Product Description

Product Description

The ASTM A106 seamless carbon steel pipes are a hallmark of industrial excellence, renowned for their robustness in high-temperature environments. This standard is segmented into three distinguished grades: A, B, and C, each crafted with unique chemical compositions and mechanical properties to adeptly fulfill diverse industrial applications and requirements.
Diverse Application Scope of ASTM A106 Seamless Steel Pipes:
Boiler and Power Plant Applications: Embrace the reliability of ASTM A106 seamless steel pipes within boilers and power plants. Specifically, A106 Gr. B pipes excel in these settings, delivering unparalleled performance with superior thermal conductivity and exceptional heat resistance, ensuring seamless equipment operation.
Petroleum, Natural Gas, Chemical, and Power Sector Applications: The SA-106Gr. C high-pressure boiler tubes (ASTM A106C) stand as a testament to engineering strength, tailored for high-temperature and high-pressure environments typical in the petroleum, natural gas, chemical, and power industries.
Extensive Industry Applications: From shipbuilding to machinery manufacturing, automotive to aerospace, and across sectors like energy, geology, construction, and military, ASTM A106 seamless steel pipes are indispensable, offering unmatched versatility and reliability.
Key Chemical and Mechanical Attributes:
Carbon Content Insights: Grade A features a carbon cap of 0.25%, Grade B ranges from 0.18-0.25%, and Grade C escalates from 0.25-0.35%. As carbon content increases, so does the strength, though a higher carbon content can enhance quench tendency, impacting toughness.
Manganese Composition: Spanning approximately 0.29-1.06%, manganese plays a crucial role in refining grain size, fortifying ferrite, and amplifying tensile and compressive strength.
Silicon Content: Maintained at an optimal 0.10%, silicon is essential for the deoxidation and purification process of molten steel, ensuring premium quality.
Strength Characteristics: Grade A boasts a tensile strength of no less than 330MPa, with a yield strength not under 207MPa. Meanwhile, Grade B achieves 415MPa and 240MPa respectively, and Grade C reaches impressive thresholds of 485MPa and 275MPa.
Elongation Properties: An elongation rate exceeding 30% is generally mandated, ensuring that the steel pipes can effectively absorb and dissipate energy upon impact, thereby preventing brittle fractures.
