Re: Johnny are you thinking of 18-8 ?
Johnny,
As best as I can remember the 18-8 stainless was the original steel alloy with true stainless character.
18% nickle therefor it is non magnetic. And still most frequently used for cooking pots and pans because of its ductility and ease of rolling and roller spinning.
.08% chrome, this is the culprit that causes the spalling and seizing characteristic. The chrome crystals form in the slip planes and lock the molecular structure, sort of keying the molecular slip planes. When machined these chrome crystals cut into the adjoining molecular surfaces sliding past, like a small cutting tool and the chips start the spalling.
Hope I have remembered correctly,
I've just been had by the "LHJ" ** and I'm still a bit gun shy. ** = "Luger Hoax Joker" or "something like that".
