Top of Flare Boom/Stack Material Selection
(OP)
Hello,
I am wanting to determine if 316 stainless would be suitable for some load bearing components we would supply to the top of an offshore flare stack (>1m from the tip). Historically my company has employed a 'belts & braces' approach in selecting Alloy 800H. The main rational being the combined heat (~600°C), the salt-laden environment and the flare gases (I believe H2S is a typical concern in this type of service?).
Are there any studies/literature that show 316 would be suitable in this application, ideally including estimated corrosion rates per year?

As long as there is no place that is intermittent wet/dry that is 316 you might get away with it. It sounds like a foolish way to trim a couple percent from the cost.

When you go to lower Ni than that you really start loosing resistance to high temp.
