Re: Coinplate - a new, ultra durable Seed Phrase Backup solution
I just wanted to know if the Stainless Steel used for this ....also get what we call "white rust" in our country? Here is a article explaining this :
https://www.metalsupermarkets.com/what-is-white-rust/ ....because the small dent might "fade" if other corrosion takes place on the surface of the plates.
I live in a area where there are a real problem with rust... and I cannot use any product that will be influenced by rust and corrosion for something that holds very sensitive data.
Hi there, https://www.metalsupermarkets.com/what-is-white-rust/ ....because the small dent might "fade" if other corrosion takes place on the surface of the plates.
I live in a area where there are a real problem with rust... and I cannot use any product that will be influenced by rust and corrosion for something that holds very sensitive data.
I've checked the article you mentioned and it seems that this applies mostly to regular, carbon steel that is zinc coated. My understanding of this "white rust" is that it eats up a zinc coating. Since Stainless Steel we use is "naked" and has no coating, because it is naturally rust-free, this will be no concern.
You can check the previous post where I linked up to a third-party stress test. It was submerged in 16% muriatic/hydrochloric acid and the product survived it well. Our own tests also show that it holds very well against corrosion. Getting into details, AISI304 steel can get some surface level, minor rusting in sea salt environments after years of use but even there it will not make your seed unreadable. Everything is engraved quite deep and punch marks are also deep enough.
Furthermore, the design holds your seed inside a tight stainless steel sandwich which limits contact with any corrosive agent whatsoever. In the test I mentioned earlier, the acid was applied on an open device and even in that scenario, it survived well.
