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 a turned and a ground steel round bar?
- A turned steel round bar is a cylindrical steel rod that has been machined using a lathe to achieve a smooth and precise finish. This process removes material from the surface of the bar, resulting in a dimensional accuracy and a polished appearance. On the other hand, a ground steel round bar is also a cylindrical steel rod, but it undergoes a different machining process called grinding. Grinding involves using an abrasive wheel or belt to remove material from the bar's surface, resulting in a more precise diameter and a smoother finish compared to turning. In summary, the main difference between turned and ground steel round bars lies in the machining process used. Turning removes material through a lathe, while grinding involves an abrasive process for a more accurate and polished result.
- Q: What is the difference between a smooth and a precision ground steel round bar?
- A smooth steel round bar has a surface that is free from any roughness or irregularities, providing a polished and sleek appearance. On the other hand, a precision ground steel round bar undergoes a specialized grinding process to achieve tight tolerances and a high degree of accuracy in its dimensions.
