You need to do a lot more work in this regard.
However, if you choose to disregard this advice, please feel free to use 6,345 as an appropriate torque.

RE: BOLT TORQUE for UNS 8810
Been said many times in several Fora; you cannot calculate torque vs. tension in bolts. Too many unknown variables. You [someone] has to "ask the bolt" what torque is needed.
Other option is to measure bolt extension/elongation. Than CAN give you a calculated value, based on Modulus of Elasticity and loaded area of bolt.

That's what happens when you give a number. Someone will ignore all the cautions and limitations and run with it -- never checking on the validity.
