Nitric acid/hydrogen peroxide
Nitric acid/hydrogen peroxide
(OP)
Does anyone have experience of or could point me to a reference on the corrosion of austenitic stainless steel (304L and 316L) in 40% nitric acid/30%hydrogen peroxide mixture at 50 deg C? My instinct is that, as these are both oxidisers , the stainless steel would be OK but I'd would prefer to see a definitive reference if one's available.

While 304 should hold up fine I have some concerns, specifically about the welds.
Any residual delta ferrite in the welds will be attacked fast.
You might consider using overalloyed filler, such as 310 to minimize ferrite in the welds.
You will need to watch out for the rick of hot tearing.
Is there any risk of chlorides in this system? Even in the low ppm levels 304 and 316 would be at risk.

Not sure what adding hydrogen peroxide does to the corrosion properties.
