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 main factors affecting the formability of special steel?
- Several factors influence the formability of special steel, similar to other types of steel. These factors encompass the composition, microstructure, mechanical properties, temperature, and strain rate of the steel. The composition of special steel plays a vital role in determining its formability. The presence of alloying elements, such as chromium, nickel, molybdenum, and vanadium, can significantly impact the steel's ability to be shaped. These elements have the power to modify the steel's strength, ductility, and resistance to deformation. Another crucial factor influencing the formability of special steel is its microstructure. Fine-grained steels generally exhibit superior formability compared to coarse-grained steels. Additionally, the existence of non-metallic inclusions, like sulfides and oxides, can act as stress concentrators and promote crack formation, thereby influencing formability. The mechanical properties of special steel, including yield strength, tensile strength, and elongation, directly affect its formability. Steels with higher yield strength typically pose greater difficulty in shaping as they require more force for deformation. However, steels with high elongation can undergo more significant plastic deformation before failure, making them more formable. Temperature is also a critical factor impacting the formability of special steel. Elevated temperatures enhance the steel's ductility and make it easier to shape. This is due to the reduction in yield strength and increased movement of dislocations within the crystal structure. However, excessively high temperatures can lead to grain growth, negatively impacting formability. The strain rate, which refers to the rate of deformation applied to the steel, also influences formability. Higher strain rates can result in strain hardening, making the steel stronger but less formable. Conversely, lower strain rates allow for greater plastic deformation and improved formability. In conclusion, achieving the desired formability and shaping capabilities of special steel in various applications necessitates an understanding and optimization of its composition, microstructure, mechanical properties, temperature, and strain rate.
