What is P30 Steel Rail? Basic specifications
P30 steel rail is a light steel rail that meets the Chinese standard. It is similar to other light rails such as P18, P24, etc., and is often used for small to medium-sized crane or gantry cranes, or in mechanical, railway, and construction industries.
P30 rail is named after its weight per meter. Thus, one meter of P30 rail weighs 30.1 kg.
Material: P30 rail is made of Q235/55Q steel. This is a common alloy steel used in railway tracks due to its strength and durability. Q235/55Q steel has an average carbon content of about 0.83-0.93%. Its high manganese content of about 1.4-1.8% helps to improve the strength and ductility of the steel.
Length: The length of each rail section can vary from 6 to 12 meters. The length of the rail is selected based on the requirements of a specific project.
The dimensions of the P30 steel rail are specified in the GB 11264-89 standard. Specifically, the dimensions are as follows:
- Head width: 60.33 mm
- Bottom width: 107.95 mm
- Rail height: 107.95 mm
- Web thickness: 12.3 mm
Chemical composition:
The chemical composition of the P30 steel rail is specified in the GB 11264-89 standard. Specifically, the chemical composition of the P30 is as follows:
| Component | Content |
|---|---|
| Carbon (C) | 0.83-0.93% |
| Manganese (Mn) | 1.4-1.8% |
| Silicon (Si) | 0.2-0.4% |
| Phosphorus (P) | 0.04% |
| Sulfur (S) | 0.05% |
Mechanical properties:
Yield strength: 235 Mpa
Tensile strength: 370-500 Mpa
Elongation: 26%
Applications
P30 steel rail is widely used in various industries and construction, specifically as follows:
- Railway industry: Used for railway tracks for trains and locomotives.
- Construction industry: Used for crane tracks in factories and plants.
- Mechanical industry: Used as load-bearing parts in machinery and equipment.
Precautions when using P30 steel rail:
When using P30 rail, it is important to note the following:
- The rail must be stored in a dry, cool place away from contact with rain or dirty water.
- In addition, it must be regularly inspected to ensure quality and safety.
