API 5L X56 / X60 Pipeline Steel Plate for Medium to High Pressure Transport

API 5L X56 / X60 Pipeline Steel Plate Overview

API 5L X56 steel plate and API 5L X60 steel plate are supplied for medium to high-pressure pipeline projects where higher yield strength and stable delivery are required.

These grades are typically specified when:

• X42 or X52 no longer meet pressure or design requirements
• Projects require higher strength without moving to X65 or above
• Cost control and weldability must be balanced

CJM supplies X56 and X60 steel plates with flexible thickness options, consistent mill sourcing, and full MTC documentation, supporting EPC contractors and infrastructure buyers in oil & gas, refinery, and industrial pipeline projects.

Plates can be delivered in PSL1 or PSL2, with cutting, testing, and export packing arranged according to project requirements, allowing buyers to move directly from technical confirmation to procurement.

Chemical Composition (API 5L X56 / X60)

Grade	C (Max)	Mn (Max)	P (Max)	S (Max)	Si (Max)
X56	0.26	1.40	0.030	0.030	0.45
X60	0.28	1.40	0.030	0.030	0.45

PSL2 grades are available with stricter chemical limits and controlled CEQ.

Mechanical Properties (API 5L X56 / X60)

Grade	Yield Strength (MPa)	Tensile Strength (MPa)	Elongation (%)
X56	≥ 386	490 – 660	≥ 21
X60	≥ 414	520 – 675	≥ 21

These properties ensure reliable performance under pressure variations and long-term cyclic loading in pipeline systems.
