(OP)
Is there any rules/experience for lubrication or not when using stainless bolts and nuts, below 200°C.

I like synthetics with molydisulfide.

Not in nuclear facilities.

In the UK I think the term was anti galling compound.
I've never found a hard and fast rule for when it's needed, so if someone has one I'd be interested too.
I do know I saw it more often used on larger threads.

One word of caution since these materials come in convenient aerosol cans that make application very easy. If you have a lot of hot steam or process lines where one could sit a can on I would limit the materials to the brush top cans. Don't ask me how I know this as I stand here in my copper colored shirt.

First off I would recalculate the flange and gasket using A193 B8 Class II bolting instead of the current 316L you are now using. The added strength of the class II fastener coupled with proper tightening will give the better gasket seating stress. I would also take a good look at the gasket selection, both type and material, as you may have a problem with gasket relaxation in time. Depending on the flange design you may also have to go to an energised gasket to handle the cyclic load if the flange will not allow adequate seating stress for the existing gasket.
Here is a BN based lubricant as mention in the post by btrueblood

Isopropyl Alcohol in a standard microwave oven can be extremely hazardous to one's health.

IPA doesn't even get warm, not enough water in it. The BN forms a floculent that will stay suspended.

I've got to ask - you go to the drug store and buy a box and mix it with water? Or do you use it as it comes?
from one who has never used the stuff
-I've also heard that a little Milk of Magnesia in a lead-acid battery will bring it back to life.
Sounds like wonderful stuff!

RE: Lubrication of stainless bolts
Did you mean that you never used the stuff as a SS lubricant or never used the stuff personally? I can't remember what it was that Mom used to dose us with Milk of Magnesia for but I've used plenty of the stuff-just never as a SS lubricant.

Some of the flavors will have a small amount of chlorides to enhance the flavor.
