Product Description
DIN 1628 ST37.4 ST44.4 ST52.4 Electric Resistance Welded Pipe Non Alloy Welded Steel Tubes For Special Requests
Material
DIN 1628 specifies the requirements for electric resistance welded (ERW) non-alloy steel tubes. These tubes are primarily used in various applications requiring high strength and durability. The standard covers several grades, including ST37.4, ST44.4, and ST52.4, each with distinct mechanical properties and chemical compositions.
Specification
The specifications under DIN 1628 outline the dimensions, tolerances, and testing methods for the welded steel tubes. The standard ensures that the tubes meet specific quality and performance criteria suitable for various industrial applications.
Key Features
- Electric Resistance Welding: Ensures strong and uniform welds.
- Non-Alloy Steel: Provides good weldability and machinability.
- Versatile Applications: Suitable for structural, mechanical, and hydraulic applications.
- Customizable Sizes: Available in various diameters and wall thicknesses.
Chemical Composition
The following table summarizes the chemical composition of the steel grades specified in DIN 1628:
| Steel Grade | C (%) | Si (%) | Mn (%) | P (%) | S (%) |
|---|---|---|---|---|---|
| ST37.4 | 0.17 | 0.40 | 1.40 | 0.045 | 0.045 |
| ST44.4 | 0.20 | 0.40 | 1.60 | 0.045 | 0.045 |
| ST52.4 | 0.22 | 0.40 | 1.70 | 0.045 | 0.045 |
Mechanical Properties
The mechanical properties of the steel grades are critical for determining their suitability for specific applications. The following table outlines these properties:
| Steel Grade | Yield Strength (MPa) | Tensile Strength (MPa) | Elongation (%) |
|---|---|---|---|
| ST37.4 | 235 | 360-510 | 26 |
| ST44.4 | 275 | 400-550 | 24 |
| ST52.4 | 355 | 490-630 | 22 |
Steel Grade
- ST37.4: Commonly used for structural applications where moderate strength is required.
- ST44.4: Offers higher strength and is suitable for more demanding applications.
- ST52.4: Provides the highest strength among the three grades, ideal for heavy-duty applications.
Application
The DIN 1628 steel tubes are widely used in various industries, including:
- Construction: Structural components, scaffolding, and frames.
- Automotive: Chassis and body parts.
- Mechanical Engineering: Machine parts and components.
- Hydraulics: Pipes and tubes for fluid transport.
Possible Alternative Grades
While ST37.4, ST44.4, and ST52.4 are commonly used, there are alternative grades that may be suitable depending on the specific requirements:
- S235JR: A European standard grade with similar properties to ST37.4.
- S275JR: Comparable to ST44.4, offering higher yield strength.
- S355JR: Similar to ST52.4, providing enhanced mechanical properties.
