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.

- The requirements for special steel used in low-temperature applications include high toughness, excellent resistance to brittle fracture, and good ductility at low temperatures. It should have a low carbon content to prevent embrittlement, along with specific alloying elements like nickel, manganese, and chromium to enhance its low-temperature properties. Additionally, the steel should have good weldability and corrosion resistance to withstand the harsh conditions often encountered in low-temperature environments.
- Q:What are the different heat treatment processes used for special steel?
- There are several heat treatment processes commonly used for special steel, including annealing, normalizing, quenching, tempering, and case hardening. Annealing involves heating the steel to a specific temperature and then slowly cooling it, which helps to improve its ductility and relieve internal stresses. Normalizing is similar to annealing but involves air cooling the steel after heating, resulting in a more uniform grain structure. Quenching is a process where the steel is rapidly cooled in a liquid medium, such as water or oil, to achieve high hardness and strength. Tempering follows quenching and involves reheating the steel to a lower temperature, reducing its hardness and increasing toughness. Case hardening is a surface hardening process where the steel is heated in the presence of a carbon-rich material, creating a hardened outer layer while maintaining a softer core. These heat treatment processes are used to enhance the mechanical properties and performance of special steel for various applications.

- Q:What are the different methods of improving the creep resistance of special steel?
- There are several methods of improving the creep resistance of special steel, which are designed to enhance its ability to withstand long-term exposure to high temperatures and constant stress. Some of the methods commonly employed include: 1. Alloying: Special steel can be alloyed with specific elements to enhance its creep resistance. The addition of elements such as chromium, molybdenum, tungsten, and vanadium can significantly improve the material's ability to resist creep deformation. These alloying elements form strong carbides or intermetallic compounds, which impede the movement of dislocations and enhance the material's strength and resistance to creep. 2. Heat treatment: Precise heat treatment techniques can be employed to improve the creep resistance of special steel. Processes such as quenching and tempering, annealing, and normalizing can alter the steel's microstructure, leading to the formation of fine-grained and homogeneous structures that offer improved creep resistance. Heat treatment also helps in relieving residual stresses and improving the material's overall strength. 3. Grain refinement: Special steel can be subjected to processes that refine its grain structure, thereby enhancing its creep resistance. Techniques such as grain size reduction through controlled rolling, recrystallization, and severe plastic deformation can lead to the formation of smaller and more uniform grains. This refined microstructure hinders dislocation movement and improves the material's resistance to creep deformation. 4. Precipitation hardening: Special steel can be subjected to precipitation hardening methods, where the material is heated and then rapidly cooled to induce the formation of fine precipitates. These precipitates act as barriers to dislocation movement, improving the material's strength and creep resistance. 5. Surface modification: Special steel can be treated with surface modification techniques to increase its creep resistance. Methods such as shot peening, laser surface melting, and surface coatings can improve the surface integrity, reduce surface roughness, and introduce compressive residual stresses, all of which contribute to enhanced creep resistance. It is important to note that the selection and combination of these methods depend on the specific requirements of the application and the type of special steel being used. The aim is to optimize the material's microstructure, chemical composition, and surface characteristics to achieve the desired creep resistance and ensure long-term performance at elevated temperatures.
