DIN 2393-2 specifies the technical delivery conditions for welded precision steel tubes made from carbon steel. These tubes are primarily used in the automotive industry due to their excellent mechanical properties and precision. The materials covered under this standard include E235, ST37.2, ST52.3, STKM11, and STKM12, which are known for their strength, ductility, and weldability.
The cold drawn welded tubes are manufactured using Electric Resistance Welding (ERW) and are further processed to achieve precision dimensions and enhanced mechanical properties. These tubes are available in various dimensions and can be customized according to specific requirements.
The chemical composition of these steel grades is crucial for their performance. Below is a table presenting the typical chemical composition:
| Element | E235 (%) | ST37.2 (%) | ST52.3 (%) | STKM11 (%) | STKM12 (%) |
|---|---|---|---|---|---|
| C | ≤ 0.17 | ≤ 0.17 | ≤ 0.22 | ≤ 0.12 | ≤ 0.20 |
| Si | ≤ 0.35 | ≤ 0.35 | ≤ 0.55 | ≤ 0.35 | ≤ 0.35 |
| Mn | ≤ 1.20 | ≤ 1.20 | ≤ 1.60 | ≤ 0.60 | ≤ 0.60 |
| P | ≤ 0.025 | ≤ 0.025 | ≤ 0.025 | ≤ 0.030 | ≤ 0.030 |
| S | ≤ 0.025 | ≤ 0.025 | ≤ 0.025 | ≤ 0.030 | ≤ 0.030 |
The mechanical properties of these tubes determine their suitability for various applications. The table below outlines the typical mechanical properties:
| Property | E235 | ST37.2 | ST52.3 | STKM11 | STKM12 |
|---|---|---|---|---|---|
| Yield Strength (MPa) | ≥ 235 | ≥ 235 | ≥ 355 | ≥ 245 | ≥ 275 |
| Tensile Strength (MPa) | 340-480 | 340-480 | 490-630 | 370-510 | 410-550 |
| Elongation (%) | ≥ 25 | ≥ 25 | ≥ 22 | ≥ 30 | ≥ 25 |
The steel grades covered under DIN 2393-2 include:
These precision steel tubes are widely used in the automotive industry for:
Depending on specific requirements, 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.
