Product Description

Product Description

ASTM A106 is a highly regarded standard for seamless carbon steel pipes, known for its exceptional reliability in the industrial sector. These pipes excel under high-temperature conditions, making them a top choice for demanding environments. The standard is categorized into three distinct levels: A, B, and C. Each level is meticulously crafted with unique chemical compositions and mechanical properties to cater to varying application needs.
Application fields of seamless steel pipes under ASTM A106 standard:
Boiler and Power Plant: ASTM A106 seamless steel pipes are indispensable in boiler and power plant applications. Notably, A106 Gr. B seamless steel pipes are famed for their high thermal conductivity and remarkable heat resistance, ensuring seamless operation of equipment even under intense conditions.
Petroleum, Natural Gas, Chemical, and Power Industries: SA-106Gr. C high-pressure boiler tubes (ASTM A106C) prove invaluable in high-temperature and high-pressure environments across these sectors. Their robust design is tailored for the rigorous demands of the petroleum, natural gas, chemical, and power industries.
ASTM A106 seamless steel pipes are also extensively employed in industries such as shipbuilding, machinery manufacturing, automotive, aviation, aerospace, energy, geology, construction, and military applications, providing unparalleled reliability and performance.
Chemical composition and mechanical properties:
Carbon Content: Grade A caps its carbon content at 0.25%, while Grade B ranges between 0.18-0.25%, and Grade C spans 0.25-0.35%. As carbon content increases, so does strength, although excessive carbon can elevate quenching tendencies and diminish toughness.
Manganese Content: Ranging approximately from 0.29-1.06%, manganese is instrumental in refining grain size and fortifying ferrite, thereby boosting tensile and compressive strength.
Silicon Content: Kept consistently around 0.10%, silicon plays a critical role in deoxidation and purification processes of molten steel, enhancing overall integrity.
Tensile strength and yield strength: For Grade A, tensile strength is no less than 330MPa, with a yield strength minimum of 207MPa; Grade B boasts 415MPa and 240MPa respectively; while Grade C impresses with 485MPa and 275MPa.
Elongation Rate: Typically exceeding 30%, this ensures the steel pipe can absorb energy through deformation upon impact, thereby preventing brittle fractures and enhancing structural resilience.
