EN 10210 refers to the European standard "Hot rolled structural steel bars, rods and sections -
Specifically, the chemical compositions specified in the EN 10210 standard mainly include carbon (C), silicon (Si), manganese (Mn), phosphorus (P), sulfur (S) and other elements, as well as some other alloying elements that may exist, Such as chromium (Cr), nickel (Ni), etc. In S355J2H seamless steel pipe, the chemical composition content (in weight percentage) is as follows:
| Carbon (C) | Silicon (Si) | Manganese(Mn) | Phosphorus (P) | Sulfur (S) | Chromium (Cr) | Nickel (Ni) |
| ≤0.22% | ≤0.55% | ≤1.60% | ≤0.025% | ≤0.020% | ≤0.25% |
≤0.50% |
When producing steel pipes according to the EN 10210 standard, common production methods include pipe making processes such as smelting, continuous casting and rolling. These processes ensure that the chemical composition, mechanical properties and dimensional tolerances of the steel meet standard requirements.
The characteristics of the EN 10210 standard are mainly reflected in the following aspects:
1. High strength: EN10210 has high strength and can withstand greater pressure and heavy loads, which makes it widely used in the fields of construction, engineering and machinery.
2. Good weldability: Good weldability makes the manufacturing and installation process of steel pipes more convenient, and also improves the performance and life of steel pipes.
3. Corrosion resistance: EN10210 standard seamless steel pipes are made of corrosion-resistant materials and can be used in harsh environments for a long time, reducing the frequency of maintenance and replacement and reducing usage costs.
4. High precision: This standard strictly controls the size and geometry of steel pipes, has high precision and stability, and can meet the needs of various complex structures and precision components.
The application scope of the EN 10210 standard is very wide, mainly covering the following aspects: in structural engineering such as buildings, pidges, and mechanical equipment. Used as pipes and connections in hydraulic systems. In the oil and gas industry, pipeline systems used to transport oil and gas. Heat exchanger and boiler field: used in heat exchangers and boilers to transport high-temperature fluids. Construction steel structure: used for construction steel structures, such as houses, civil engineering and other load-bearing structures.
