Product Description
GB 8713 is a standard that specifies the technical requirements, dimensions, and tolerances of precision inner diameter seamless steel tubes used for hydraulic and pneumatic cylinders. These tubes are used in applications where high accuracy and smooth surface finish are required. In this article, we will discuss the material, specification, chemical composition, mechanical properties, steel grade, and application of GB 8713 steel tubes.
GB 8713 precision inner diameter seamless steel tubes are made of high-quality carbon structural steel and alloy structural steel. The materials used for these tubes should be consistent with the relevant national standards.
The specification of GB 8713 steel tubes is as follows:
The chemical composition of GB 8713 steel tubes is shown in the following table:
| Material | C | Si | Mn | P | S |
|---|---|---|---|---|---|
| 10 | 0.07-0.13 | 0.17-0.37 | 0.35-0.65 | ≤0.035 | ≤0.035 |
| 20 | 0.17-0.24 | 0.17-0.37 | 0.35-0.65 | ≤0.035 | ≤0.035 |
| 35 | 0.32-0.39 | 0.17-0.37 | 0.50-0.80 | ≤0.035 | ≤0.035 |
| 45 | 0.42-0.50 | 0.17-0.37 | 0.50-0.80 | ≤0.035 | ≤0.035 |
| Q345B | 0.12-0.20 | 0.20-0.55 | 1.20-1.60 | ≤0.035 | ≤0.035 |
The mechanical properties of GB 8713 steel tubes vary depending on the steel grade. The following table shows the mechanical properties of different steel grades:
| Steel Grade | Tensile Strength (Mpa) | Yield Strength (Mpa) | Elongation (%) | Hardness (HB) |
|---|---|---|---|---|
| 10 | ≥335 | ≥205 | ≥24 | ≤100 |
| 20 | ≥410 | ≥245 | ≥20 | ≤100 |
| 35 | ≥510 | ≥305 | ≥17 | ≤100 |
| 45 | ≥590 | ≥335 | ≥14 | ≤100 |
| Q345B | ≥490 | ≥345 | ≥21 | ≤187 |
The steel grade of GB 8713 steel tubes is indicated by the grade number, which represents the minimum yield strength of the steel. The commonly used steel grades are 10, 20, 35, 45, and Q345B.
GB 8713 precision inner diameter seamless steel tubes are mainly used in hydraulic and pneumatic cylinders, as well as in the manufacturing of machinery, automobiles, and other mechanical components that require high precision and smooth surface
