Maximum Gasket Seating Stress for RTJ

I am doing bolt tensioning and torquing. As per ASME minimum gasket seating stress are given. To limit the bolt tension we need to have maximum allowable gasket seating stress value for RTJ to avoid gasket / ring failure.

Can anyone suggest what would be the maximum allowable gasket seating stress for RTJ joint having octagonal ring material of "Stainless Steel Soft Iron BHN 50 "?
