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: What is the difference between hot-rolled and cold-rolled steel billets?
- Hot-rolled steel billets and cold-rolled steel billets are two types of steel that undergo different manufacturing processes, resulting in distinct characteristics and properties. When producing hot-rolled steel billets, the steel is heated to a high temperature and then rolled while still hot. This process allows for easy shaping and forming into various sizes and shapes. Additionally, hot-rolling creates a rough surface finish and a scaled outer layer due to exposure to high temperatures. Generally, hot-rolled steel billets have a larger grain structure, which can result in a less precise and uniform final product. However, they also possess improved mechanical properties, such as higher strength and toughness, making them suitable for applications where strength is important, but surface finish is not a priority. In contrast, cold-rolled steel billets are produced by cooling the steel to a low temperature and rolling it at room temperature. This process allows for tighter dimensional tolerances and a smoother surface finish compared to hot-rolled steel billets. Additionally, cold-rolling results in a more refined grain structure, which enhances the overall strength, hardness, and durability of the steel. Cold-rolled steel billets are commonly used in applications where precise dimensions, surface finish, and uniformity are required, such as in the automotive, construction, and appliance industries. To summarize, the main difference between hot-rolled and cold-rolled steel billets lies in the manufacturing processes and resulting properties. Hot-rolled steel billets are formed at high temperatures, resulting in a rough surface finish and larger grain structure. Cold-rolled steel billets, on the other hand, are formed at room temperature, leading to tighter dimensional tolerances, a smoother surface finish, and a more refined grain structure. The choice between hot-rolled and cold-rolled steel billets depends on specific requirements and applications, with hot-rolled steel billets being preferred for their superior strength and cold-rolled steel billets for their precise dimensions and surface finish.
