ASTM A53 Seamless Steel Pipe

ASTM A53 seamless steel pipe refers to the foreign standard steel pipe grade, that is, the American sign. A53-F corresponds to domestic q235 material, A53-A corresponds to domestic 10# material, and A53-B corresponds to domestic 20# material.

ASTM A53 (ASME SA53) carbon steel pipe is a specification that covers seamless and welded black and hot-dipped galvanized steel pipe in NPS 1/8″ to NPS 26.  

A53 Grade B Seamless is our most polar product under this specification and A53 pipe is commonly dual certified to A106 B Seamless pipe.

ASTM A53 Mechanical Properties:

	Grade A	Grade B
Tensile Strength, min., psi, (MPa)	48,000 (330)	60,000 (415)
Yield Strength, min., psi, (MPa)	30,000 (205)	35,000 (240)

ASTM A53 seamless steel pipe is intended for pressure and mechanical applications and is also acceptable for ordinary uses in steam, water, gas, and air lines.
