8 inch carbon steel pipe Mechanical Properties
General Mechanical Properties for ASTM A106 Grade B Carbon Steel Pipe (3/4 inch):
Tensile Strength:
Minimum: 60,000 psi (415 MPa)
Yield Strength:
Minimum: 35,000 psi (240 MPa)
Elongation:
Minimum: 20% in 2 inches (for smaller diameters, such as 8 inch, the elongation requirement may be adjusted slightly).
Hardness:
Not specifically defined in the standard, but generally, carbon steel of this grade has a Brinell Hardness (HBW) of around 120-180.
Impact Resistance:
Typically measured by Charpy V-Notch test for applications requiring toughness, especially at lower temperatures. For ASTM A106, impact testing may be required if used in low-temperature environments, though it’s not a general requirement for standard applications.
Modulus of Elasticity:
Approximate: 29,000,000 psi (200 GPa)
