Product Description
DIN 1615 St33 St37 St42 St34.2 St37.2 Round Structural Pipe Welded Circular Unalloyed Steel Tubes
Material Specification
DIN 1615 standard specifies the requirements for welded circular unalloyed steel tubes used for structural purposes. These pipes are commonly used in construction and engineering projects due to their strength, durability, and versatility. The standard covers various steel grades, including St33, St37, St42, St34.2, and St37.2, each offering distinct mechanical properties to suit different applications.
Key Features
- Versatility: Suitable for a wide range of structural applications.
- Durability: High resistance to wear and tear, ensuring long service life.
- Cost-Effective: Economical choice for structural projects.
- Weldability: Excellent welding properties, facilitating easy fabrication.
- Compliance: Meets international standards for structural steel pipes.
Chemical Composition
The chemical composition of these steel grades is crucial for determining their mechanical properties and suitability for specific applications. Below is a table presenting the typical chemical composition for these grades:
| Element | St33 (%) | St37 (%) | St42 (%) | St34.2 (%) | St37.2 (%) |
|---|---|---|---|---|---|
| C | ≤ 0.17 | ≤ 0.20 | ≤ 0.22 | ≤ 0.17 | ≤ 0.20 |
| Mn | ≤ 1.40 | ≤ 1.40 | ≤ 1.40 | ≤ 1.40 | ≤ 1.40 |
| P | ≤ 0.045 | ≤ 0.045 | ≤ 0.045 | ≤ 0.045 | ≤ 0.045 |
| S | ≤ 0.045 | ≤ 0.045 | ≤ 0.045 | ≤ 0.045 | ≤ 0.045 |
Mechanical Properties
The mechanical properties of these steel grades define their performance under various conditions. The table below summarizes the typical mechanical properties:
| Property | St33 | St37 | St42 | St34.2 | St37.2 |
|---|---|---|---|---|---|
| Yield Strength (MPa) | ≥ 185 | ≥ 235 | ≥ 275 | ≥ 185 | ≥ 235 |
| Tensile Strength (MPa) | 340-470 | 360-510 | 410-550 | 340-470 | 360-510 |
| Elongation (%) | ≥ 25 | ≥ 24 | ≥ 22 | ≥ 25 | ≥ 24 |
Steel Grade
The steel grades covered under DIN 1615 include:
- St33: Known for its excellent ductility and weldability.
- St37: Offers a good balance of strength and ductility.
- St42: Provides higher strength, suitable for more demanding applications.
- St34.2: Similar to St33 but with slight variations in mechanical properties.
- St37.2: An enhanced version of St37 with improved mechanical characteristics.
Application
