Can A2- 70 nuts be used with Inconel 601 Stud bolts if so what is the recommended torque settings (At present we are using between 50 NM and 60 NM. Additionally can 8.8 grade bolts be substituted with A4 80 Stainless Steel bolts

See: /hex_bolt_identification.htm /ansi_hardware_menu.shtml /strength_specifications_steel_bo.htm /thread_strength/thread_classes.htm /fastener_thread_stress_area.htm /calculators/torque_calc.htm /calculators/machine-design/bolt-preload/bolt-preload-calculation.htm /fastener_thread_menu.shtml /mechanics_material_menu.shtml and /galvanic_capatability.htm First, verify the application and environment requirements. Second, investigate the strength of each material by reference chart or specification Third, verify galvanic corrosion capatability Forth, Calculate desired torque based on size of the lowest strength material used in the combination and verify stress and strain are ok. Don't forget the part being clamped together or touched by the fasteners for corrosion, etc.. Now you know how to fish... Modified by Kelly Bramble at Thu, Oct 04, 2007, 08:34:29
