DIN 1630 is a standard that specifies the requirements for non-alloy precision steel tubes used in hydraulic cylinders. The tubes are designed to withstand high pressure and provide excellent performance in various applications. This article discusses the material specifications, key features, chemical composition, mechanical properties, steel grades, applications, and possible alternative grades of these high-performance tubes.
The DIN 1630 standard covers non-alloy precision steel tubes, specifically designed for hydraulic applications. The materials used in these tubes are characterized by their high strength, durability, and resistance to deformation under pressure.
The specifications for DIN 1630 tubes include dimensions, tolerances, and surface quality. These tubes are typically produced in various diameters and wall thicknesses to meet specific application requirements.
| Steel Grade | C (%) | Si (%) | Mn (%) | P (%) | S (%) | Cr (%) | Ni (%) | Mo (%) |
|---|---|---|---|---|---|---|---|---|
| ST37.4 | 0.17 | 0.15 | 1.20 | 0.045 | 0.045 | - | - | - |
| ST44.4 | 0.20 | 0.15 | 1.40 | 0.045 | 0.045 | - | - | - |
| ST52.4 | 0.22 | 0.15 | 1.60 | 0.045 | 0.045 | 0.30 | 0.30 | 0.10 |
| Steel Grade | Yield Strength (MPa) | Tensile Strength (MPa) | Elongation (%) | Hardness (HB) |
|---|---|---|---|---|
| ST37.4 | 235 | 360-510 | 26 | 120-160 |
| ST44.4 | 275 | 430-580 | 24 | 140-180 |
| ST52.4 | 355 | 490-630 | 22 | 160-200 |
The primary steel grades covered under DIN 1630 are:
DIN 1630 precision steel tubes are widely used in:
While DIN 1630 grades are widely used, there are alternative grades that may be considered based on specific requirements:
