 Characteristics of  Chinese Standard Round Bar of Grade: Q195, Q235, Q345

1. The steel in which the main interstitial alloying constituent is carbon in the range of 0.12–2.0%.

2. As the carbon percentage content rises, steel has the ability to become harder and stronger through heat treating; however it becomes less ductile.

3. Quality should be in conformity with the specification of the manufacturer. Quantity and packing conditions should be in conformity with the term in the contract.

4. Regardless of the heat treatment, higher carbon content reduces weld ability. In carbon steels, the higher carbon content lowers the melting point.

Q:What is the difference between a circle and round steel continuous casting
The first two density is not the same, the round billet continuous casting billet is molten steel into round billet crystallizer, after two cold water cooling, solidification formation, density is small; bar is formed by the billet or round billet rolled steel products, good density, better mechanical properties than the same size of billet. Second, round billet is the raw material for steel rolling, and the bar is the final product sold as steel.
Q:What is the difference between a bright and a rough turned steel round bar?
A bright turned steel round bar and a rough turned steel round bar differ primarily in their surface finish and the level of precision involved in their manufacturing processes. A bright turned steel round bar has a smooth, shiny surface finish. This is achieved by subjecting the bar to additional processes such as polishing or grinding after the initial turning operation. The bright surface finish gives the bar an aesthetically pleasing appearance and can also provide improved corrosion resistance. On the other hand, a rough turned steel round bar has a more textured surface finish. It is typically obtained directly from the turning operation without any additional processes to refine the surface. The rough surface finish may have visible tool marks and a slightly uneven texture. In terms of manufacturing precision, a bright turned steel round bar is typically more accurate and precise in terms of its dimensions and tolerances. The additional processes involved in achieving a bright surface finish also allow for tighter control over the bar's specifications. This makes bright turned bars suitable for applications where precise dimensions and tolerances are critical. In contrast, a rough turned steel round bar may have slightly looser tolerances due to the nature of the turning process and the lack of additional refining operations. However, the rough turned bars can still meet the requirements of many applications that do not require high precision. Overall, the choice between a bright and a rough turned steel round bar will depend on the specific application and the desired surface finish and precision.
Q:What are the different specifications for steel round bars?
Steel round bars can be described using various specifications, including diameter, length, tolerance, and grade. The diameter determines the bar's size and is typically measured at its widest point. Diameters range from 1/4 inch to 12 inches, with different increments available. The length refers to the overall size of the round bar from end to end. Standard lengths are between 10 and 20 feet, but custom lengths can be obtained. When determining the quantity needed for a project, the length is an important factor to consider. Tolerance is a specification that allows for deviation from the specified diameter or length. It ensures that the round bar meets the required dimensions and can be effectively used. Tolerance values are usually expressed as plus or minus values, such as +/- 0.005 inches. The grade of steel used in round bars is also specified, indicating the material's quality and strength. Common grades include carbon steel, alloy steel, stainless steel, and tool steel. Each grade has unique properties suitable for different applications based on desired strength, corrosion resistance, and machinability. Surface finish and heat treatment may also be specified depending on the intended use of the round bars. These additional specifications ensure that the steel meets the necessary requirements for specific applications in various industries, such as construction and manufacturing.
