I'm looking for an authentic source for the mechanical properties of S41600 Cond T , I couldn't find them in ASME B&PVC Section II d , and in ASTM A582 either . Where else can I get this information ?
It won't be in the Code because it isn't an approved material.
The tensile properties should be just lime 410 as long as the C is the same.
You do need to know the exact C levels.
There are mill data sheets that have data for various tempers.
