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.

- Q: How does tungsten contribute to the properties of special steel?
- Tungsten is a critical element that contributes significantly to the properties of special steel. One of the major benefits of tungsten in steel is its ability to enhance strength and hardness. It forms a solid solution with iron, resulting in a fine-grained microstructure that increases the overall toughness and wear resistance of the steel. Additionally, tungsten helps to improve the high-temperature strength of special steel. It has a high melting point and maintains its strength even at elevated temperatures, making it ideal for applications that require resistance to heat and thermal stress. This characteristic allows special steel with tungsten to be used in environments with extreme temperatures, such as in gas turbines, rocket nozzles, and cutting tools. Tungsten also plays a crucial role in improving the corrosion resistance of special steel. It forms stable carbides that protect against corrosion and erosion, making the steel more durable and long-lasting. This is particularly valuable in industries where the steel is exposed to corrosive environments, such as chemical processing, marine applications, and oil and gas exploration. Furthermore, tungsten contributes to the machinability of special steel. It helps in reducing the built-up edge during cutting operations, resulting in improved surface finish and longer tool life.
