Why Your Silverware Rusts 27
Judebert writes: "Watching your stainless steel silverware rust is enough to drive a geek to apoplexy. Not that you care, just that it is stainless, after all. Well, some clever Brits at the Imperial College of Science, Technology and Medicine have figured out Why Stainless Steel Corrodes and published a like-named article in Nature. Science Daily, as usual, mirrored their press release.
When stainless steel goes, the results can be catastrophic. Especially considering that the stuff is used in Formula 1 engines, industrial equipment, and thousands of other places. Turns out the problem is sulfur in the steel / chromium alloy. But they've also figured out ways to fix the problem without resorting to very expensive low-sulphur steels."

For example, if you have a chunk of carbon steel, and you want to cut a shape into it with an abrasive, it is probably going to lose it's temper due to the heat (temper like is defined at the bottom of this page, not like angry) Don Fogg Custom knives [dfoggknives.com]
Stainless steel has a much higher resistance to the loss of temper due to the heat generated in it's grinding or machining. Stainless is also much less likely to have carbon burn off when under high heat.
However, Stainless in it's many forms requires a much more tightly controlled Quenching and heat treating process in order to maximize it's properties.
Stainless is good for dishwashers. Not for knives. and especially not for swords.
