Product Description
DIN 17120 St37-2 St37-3 St44-2 St44-3 St52-3 Structural Steel Pipe Welded Circular Steel Tubes for Structural Steelwork
Material
DIN 17120 specifies the requirements for welded circular steel tubes used in structural applications. These tubes are commonly used in construction, machinery, and various engineering applications due to their excellent mechanical properties and weldability.
Specification
The standard outlines the specifications for different grades of structural steel pipes, including St37-2, St37-3, St44-2, St44-3, and St52-3. Each grade has specific mechanical and chemical properties that make them suitable for various applications.
Key Features
- Weldability: Excellent weldability for easy fabrication.
- Strength: High tensile strength suitable for structural applications.
- Versatility: Can be used in various environments and applications.
- Durability: Resistant to deformation under load.
Chemical Composition
The following table presents the typical chemical composition of the various steel grades specified in DIN 17120:
| Steel Grade | C (%) | Si (%) | Mn (%) | P (%) | S (%) | Fe (%) |
|---|---|---|---|---|---|---|
| St37-2 | 0.17 | 0.25 | 1.40 | 0.045 | 0.045 | Bal. |
| St37-3 | 0.17 | 0.25 | 1.40 | 0.045 | 0.045 | Bal. |
| St44-2 | 0.20 | 0.25 | 1.60 | 0.045 | 0.045 | Bal. |
| St44-3 | 0.20 | 0.25 | 1.60 | 0.045 | 0.045 | Bal. |
| St52-3 | 0.22 | 0.25 | 1.60 | 0.045 | 0.045 | Bal. |
Mechanical Properties
The mechanical properties of the various steel grades are summarized in the following table:
| Steel Grade | Yield Strength (MPa) | Tensile Strength (MPa) | Elongation (%) |
|---|---|---|---|
| St37-2 | 235 | 360-510 | 26 |
| St37-3 | 235 | 360-510 | 26 |
| St44-2 | 275 | 410-550 | 24 |
| St44-3 | 275 | 410-550 | 24 |
| St52-3 | 355 | 490-630 | 22 |
Steel Grade
The steel grades specified in DIN 17120 are categorized based on their yield strength and chemical composition. These grades are widely used in construction and engineering due to their favorable properties.
Application
Welded circular steel tubes made from these grades are used in various applications, including:
- Structural frameworks in buildings and bridges
- Machinery components
- Automotive structures
- Pipelines and pressure vessels
Possible Alternative Grades
While DIN 17120 grades are widely used, there are alternative grades that may be considered based on specific requirements:
- S235: A European standard equivalent with similar properties.
- S275: Another European standard grade with higher yield strength.
- S355: Offers higher strength and is suitable for more demanding applications.
