- High Strength: Suitable for high-pressure applications.
- Versatility: Applicable in various drilling and production environments.
Chemical Composition
The following table outlines the typical chemical composition of the API 5CT grades:
| Grade | C (%) | Mn (%) | P (%) | S (%) | Cr (%) | Ni (%) | Mo (%) |
|---|---|---|---|---|---|---|---|
| H40 | 0.26 | 0.90 | 0.020 | 0.010 | 0.30 | 0.30 | 0.10 |
| J55 | 0.26 | 0.90 | 0.020 | 0.010 | 0.30 | 0.30 | 0.10 |
| K55 | 0.26 | 0.90 | 0.020 | 0.010 | 0.30 | 0.30 | 0.10 |
| N80 | 0.30 | 1.20 | 0.020 | 0.010 | 0.30 | 0.30 | 0.10 |
| C110 | 0.30 | 1.20 | 0.020 | 0.010 | 0.30 | 0.30 | 0.10 |
Mechanical Properties
The following table summarizes the mechanical properties of the API 5CT grades:
| Grade | Yield Strength (MPa) | Tensile Strength (MPa) | Elongation (%) |
|---|---|---|---|
| H40 | 241 | 379 | 20 |
| J55 | 379 | 517 | 20 |
| K55 | 379 | 517 | 20 |
| N80 | 517 | 655 | 16 |
| C110 | 758 | 862 | 12 |
Steel Grade
The steel grades H40, J55, K55, N80, and C110 are categorized based on their yield strength and tensile strength, making them suitable for various applications in the oil and gas industry.
Application
These seamless steel tubes are primarily used in:
- Oil and gas drilling
- Well casing
- Production tubing
