Carbon steel API 5L X42 material properties

API 5L X42 material meets the API 5L steel pipe standard. API is the abbreviation of American Petroleum Institute, this standard is universal in the world, suitable for straight seam steel pipe, seamless steel pipe, spiral seam steel pipe. Carbon steel API 5L X42 material properties are as below.

Carbon steel API 5L X42 material properties - chemical composition:

Grade C Si Mn P S V Nb Ti
API 5L X42 PSL1 0.26   1.30 0.030 0.030 Nb + V + Ti≤0.15%
API 5L X42 PSL2 0.22 0.45 1.30 0.025 0.015 0.05 0.05 0.04

Carbon steel API 5L X42 material properties - mechanical properties:

Grade Yield Strength Tensile Strength
Mpa (Psi) Mpa (Psi)
API 5L X42 PSL1 290 (42100) 415 (60200)
API 5L X42 PSL2 290(42100) - 495(71800) 415(60200)- 760(110200)

Among API 5L X42 material properties, API 5L X42 yield strength is not less than 290 MPa. API 5L X42 material specification level is divided into API 5L X42 PSL1 and API 5L X42 PSL2. They have different standard technical requirements. API 5L X42 PSL2 has mandatory requirements for carbon equivalent, notch toughness, maximum yield strength, and maximum tensile strength.
