Q2: What makes stainless steel stainless?
A2: 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.
Q3: Can stainless steel rust?
A3: 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 are steel billets rolled into rails?
- The process of hot rolling is employed to transform steel billets into rails. This involves a sequence of steps. To begin, the steel billets are subjected to intense heat in a furnace, raising their temperature to approximately 1200°C. This elevated temperature renders the steel more pliable and easier to mold. Once the billets reach the desired temperature, they are transferred to a rolling mill. Within the rolling mill, the heated steel billets are guided through a succession of rolling stands. These stands consist of pairs of sizeable rolls that gradually diminish the thickness and alter the shape of the billets. As the billets pass through each stand, the rolls apply significant pressure, causing the steel to elongate and adopt the characteristics of a rail. As the billets progress through the rolling mill, they gradually assume the dimensions of rails. The rolling process also confers strength and durability upon the rails, making them suitable for a range of applications, such as railway tracks. During the rolling process, it is common to employ water or oil to cool the rolls and prevent overheating. This cooling also aids in maintaining the desired temperature of the steel billets as they traverse the rolling mill. Once the steel billets have been transformed into rails, they are cut to the desired lengths and undergo further processing, such as straightening and heat treatment, to ensure they meet the required specifications. In conclusion, the hot rolling process is utilized to convert steel billets into rails. This entails heating the billets, guiding them through a series of rolling stands, and gradually shaping them into rails with the desired dimensions. The resulting rails are then subjected to additional processing to prepare them for various applications.
