Stainless steel round steel belongs to the category of long materials and also to the category of rods. The so-called stainless steel round steel refers to long materials with a uniform circular cross-section, generally about four meters long. It can be divided into light circles and black bars. The so-called light circle refers to a smooth surface that has undergone quasi rolling treatment; The so-called black rod refers to a surface that is black and coarse, directly hot-rolled.
The difference between round steel and other steel bars:
1. The appearance is different. Round steel has a smooth and round shape, without lines or ribs, while other steel bars have grooves or ribs on the surface, resulting in a low bonding force between round steel and concrete, while other steel bars have a high bonding force with concrete.
2. The composition is different. Round steel (first grade steel) belongs to ordinary low-carbon steel, while other steel bars are mostly alloy steel.
3. The strength is different, with round steel having lower strength and other steel having higher strength. That is, round steel with the same diameter can withstand less tensile force compared to other steel bars, but its plasticity is stronger. That is, round steel has greater deformation before being pulled apart, while other steel bars have much smaller deformation before being pulled apart.
Stainless steel round steel has broad application prospects and is widely used in hardware kitchenware, shipbuilding, petrochemicals, machinery, medicine, food, electricity, energy, aerospace and other fields.

- Q: Are steel round bars corrosion resistant?
- Steel round bars are not inherently resistant to corrosion. This is because steel is mainly composed of iron, and iron tends to rust when it comes into contact with moisture and oxygen. Nevertheless, there are specific types of steel that have been engineered to resist corrosion. These types, including stainless steel, consist of added alloying elements such as chromium and nickel. These elements create a protective layer on the surface of the steel, which prevents rust and corrosion. Therefore, although standard steel round bars lack corrosion resistance, stainless steel round bars offer a corrosion-resistant alternative.
- Q: How do you identify the grade of a steel round bar?
- There are several ways to determine the grade of a steel round bar. First, examining the markings or labels on the bar itself can provide valuable information. Manufacturers often imprint or etch the grade directly onto the bar's surface. These markings usually include details like the grade designation (e.g., 304, 316, 4140), which represents the specific alloy composition, and may also include additional information such as the heat or lot number. Another method involves consulting the mill test certificate (MTC) that comes with the steel round bar. The MTC provides extensive information about the composition, mechanical properties, and other relevant specifications of the material. Typically, the steel mill or supplier issues the MTC, and it can be requested at the time of purchase. Additionally, the grade of a steel round bar can be determined through visual inspection and physical testing. Visual inspection entails examining the bar's appearance, texture, and color. Different grades of steel exhibit distinct characteristics, such as a glossy or matte finish, specific surface treatments, or variations in color due to varying alloying elements. Physical testing methods, such as tensile or hardness testing, can further confirm the steel grade. These tests measure the material's mechanical properties, including its strength, ductility, and hardness. By comparing the test results with established standards and specifications for different steel grades, it is possible to identify the grade of the round bar. In conclusion, to ascertain the grade of a steel round bar, one can inspect the markings, refer to the mill test certificate, visually assess the bar, and conduct physical tests to evaluate its mechanical properties.
- Q: Can steel round bars be threaded?
- Yes, steel round bars can be threaded. Threading refers to the process of cutting threads onto the surface of a cylindrical object, such as a steel round bar, to create a screw-like shape.
