| High Light | CK45 Honed Hydraulic Tube ，SRB Honed Tube ，Skived And Roller Burnished Tube | ||
Honed hydraulic tubes, particularly those that are skived and roller burnished (SRB), are essential components in hydraulic equipment. These tubes, such as the CK45, C20, Q355B, E355(ST52), and SAE1026, are known for their impeccable surface finishes and tightly controlled dimensional tolerances. They are ideal for applications that require high pressure and minimal friction. These tubes are manufactured to meet rigorous specifications, ensuring their reliability and durability in demanding environments.
Here's a tabular representation of the chemical compositions for these steel grades:
| Grade | C (%) | Mn (%) | Si (%) | P (%) | S (%) | Cr (%) | Mo (%) | Ni (%) |
|---|---|---|---|---|---|---|---|---|
| CK45 | 0.42-0.50 | 0.50-0.80 | 0.10-0.40 | ≤0.040 | ≤0.040 | - | - | - |
| C20 | 0.17-0.23 | 0.30-0.60 | ≤0.40 | ≤0.045 | ≤0.045 | - | - | - |
| Q355B | ≤0.20 | 1.0-1.7 | ≤0.55 | ≤0.030 | ≤0.030 | ≤0.30 | ≤0.10 | ≤0.70 |
| E355(ST52) | ≤0.22 | 1.30-1.60 | ≤0.55 | ≤0.025 | ≤0.025 | - | - | - |
| SAE1026 | 0.22-0.28 | 0.60-0.90 | 0.15-0.35 | ≤0.040 | ≤0.050 | - | - | - |
The mechanical properties of these materials are critical for their performance in hydraulic systems. Below is a summary:
| Grade | Yield Strength (MPa) | Tensile Strength (MPa) | Elongation (%) | Hardness (HB) |
|---|---|---|---|---|
| CK45 | ≥310 | 570-700 | ≥16 | 156-207 |
| C20 | 290 | 440-580 | ≥23 | - |
| Q355B | ≥345 | 470-630 | ≥21 | - |
| E355(ST52) | ≥355 | 490-630 | ≥20 | 160-210 |
| SAE1026 | ≥275 | 440-670 | ≥25 | 163-220 |
To assist in global applications, here is a comparison of these materials to various international standards.
