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-rolled and a forged steel round bar?
- The main difference between a hot-rolled and a forged 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 of steel to a high temperature and then shaping it into the desired form using rollers. This process allows for a high volume of production and a wide range of sizes and shapes. As the steel is heated and shaped, it undergoes significant deformation and recrystallization, resulting in a uniform grain structure. Hot-rolled steel round bars have a rougher surface finish and can have varying levels of internal stress due to the cooling process. They are commonly used in applications where strength and cost-effectiveness are important, such as construction, manufacturing, and general fabrication. On the other hand, forged steel round bars are produced by applying extreme pressure to a heated billet or ingot of steel, typically using a hammer or a press. This process creates a much stronger and more durable product compared to hot-rolled steel. The intense pressure applied during forging aligns the steel's grain structure, resulting in improved mechanical properties such as increased strength, toughness, and resistance to fatigue and impact. Additionally, the forging process eliminates internal voids and porosity, making forged steel round bars more reliable and less prone to failure. Due to the high level of customization and precision involved in forging, these round bars are often used in critical applications that require superior strength and performance, such as aerospace, automotive, and oil and gas industries. In summary, the main differences between hot-rolled and forged steel round bars lie in their manufacturing processes and resulting properties. Hot-rolled steel offers cost-effectiveness and a wide range of sizes and shapes, while forged steel provides superior strength, durability, and reliability. The choice between the two depends on the specific application and the desired performance characteristics.
