Dear all

I would like to know, can we use ASME SEC VIII DIV 2 for vessel with 500 degree cel. Design Temp? As, allowable stress for Bolting above approximate 430 degree celc. is not mentioned in SEC II-D for SEC VIII DIV-2.

Is it means that SEC VIII DIV-2 vessel can't be constructed for high temp.(above 430 degree cel.)?
furthermore, if no than why Table 5A (allowable stress for plate, forging, fitting) is given up to range 500 degree celc.

With regards
vishal Tailor
