Product Description

Product Description

The ASTM A106 seamless carbon steel pipe is esteemed in the industrial realm for its robust adaptability, especially under elevated temperatures. This standard is categorized into three distinct grades: A, B, and C, each offering unique chemical compositions and mechanical properties tailored to diverse application demands.
Application fields of seamless steel pipes under ASTM A106 standard:
Boiler and power plant: Within boiler and power plant settings, ASTM A106 seamless steel pipes, particularly the A106 Gr. B variant, are pivotal. Their superior thermal conductivity and resistance to heat ensure seamless equipment operation, upholding the highest standards of performance.
Petroleum, natural gas, chemical, and power industries: SA-106Gr. C pipes are the backbone in high-pressure, high-temperature environments within the petroleum, natural gas, chemical, and power sectors, demonstrating unparalleled durability and reliability.
Industries such as shipbuilding, machinery manufacturing, automotive, aviation, aerospace, energy, geology, construction, and military: The extensive reach of ASTM A106 seamless steel pipes spans these industries, underscoring their versatility and indispensability.
Chemical composition and mechanical properties:
Carbon content: Grade distinctions are crucial: Grade A up to 0.25%, Grade B from 0.18-0.25%, and Grade C from 0.25-0.35%. This progressive increase in carbon content correlates with enhanced strength, while maintaining a balance to prevent brittleness and ensure toughness.
Manganese content: Ranging between 0.29-1.06%, manganese plays a vital role in grain refinement, strengthening ferrite, and boosting tensile and compressive resilience.
Silicon content: Held at approximately 0.10%, silicon's primary role is in the deoxidation and purification of molten steel, optimizing quality and composition.
Tensile strength and yield strength: For Grade A, tensile strength is a minimum of 330MPa, and yield strength no less than 207MPa; Grade B achieves 415MPa and 240MPa respectively; Grade C excels with 485MPa and 275MPa.
Elongation rate: Exceeding 30%, the elongation rate is pivotal for energy absorption through deformation under impact, preventing brittle fractures and ensuring resilience.
