You are absolutely right, just for clarity:

Chromium needs to be > 12 weight-%. If you take 18 w-% Cr and 8 w-% Ni you get an austenitic steel which is (normally) neither magnetic nor able to be hardened.

And if you add 12 w-% Cr, you remove 12 w-% Fe. So formally this is right-ish too…

Which is becoming rather untrue more and more. An good engineer in Wrocław costs about the same as in Germany. So many factories and offices there, it’s hard to find people…

Because it’s a piece of manure. Let people read it, put some comments on it.

Over here it is not forbidden, but you did not get permission to reprint it…
