FAQ:
Q1: How soon can we receive the product after purchase?
A1: Within three days of placing an order, we will begin production. The specific shipping date is dependent upon international and government factors, but is typically 7 to 10 workdays.
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 bright and a hot rolled steel round bar?
- The difference between a bright and a hot rolled steel round bar lies in their manufacturing processes and resulting characteristics. A hot rolled steel round bar is produced by heating the steel billet or ingot to a high temperature and then rolling it through a series of rolling mills to achieve the desired shape. This process results in a rough surface texture with a scale layer on the outside. Hot rolled steel bars are typically used for structural applications where strength and durability are important. They are known for their rough appearance and may require further processing, such as grinding or machining, to achieve a smooth surface finish. On the other hand, a bright steel round bar, also known as a cold drawn or cold finished bar, is produced by drawing the hot rolled steel bar through a series of dies at room temperature. This process helps to improve the dimensional accuracy, surface finish, and mechanical properties of the steel. The resulting bright steel bar has a smooth and shiny surface, free from scale or rough texture. Bright steel bars are commonly used in applications where a superior surface finish and tight dimensional tolerances are required, such as in the manufacturing of precision components or for decorative purposes. In summary, the main difference between a bright and a hot rolled steel round bar lies in their surface finish, dimensional accuracy, and applications. Hot rolled steel bars have a rough surface texture and are suitable for structural applications, while bright steel bars have a smooth and shiny surface finish, making them ideal for precision or decorative applications.
