Product Description

Product Description

ASTM A106 is a widely acclaimed standard for seamless carbon steel pipes, renowned for its exceptional applicability in industrial sectors. Its remarkable performance under elevated temperatures makes it indispensable. The standard comprises three grades: A, B, and C; each is crafted with distinct chemical compositions and mechanical properties to cater to diverse application demands.
Application fields of seamless steel pipes under ASTM A106 standard:
Boiler and Power Plant: In the realm of boilers and power plants, ASTM A106 seamless steel pipes, notably A106 Gr. B, are indispensable. They ensure the seamless operation of equipment due to their outstanding thermal conductivity and resistance to heat.
Petroleum, Natural Gas, Chemical, and Power Industries: The SA-106Gr. C high-pressure boiler tubes (ASTM A106C) are primarily utilized in environments characterized by high temperatures and pressures, pivotal to the petroleum, natural gas, chemical, and power industries.
Industries such as Shipbuilding, Machinery Manufacturing, Automotive, Aviation, Aerospace, Energy, Geology, Construction, and Military: The versatility of ASTM A106 seamless steel pipes extends their use across a multitude of sectors including these robust industries.
Chemical Composition and Mechanical Properties:
Carbon Content: For Grade A, it does not surpass 0.25%; Grade B ranges between 0.18-0.25%; Grade C spans 0.25-0.35%. An increase in carbon content correlates with enhanced strength, though excessive carbon can lead to quenching and diminished toughness.
Manganese Content: Ranges approximately from 0.29 to 1.06%. This element refines grain size, fortifies ferrite, and amplifies both tensile and compressive strength, enhancing the pipe's structural integrity.
Silicon Content: Steadily maintained at approximately 0.10%, it plays a crucial role in the deoxidation and purification of molten steel, contributing to the overall quality of the pipes.
Tensile Strength and Yield Strength: Grade A exhibits a tensile strength not less than 330MPa, with a yield strength of 207MPa minimum; Grade B shows 415MPa and 240MPa; Grade C boasts 485MPa and 275MPa, respectively, underscoring the formidable strength across grades.
Elongation Rate: Typically required to exceed 30%, ensuring that the steel pipe effectively absorbs energy through deformation upon impact, thereby mitigating the risk of brittle fracture.
