Different bolt (material) at two ends of valve

Dear Experts

I am facing one problem with the Bolt at two ends of Valve. That Valve is connected with SS flange at one end and CS flange at other. While extracting Isometric, Only one end having bolts and other doesn't.

Please suggest what to do in this case.

Thanks in advance.
