Product Description

ASTM 106

ASTMA106 seamless pressure pipe(also known as ASMESA106 pipe) is commonly used in the construction of oil and gas refineries, power plants, petrochemical plants, boilers, and ships where the piping must transport fluids and gases that exhibit higher temperatures and pressure levels.ASTM A106pipe includes three grades, A106GrA, A106GrB, and A106GrC.

ASTM A106 Chemical composition:

Steel Grade	C, max.%	Mn%	P, max	S, max	Si, min	Cr, max	Cu, max	Mo, max	Ni, max	V, max
Grade A	0.25	0.27 - 0.93	0.035	0.035	0.10	0.40	0.40	0.15	0.40	0.08
Grade B	0.30	0.29 - 1.06	0.035	0.035	0.10	0.40	0.40	0.15	0.40	0.08
Grade C	0.35	0.29 - 1.06	0.035	0.035	0.10	0.40	0.40	0.15	0.40	0.08

ASTM A106 Mechanical Property:

Grade	Tenssile Test MPa or N/mm2		Remarks (Similar to JIS)
Grade	MIn. Yield Point	Tensile Strength	Remarks (Similar to JIS)
Gr A	205	330Min	(STPG370)
Gr B	240	415Min	(STPG410)
Gr C	275	485Min	(STPG480)

ASTM A106 Seamless Pressure Pipe (also known as ASME SA106 pipe) covers seamless carbon steel nominal wall pipe for high-temperature service. Suitable for bending, flanging and similar forming operations.

Process

Killed steel, with primary melting process being open-hearth, basic-oxygen, or electric-furnace, possibly combined with separate degassing or refining.

Steel cast in ingots or strand cast is permissible.

Hot-finished pipe need not be heat treated.

Cold-drawn pipe shall be heat treated after the final cold draw pass.
