Product Description

Product Description

ASTM A106 is a prestigious standard in the realm of seamless carbon steel pipes, celebrated for its versatility and reliability in the industrial sector. Especially renowned for its superb performance in high-temperature conditions, this standard is meticulously categorized into three distinct levels: A, B, and C. Each level is crafted with unique chemical compositions and mechanical properties, tailored to fulfill diverse application needs and ensure optimal functionality.
Prime Application Domains of ASTM A106 Seamless Steel Pipes:
Boilers and Power Plants: The ASTM A106 seamless steel pipes, particularly the A106 Gr. B variant, are indispensable in boilers and power plants. Their exceptional thermal conductivity and heat resistance are pivotal for sustaining seamless operation and high efficiency of the equipment.
Petroleum, Natural Gas, Chemical, and Power Industries: The SA-106Gr. C high-pressure boiler tubes (ASTM A106C) are expertly engineered for high-temperature and high-pressure scenarios in these critical industries. They are pivotal for efficient operation in demanding environments such as petroleum, natural gas, chemical, and power sectors.
Diverse Industries: From shipbuilding to machinery manufacturing, automotive to aviation, and aerospace to energy-ASTM A106 seamless steel pipes are integral across a broad spectrum of industries. Their robust design supports operations in geology, construction, and military sectors, highlighting their adaptability and reliability.
Chemical Composition and Mechanical Properties:
Carbon Content: For Grade A, carbon content is capped at 0.25%, while Grade B ranges from 0.18-0.25%, and Grade C spans 0.25-0.35%. As carbon content ascends, strength concurrently amplifies, though an overly high carbon presence may exacerbate quenching risks and impact toughness.
Manganese Content: Ranging between 0.29-1.06%, manganese adeptly refines grain size and fortifies ferrite, thereby enhancing both tensile and compressive strength to support rigorous applications.
Silicon Content: Kept consistent at approximately 0.10%, silicon plays a critical role in the deoxidation and purification of molten steel, ensuring quality and purity in production.
Tensile and Yield Strength: Grade A boasts a minimum tensile strength of 330MPa and yield strength of 207MPa; Grade B offers 415MPa and 240MPa respectively; while Grade C delivers impressive figures of 485MPa and 275MPa, ensuring durability and resilience.
Elongation Rate: It is imperative that the elongation rate surpasses 30%, allowing the steel pipe to absorb energy through deformation during impacts, thus preventing brittle fractures and enhancing safety.
