If this component is a carbon or low alloy steel shell or head, the program will compute its Minimum Design Metal Temperature (MDMT). The value to be entered in this field is the user-defined MDMT. This value is for reference only and will not be used by the program.
If this material is not a carbon steel then enter a zero (0) in this field. If a value of zero is entered, the program will not echo this value out during runtime.
