Product Description

Product Description

The ASTM A106 standard sets the gold standard for seamless carbon steel pipes, prized across industries for its stellar performance in high-temperature environments. This sought-after standard is meticulously divided into three distinct grades: A, B, and C, each crafted with unique chemical compositions and mechanical properties to satisfy a diverse array of application needs.
Application fields of seamless steel pipes under ASTM A106 standard:
Boiler and Power Plant: Embrace the reliability of ASTM A106 seamless steel pipes, a staple in boilers and power plants. Especially favored are the A106 Gr. B seamless steel pipes, renowned for their exceptional thermal conductivity and heat resistance, ensuring seamless operation of high-demand equipment.
Petroleum, Natural Gas, Chemical, and Power Industries: SA-106 Gr. C high-pressure boiler tubes (ASTM A106C) stand out for high-temperature and high-pressure environments. Essential for the petroleum, natural gas, chemical, and power sectors, these pipes ensure peak performance under intense working conditions.
Diverse Industries: ASTM A106 seamless steel pipes find widespread application in a myriad of sectors including shipbuilding, machinery manufacturing, automotive, aviation, aerospace, energy, geology, construction, and military, underscoring their versatility and reliability.
Chemical composition and mechanical properties:
Carbon Content: Precision is key, with Grade A capped at 0.25%, Grade B ranging from 0.18-0.25%, and Grade C from 0.25-0.35%. As carbon content increases, so does strength, yet caution is necessary as too much carbon can enhance quenching tendencies and compromise toughness.
Manganese Content: Spanning approximately 0.29-1.06%, manganese is a critical element that refines grain size, fortifies ferrite, and boosts tensile and compressive strength, adding robustness to the pipes.
Silicon Content: Maintained at around 0.10%, silicon is primarily responsible for the deoxidation and purification of molten steel, ensuring the highest quality is achieved.
Tensile and Yield Strength: Grade A boasts a tensile strength not less than 330MPa and yield strength above 207MPa. For Grade B, values reach 415MPa and 240MPa respectively, while Grade C excels with 485MPa and 275MPa, showcasing their structural fortitude.
Elongation Rate: A superb elongation rate exceeding 30% is demanded to ensure resilience, allowing the steel pipe to absorb energy through deformation upon impact, thus preventing brittle fractures.
