| High Light | Unalloyed Steel Round Structural Pipe ，DIN 1615 Round Structural Pipe ，Welded Circular Round Structural Pipe | ||
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.
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 |
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 |
The steel grades covered under DIN 1615 include:
These steel tubes are widely used in:
Depending on the specific requirements of a project, alternative grades may be considered:
A: manufacturer,also can do trading.
A: Generally speaking,it is 10-15 days if the goods are in stock,or it is 30-40 days if the goods are not in stock, it is according to quantity.
A: Yes, we could offer the sample for free charge but need pay the cost of freight.
A: Payment<=2000USD, 100% in advance. Payment>=2000USD, 30% T/T in advance ,balance before shippment.
