Difference between the Max. Allowable Stress values and Design Stress Intensities (Sm)?

[Khalid Hameed]

Refer ASME BPVC SEC II Part D, Subpart 1 Stress Tables , TABLE 1A (Max. Allowable Stress Values for ferrous materials) & Table 2A (Design Stress Intensities). I want to know the difference in results we obtained by using each of them and what is their actual difference from theoretical point of view.

Refer to Mandatory Appendix 1 and 2 of the same Section/Part for the derivation of the values.
