Chemical Composition Of ASTM A106B Seamless Steel Pipe

The chemical composition of ASTM A106B seamless steel pipe is specified by the ASTM A106 standard, which covers seamless carbon steel pipes for high-temperature service. ASTM A106B seamless steel pipe has good mechanical properties and is widely used in petroleum, chemical industry, and boiler industries. The composition requirements for ASTM A106B are outlined below.

Chemical Composition (Heat Analysis), %:

Carbon (C): 0.30% max

Manganese (Mn): 0.29-1.06%

Phosphorus (P): 0.035% max

Sulfur (S): 0.035% max

Silicon (Si): 0.10 min

Mechanical Properties:

Tensile Strength: 415 MPa (60,000 psi) minimum

Yield Strength: 240 MPa (35,000 psi) minimum

Elongation: 22% minimum in 2 inches, 28% minimum in 8 inches

These specifications ensure that the seamless steel pipe manufactured to the ASTM A106B standard meets the required mechanical and chemical properties for use in high-temperature applications. It is essential to refer to the latest version of the ASTM A106 standard for any updates or changes in the specifications.
