DIN 2448 is a standard that specifies the requirements for seamless steel pipes and tubes used in mechanical manufacturing. The standard covers various grades, including ST37, ST44, and ST52, which are commonly used in engineering applications due to their excellent mechanical properties and versatility.
The seamless tubes and pipes under DIN 2448 are primarily made from carbon steel. The specifications ensure that the products meet the necessary mechanical and chemical properties for various applications.
The following table presents the typical chemical composition for the steel grades ST37, ST44, and ST52 as per DIN 2448:
| Steel Grade | C (%) | Si (%) | Mn (%) | P (%) | S (%) | Cr (%) | Ni (%) | Mo (%) |
|---|---|---|---|---|---|---|---|---|
| ST37 | 0.10 | 0.15 | 0.60 | 0.04 | 0.05 | 0.25 | 0.25 | 0.10 |
| ST44 | 0.20 | 0.15 | 0.80 | 0.04 | 0.05 | 0.25 | 0.25 | 0.10 |
| ST52 | 0.22 | 0.15 | 1.20 | 0.04 | 0.05 | 0.25 | 0.25 | 0.10 |
The mechanical properties of the steel grades ST37, ST44, and ST52 are summarized in the following table:
| Steel Grade | Yield Strength (N/mm²) | Tensile Strength (N/mm²) | Elongation (%) | Hardness (HB) |
|---|---|---|---|---|
| ST37 | 235 | 360-510 | 26 | 120-160 |
| ST44 | 275 | 410-550 | 24 | 130-170 |
| ST52 | 355 | 490-630 | 22 | 140-180 |
The seamless tubes and pipes conforming to DIN 2448 are widely used in various industries, including:
