Piping standards typically recommend that the code stress should be less than the allowable stress. This is a safety criterion, but not a guarantee that the material will not fail. For temperatures below the ambient temperature, B31.3 includes a supplementary safety check that involves the property Minimum Design Metal Temperature (MDMT).

Most B31.3 materials in the software provide MDMT, as defined by Minimum Temperature Curve (A-D) and shown in the following Material Database Editor examples.
