Views: 0     Author: Site Editor     Publish Time: 2023-12-12      Origin: Site

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


ASTM A106B Seamless Tube 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


ASTM A106B Seamless Tube 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 tube 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.
