Product Description

Product Description

The ASTM A106 standard is a hallmark in the world of seamless carbon steel pipes, renowned for its adaptability in high-temperature industrial environments. This specification is elegantly categorized into three grades: A, B, and C, each distinguished by unique chemical compositions and mechanical strengths to cater to a variety of application needs.
Application fields of seamless steel pipes under ASTM A106 standard:
Boiler and Power Plant: Within the demanding sectors of boilers and power plants, ASTM A106 seamless steel pipes, particularly A106 Gr. B, stand as a testament to reliability. Their superior thermal conductivity and outstanding heat resistance ensure seamless functionality of critical equipment.
Petroleum, Natural Gas, Chemical, and Power Industries: For high-pressure boiler operations, SA-106Gr. C pipes (ASTM A106C) are indispensable. Their robustness makes them ideal for harsh high-temperature and high-pressure conditions prevalent in petroleum, natural gas, chemical, and power industries.
Industries such as Shipbuilding, Machinery Manufacturing, Automotive, Aviation, Aerospace, Energy, Geology, Construction, and Military: In these diverse sectors, ASTM A106 seamless steel pipes offer exceptional versatility and durability, ensuring superior performance across various demanding applications.
Chemical Composition and Mechanical Properties:
Carbon Content: Grade A maintains a maximum of 0.25%, Grade B ranges between 0.18-0.25%, and Grade C spans 0.25-0.35%. The incremental carbon content enhances strength, yet meticulous balance is key to preventing quench-induced brittleness.
Manganese Content: Ranging from 0.29-1.06%, manganese is pivotal in refining grain size, fortifying ferrite, and augmenting both tensile and compressive strength.
Silicon Content: Consistently around 0.10%, silicon plays a crucial role in deoxidizing and purifying molten steel, ensuring the integrity of the final product.
Tensile Strength and Yield Strength: For Grade A, tensile strength is no less than 330MPa and yield strength no less than 207MPa. Grade B boasts 415MPa and 240MPa, whereas Grade C excels with 485MPa and 275MPa, highlighting their superior performance.
Elongation Rate: A vital attribute, the elongation rate surpasses 30%, empowering the steel pipe to absorb energy through deformation during impacts, thereby averting sudden brittle fractures.
