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.
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.
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. |
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 |
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.
Welded circular steel tubes made from these grades are used in various applications, including:
While DIN 17120 grades are widely used, there are alternative grades that may be considered based on specific requirements:
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.
