EN10025 St.52 Seamless Steel Pipe

ST52 seamless pipe is a type of seamless steel pipe made of ST52 steel, which belongs to the European standard of low-alloy high-strength structural steel. ST indicates the strength characteristics of the steel, and 52 indicates that its minimum tensile strength is approximately 520 MPa.

As standard EN10025 DIN17100

Chemical Composition:
- Carbon (C): ≤0.22%
- Silicon (Si):  ≤0.55%
- Manganese (Mn):  ≤1.60%
- Phosphorus (P): ≤0.035%
- Sulfur (S): ≤0.035%
Mechanical Properties:
- Tensile strength: 490MPa-630MPa
- Yield strength: ≥355MPa
