ST52 Seamless Steel Pipe is a high-strength, low-alloy structural steel pipe widely used in industrial and mechanical applications. The designation "ST52" follows the European standard (EN/DIN), where "ST" stands for structural steel, and "52" indicates the minimum yield strength of 355 *** (approximately 52,000 psi).
Key Features:
1. Material Composition:
- ST52 steel is a non-alloy quality steel with a carbon content of ¡Ü0.22% and additions of manganese, silicon, and trace elements to enhance strength and weldability.
2. Mechanical Properties:
- Yield Strength: ¡Ý355 ***
- Tensile Strength: 490¨C630 ***
- Elongation: ¡Ý21% (ensures good ductility)
- High i***ct resistance, even at low temperatures.
3. Manufacturing Process:
- Produced via hot-rolled or cold-drawn seamless processes, ensuring uniform wall thickness, no welds, and superior pressure resistance.
4. Applications:
- Ideal for high-stress environments such as:
- Structural frameworks in construction and heavy machinery.
- Hydraulic systems and pipelines for oil, gas, and chemical industries.
- Automotive components and mechanical parts requiring durability.
5. Advantages:
- Excellent load-bearing capacity and fatigue resistance.
- Good machinability and weldability (pre/post-heat treatment may be required).
- Corrosion resistance can be enhanced with coatings or galvanization.
6. Standards Compliance:
- Conforms to EN 10297-1, DIN 17100, and other international specifications.
This type of pipe is favored for its reliability in demanding conditions, combining strength, flexibility, and cost-effectiveness. Let me know if you need further technical ***ails |
