ASME material specification
ASME material specification
(OP)
Until now, I am not understand yet, about specification of ASME material. If we see on ASME Section II, we'll find same material but they have more tensile, yield and allowable strength. Example : material SA 203 Grade F, they have Tensile strength 75 ksi and 80 ksi, Yield strength 50 ksi and 55 ksi. So if we'll use the material, which one will be used?

Look under SA 705 and you will see a better representation of this.
In terms of which numbers to use, you should note that the material properties listed are the "Possible" numbers. This are the minimum values that must be made to be certified to the grade and class specified. Depending on how confident you are in your supplier and your calculations you can chooses numbers, based on the given grade and class range, that gives you the best result.
I have always gone with the lowest yield strength and highest tensile strength for any given number. This gives me the highest allowable stress for the material.
