API Spec 5L PSL2 X65 (L450) Pipeline Steel Plate
When transporting acidic media, pipeline steel must resist hydrogen embrittlement, and the hydrogen content is required to be less than 0.0002%; for inclusions in the steel, the maximum diameter must be less than 100 μm, and the shape of the oxide must be controlled to eliminate the influence of strip-shaped sulfide inclusions.
