Mechanical Properties
| Steel Grade | Yield Strength (MPa) | Tensile Strength (MPa) | Elongation (%) | Hardness (HB) |
| ST37 | 235 | 360-510 | 26 | 120-160 |
| ST45 | 245 | 370-540 | 24 | 130-170 |
| ST52 | 355 | 490-630 | 22 | 150-190 |
Steel Grade
- ST37: Low carbon steel with good weldability and machinability.
- ST45: Medium carbon steel offering higher strength and hardness.
- ST52: High carbon steel with excellent tensile strength and toughness.
Application
These seamless precision steel tubes are used in a variety of applications, including:
- Structural components in construction and engineering.
- Hydraulic systems and machinery.
- Automotive and transportation industries.
- Oil and gas pipelines.
- General mechanical engineering.
Possible Alternative Grades
- S235: A structural steel grade with similar properties to ST37.
- S355: A higher strength structural steel that can be used in place of ST52.
- EN 10210: A European standard for hot-finished structural hollow sections, which may serve as an alternative.
