The EN 10025-2 standard specifies the chemical composition of structural steel, which includes elements such as carbon (C), silicon (Si), manganese (Mn), phosphorus (P), sulfur (S), and other alloys that may be included. element.
The EN 10025-2 standard defines the technical delivery conditions for structural steel, but does not directly specify the specific production methods. However, the production of structural steel typically follows a series of standard metallurgical processes and manufacturing processes.
For structural steel under the EN 10025-2 standard, the production method may include the following main steps: raw material preparation, smelting, refining, continuous casting, rolling, heat treatment, cutting and processing, testing and quality control.
The characteristics of EN 10025-2 are mainly reflected in the following aspects:
1. High strength: The channel steel in this standard is made of high-strength steel, and its tensile strength can reach more than 400MPa, which ensures that the steel can withstand large loads in various engineering applications.
2. Clear chemical composition and mechanical performance requirements: The EN 10025-2 standard specifies the chemical composition and mechanical performance requirements of steel in detail, including properties such as yield strength, tensile strength, elongation and impact toughness, ensuring the quality and performance of steel. The performance is stable and reliable.
3. High safety: Using steel materials that comply with EN 10025-2 standards can improve the safety of structural engineering. These steels have undergone rigorous testing and inspection to maintain structural stability and durability during use.
4. Unified specifications and dimensions: The steel materials of the EN 10025-2 standard have uniform specifications and dimensions and can be easily interchanged with other steel materials that comply with this standard, reducing the complexity in the engineering construction and equipment manufacturing processes.
5. Reliable quality: The EN 10025-2 standard requires that steel must meet strict chemical composition and mechanical performance requirements to ensure that the quality of the steel is reliable and can bear weight and withstand pressure stably for a long time.
The application scope of the EN 10025-2 standard is very wide, mainly covering construction, pidges, ships, boilers, metallurgy, energy and other fields. Specifically: In the construction field, EN 10025-2 standard steel is widely used in the frame structure of buildings, such as beams, columns, floor slabs, etc., bearing various loads and having good strength and durability. In pidge engineering, these steel materials also play an important role and are often used to manufacture the main structure and connecting parts of pidges, which bear the load of vehicles and pedestrians. In the field of shipbuilding, EN 10025-2 standard steel is used to manufacture structural components of the hull. In the field of boilers and metallurgy, these steels are used to make support structures for boilers and vessels that can withstand high temperatures and high pressure loads. In the energy field, EN 10025-2 standard steel is also used to manufacture the support structures of oil and gas pipelines to ensure the safety and reliability of the transportation process.
