| E355 | 0.20 | 0.10 | 1.60 | 0.025 | 0.025 | - | - | - |
| 1.4571 | 0.07 | 1.00 | 1.00 | 0.045 | 0.015 | 16.00 | 10.00 | 2.50 |
Mechanical Properties
| Steel Grade | Yield Strength (MPa) | Tensile Strength (MPa) | Elongation (%) | Hardness (HB) |
| E235 | 235 | 360-510 | 26 | 120 |
| E355 | 355 | 490-630 | 22 | 140 |
| 1.4571 | 210 | 500-700 | 40 | 160 |
Steel Grade
- E235: A low carbon steel grade with good weldability and machinability, commonly used in structural applications.
- E355: A higher carbon content steel that offers improved strength and is suitable for higher pressure applications.
- 1.4571: Austenitic stainless steel known for its excellent corrosion resistance, particularly in aggressive environments.
Application
These seamless precision steel tubes are widely used in hydraulic systems for:
- Industrial Machinery: Hydraulic presses, lifts, and other machinery requiring high-pressure fluid transfer.
- Automotive Systems: Brake lines, power steering, and other hydraulic components.
- Construction Equipment: Excavators, loaders, and other heavy machinery.
- Marine Applications: Hydraulic systems in ships and offshore platforms.
Possible Alternative Grades
- S235JR: A general structural steel grade with similar properties to E235.
- S355J2: A structural steel grade with higher strength compared to E355.
- 1.4401 (AISI 316): Another stainless steel alternative with excellent corrosion resistance for more demanding environments.
