A1: All products offered byOKorder.com are carefully selected from China's most reliable manufacturing enterprises. Through its ISO certifications, OKorder.com adheres to the highest standards and a commitment to supply chain safety and customer satisfaction.
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.

Additionally, steel round bars are readily available in different sizes and grades, allowing for customization based on specific fastener requirements.
- Q: How are steel round bars made?
- Steel round bars are made through a process called hot rolling. It involves heating a large rectangular steel billet until it reaches a malleable temperature. The heated billet is then passed through a series of rolling stands, which progressively reduce its thickness and shape it into a round bar. The first step in the hot rolling process is heating the billet in a furnace at extremely high temperatures, typically around 1200 to 1300 degrees Celsius. This heat makes the steel more pliable and easier to shape. Once the billet is heated, it is fed into a rolling mill. The mill consists of a series of rollers that gradually reduce the thickness and elongate the billet. As the billet passes through each set of rollers, it is squeezed and stretched, gradually forming a round shape. The number of passes through the rolling mill depends on the desired final size and shape of the round bar. During the rolling process, the steel bar is also cooled to prevent overheating and ensure proper metallurgical properties. This can be done through a water spray or air cooling system. After the bar has been shaped and cooled, it is cut into desired lengths. The cut bars are then subjected to further processes such as straightening, surface treatment, and quality testing. These additional steps ensure that the steel round bars meet the required specifications and standards. Overall, the process of making steel round bars involves heating a steel billet, passing it through a series of rolling stands to shape it into a round bar, cooling it, and then cutting it into desired lengths. This process allows for the production of strong and durable round bars that find various applications in industries such as construction, manufacturing, and engineering.
