Hydrogen Peroxide (50%) and 316L
Hydrogen Peroxide (50%) and 316L
(OP)
Hello all,
I would like to know if any one here has experience with Hydrogen Peroxide (50%) and SA 240-316L.
From what I read, it has excellent compatibility but only up to 48°C.
I would like to know what can be the result of using Hydrogen Peroxide (50%) in 316L vessel at Temp. of 55°C.
Any help will by good.
Thanks,

I don't see this as worrying.

btrueblood,
What does the decomposition rate means?
What test will you recommend to do in order to test the steel?
RE: Hydrogen Peroxide (50%) and 316L
It happens thermally and is also catalyzed by surfaces including the surface of 316/L.
The material is at no risk of corrosion BY the peroxide. But you would do well to pickle the surface to remove residual iron, as iron is definitely a catalyst for the decomposition of peroxide.

"What test will you recommend to do in order to test the steel?"
There are lab-level tests to measure the evolution of O2 gas with the sample material immersed in the fluid that is going to decompose. In the rocket biz, we used to do this with hydrazine, a similar chemical. The test is potentially dangerous - as the peroxide begins to decompose, it releases heat, which can bootstrap to a thermal runaway condition (think rocket engine); the water boils to steam and whoosh (or bang, if you don't give it a way to vent).
I'm sure this type of testing has been done by others, but I couldn't find any easy links to good data. A few hours in an engineering library would probably find some.

I see no risk with the alloy.
Handling the evolved oxygen will be your biggest issue.
And if there are any non-metals in the system they will require very very careful selection.
