more resistant to wear and tear than regular steel, it still has load-bearing capacity limits. Therefore, in extremely high-stress applications, special steel may not be the most suitable choice. Moreover, working with special steel can be more difficult than working with other materials. It may require specialized equipment or techniques for cutting, welding, or shaping, thereby adding complexity and cost to the manufacturing process. Lastly, special steel may have limitations in terms of its corrosion resistance. While it is generally more resistant to corrosion compared to regular steel, it can still rust or degrade if not properly maintained or exposed to harsh environments. This is a concern in high-stress applications where the material's durability and longevity are crucial. Overall, while special steel offers many benefits in high-stress applications, it is important to carefully consider its limitations in terms of cost, availability, load-bearing capacity, workability, and corrosion resistance. These factors should be thoroughly evaluated to determine the most suitable material for a specific high-stress application.
