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: Can steel round bars be used for making connecting rods?

- Q: Can steel round bars be used for making universal joints?
- Yes, steel round bars can be used for making universal joints. Steel round bars are commonly used in the manufacturing of universal joints due to their strength, durability, and ability to handle high torque and rotational forces.
- Q: What is the difference between a hot-rolled and a cold-drawn steel round bar?
- The main difference between a hot-rolled and a cold-drawn steel round bar lies in the manufacturing process and the resulting properties of the finished product. Hot-rolled steel round bars are produced by heating a billet or ingot at a high temperature, typically around 1100 to 1300 degrees Celsius, and then rolling it into the desired shape and size. This process results in a rougher surface finish and larger tolerances compared to cold-drawn bars. Hot-rolled bars are generally less precise in dimensions and may have some surface defects such as scale or rust. On the other hand, cold-drawn steel round bars are manufactured by pulling a hot-rolled bar through a die at room temperature. This process reduces the diameter and enhances the surface finish of the bar, resulting in a smoother and more precise product. Cold-drawing also improves the mechanical properties of the steel, such as increased strength, hardness, and improved surface quality. The cold-drawing process also provides closer dimensional tolerances, making cold-drawn bars suitable for applications that require higher precision. In summary, the difference between a hot-rolled and a cold-drawn steel round bar lies in the manufacturing process, resulting in different surface finish, dimensional tolerances, and mechanical properties. Hot-rolled bars are produced at high temperatures, have a rougher surface, and larger tolerances, while cold-drawn bars are manufactured at room temperature, have a smoother surface, closer dimensional tolerances, and enhanced mechanical properties. The choice between the two depends on specific application requirements and the desired characteristics of the finished product.
- Q: How do you determine the strength of a steel round bar?
- The strength of a steel round bar can be determined through various methods, but the most common approach is by conducting a tensile test.
