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: What is the difference between a hot-finished and a cold-finished steel round bar?
- The manufacturing process and resulting physical properties distinguish hot-finished and cold-finished steel round bars. Hot-finished bars are made by subjecting the steel to high temperatures in a furnace, followed by rolling processes. This method allows for greater malleability, making it easier to shape the steel to its desired dimensions. Consequently, hot-finished bars often have a rougher surface and may exhibit imperfections such as scaling and decarburization. Nonetheless, the high-temperature process enhances the steel's mechanical properties, including tensile and yield strength, making it suitable for applications requiring greater strength and durability. Conversely, cold-finished bars undergo a distinct manufacturing process. They are formed by cold rolling the steel at room temperature, resulting in a smoother surface finish and tighter dimensional tolerances compared to hot-finished bars. The absence of high temperatures eliminates scaling and decarburization, yielding a more uniform and cleaner appearance. Although cold-finished bars may have slightly lower tensile and yield strength than their hot-finished counterparts, they offer improved dimensional accuracy and a smoother surface, making them ideal for precision machining or applications that prioritize aesthetics. To summarize, the disparities between hot-finished and cold-finished steel round bars lie in the manufacturing process, surface finish, dimensional accuracy, and mechanical properties. Hot-finished bars provide greater strength and suit applications that prioritize durability, whereas cold-finished bars offer superior surface finish and dimensional accuracy, making them ideal for precision machining or applications where aesthetics are crucial.
