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: How does special steel withstand extreme temperatures?
- Due to its unique composition and production process, special steel possesses the ability to endure extreme temperatures. An essential factor in achieving this is the incorporation of alloying elements such as chromium, molybdenum, and nickel, which enhance the steel's resistance to heat. These elements react to form stable oxides on the steel's surface, forming a protective shield against oxidation and corrosion at high temperatures. Furthermore, special steel undergoes specific heat treatment methods like quenching and tempering, which refine its microstructure and enhance its mechanical properties. This process strengthens the steel, enabling it to maintain its strength and hardness even under harsh temperature conditions. In addition, the manufacturing process of special steel requires precision and control over the cooling rate. This controlled cooling prevents the formation of brittle phases, ensuring that the steel maintains its toughness and ductility at both high and low temperatures. Moreover, the grain size of special steel is meticulously regulated through techniques like grain refinement, resulting in a more uniform and fine-grained microstructure. This fine-grained structure enhances the steel's ability to resist thermal fatigue and creep, enabling it to endure prolonged exposure to extreme temperatures without significant degradation. Overall, the combination of alloying elements, specialized heat treatment processes, controlled cooling, and refined microstructure renders special steel highly capable of withstanding extreme temperatures while preserving its structural integrity and mechanical properties.
- Q: Can special steel be used for making chemical processing equipment?
- Yes, special steel can be used for making chemical processing equipment. Special steels, such as stainless steel, are often preferred for such applications due to their excellent corrosion resistance, high temperature resistance, and durability. Chemical processing equipment often deals with corrosive substances or operates at high temperatures and pressures, making it essential to use materials that can withstand these conditions. Special steel alloys are specifically designed to have superior resistance to corrosion, including resistance to acids, alkalis, and other aggressive chemicals. Additionally, these steels can maintain their mechanical properties even at elevated temperatures, ensuring the integrity and safety of the equipment. Therefore, special steel is a suitable choice for making chemical processing equipment.
- Q: How does special steel resist wear and tear?
- Special steel resists wear and tear due to its unique composition and manufacturing process. It is made with a higher percentage of alloying elements such as chromium, nickel, and molybdenum, which enhance its hardness, strength, and corrosion resistance. This increased hardness enables the steel to withstand abrasion, friction, and impact, making it highly durable and resistant to wear and tear.
