Hydrogen Peroxide Material

You probably could, I would check with supplier of H₂O₂ e.g. Interox. But likely to be more expensive than SS316L.

Explanation of Footnotes
1. Satisfactory to 72°F (22° C)
2. Satisfactory to 120°F (48° C)

Ratings -- Chemical Effect
A = Excellent.
B = Good -- Minor Effect, slight corrosion
or discoloration.
C = Fair -- Moderate Effect, not recommended
for continuous use. Softening, loss of strength,
swelling may occur.
D = Severe Effect, not recommended for ANY use.
N/A = Information Not Available.

Check for decomposition in presence of trace metals before changing the containers etc.

H2O2 can violently decompose in presence of trace metals such as transition metals, Manganese etc.

I worked on a water treatment job some years ago and if I remember right the spec said SS tanks had to be polished internally.

Also if ball valves are used they must have a hole drilled through the ball so there is no trapped volume of liquid. Otherwise this could decompose and liberate oxygen, causing high pressure.

You can use Alloy 20 but the corrosion rate depends on the H2O2 conc and operating temperature, i've found data on Alloy 20 and at 100% conc the max corrosion rate is < 20 mpy. (NACE CORSUR)

here you have some good info on materials compatibility with H2O2:
