Had to use molybdenum anti-seize this afternoon. It was mil issue and the label was in poor shape as the can is almost empty. Did note that it had a maximum temperature of 575° F. (label was deteriorated in the area and this is what I am guess was after the noted temperature) but we used similar on nuclear components on the sub at greater temperatures.

I've found them in 316 SS now, like the ones linked below. The most common couplings we use here at the SS tank manufacturing company are half couplings, with just a set of threads on the outside of the tank. You might find it interesting to know we are going to build a 60" OD by 16' long SS tank with 2 to 1 heads, for a client here shortly. The welding robot will be really slick for that tank. My friend that owns the shop is planning on building a welding robot that can weld both the heads on a tank at the same time. " I was married by a judge. I should have asked for a jury.
