I found several videos demonstrating instant rusting using hydrogen peroxide, salt and an acid of sort, but I didn't find a video demonstrating the effect without an acid. | |

| Oct 26, 2022 at 16:19 | comment | added | TLSO | The drawing process is a colf working one, no? The question is whether the high surface area of a sieve + the presence of hydrogen peroxide (I read it interacts with rust, but I'm not sure if it's true for 304) could cause quick dissolving. | |
| Oct 26, 2022 at 15:58 | comment | added | blacksmith37 | The austenitics are not ferromagnetic when annealed ( 316 may show a trace). They become increasingly ferromagnetic as they are cold worked/strain hardened. It is very difficult for me to imagine 304 dissolving in salts at ambient temperatures. | |
| Oct 25, 2022 at 22:33 | comment | added | TLSO | I understand they are more or less salt rusting-prone, but the issue is whether the extreme rusting and dissolving demonstrated in the reviewer's images could be due to the hydrogen peroxide reacting with the rust. Because otherwise, even if the solution had several dozen % of salt, how quickly should a 304 sieve dissolve? Also regarding (para)magnetism, I did mention in a comment a couple of reviews said it was uncharacteristically magnetic, but the sieve is probably made of drawn wires and it is written this could induce paramagnetism. | |
