Stainless steel cleaning with H2O2

Dear Sir.
We're preparing for cleaning one Plate Heat Exchanger Unit with NaOH, Sulfamic acid 10% and Hydrogen peroxide liquid 15%. The material of plates is SUS316.

But we're not sure that Hydrogen peroxide liquid 15% should not harm the SUS316.
We intend soaking the Hydrogen peroxide liquid 15% in the Plate Heat Exchanger Unit for 14-16 hour.

Please send us some recommendation.

Thank you very much.
