QUICK OPENING CLOSURE ASME VIII D.1 2500#

(OP)
Hope somebody can help me to fix a problem, I got request to supply a QOC "bandlock type" size 40" to be tested at 600bar ASME VIII D.1 UG35 design and U stamped.
Every time i try to calculate it with FEM analysis show that it's impossible to stay under the ASME allowable stress (I use ASTM A105 or equivalent for HUB, DOOR and SEGMENT with allowable <136MPa), is it possible to use A694F65/70 with a different allowable strees=0.8*Yield taking in consideration that it's in needed the U stamp?

Thank you for help
