Allowable stress values for materials used in ASME design are found in which code part?

Allowable stress values for materials used in ASME design are found in which code part?

• A. Section VIII Div 1
• B. Section II Part D
• C. Section III
• D. Section II Part A

Answer: (B)

Allowable stress values are the stress limits assigned to materials at different temperatures for design purposes. In the ASME Code, those design stress limits (the S-values) are published in Section II Part D, which is the Properties of Materials part. It provides the temperature-dependent allowable stresses for each material used in design calculations. Section II Part A contains general material property data, but not the specific allowable stress limits used for design. Section VIII Division 1 is the pressure vessel construction code that uses the allowable stresses in its rules, but does not host the primary tables themselves. Section III covers nuclear-related materials with its own data, separate from the general design code. Hence the correct source for allowable stress values is Section II Part D.
