API 5L X42 is a high-strength, low-alloy steel grade used for manufacturing pipelines in the oil and gas industry. It offers excellent mechanical properties and durability, making it suitable for demanding applications in pipeline transportation systems.
API 5L X42 steel has a carefully controlled chemical composition to achieve its desired properties. For PSL2, the maximum carbon content is 0.24%, with manganese content up to 1.30%. The minimum yield strength is 290 MPa (42,100 psi), and the minimum tensile strength is 415 MPa (60,200 psi).
| Property | PSL1 | PSL2 |
|---|---|---|

| Tensile Strength (min) | 415 MPa (60,200 psi) | 415 MPa (60,200 psi) |
| Elongation (min) | 23% | 23% |
| Carbon Content (max) | 0.28% | 0.24% |
| Manganese Content (max) | 1.30% | 1.30% |
| Phosphorus Content (max) | 0.030% | 0.025% |
| Sulfur Content (max) | 0.030% | 0.015% |
API 5L X42 pipes can be manufactured using various processes:
API 5L X42 pipelines are widely used in:
Key advantages include high strength-to-weight ratio, excellent toughness, and good weldability.
Rigorous quality control measures are implemented during the manufacturing of API 5L X42 pipes, including:
PSL2 has stricter requirements for chemical composition, mechanical properties, and testing compared to PSL1. PSL2 is typically used for more critical applications.
API 5L X42 has lower yield and tensile strengths compared to X52 and X60. It offers a good balance of strength and weldability for less demanding applications.
Main applications include oil and gas transmission pipelines, water transportation systems, and petrochemical industry pipelines.
API 5L X42 pipes can be manufactured using seamless (hot rolling or cold drawing) or welded (ERW, LSAW, SSAW) processes.
Key advantages include high strength-to-weight ratio, excellent toughness, good weldability, and suitability for various pipeline applications.
