superior mechanical properties (1.5-2 times of top Columbus and Reynolds steels) + save a few onces of paint = light steel frame.
I thought it was relatively soft(?) nmDougSloan

Try a Google Search for Columbus Metax. Apparently it wasn't too popular (not sure why) and last I heard Columbus stopped producing it...

Check it out...

inferior mechanical propertiesContinental

Common Stainless steels + sweat + stress from riding = stress corrosion cracking = cracks in frame. Common Stainless steels are brittle and prone to cracking, especially with chlorides from sweat. Specialty stainless steels are expensive, may require specialized welding procedures,and may still have worse, or at least different, mechancial properties so that frame builders would not have the knowledge to use them.
Less than half the tensile strength and equal weight of steelMR_GRUMPY

The only plus is that it is a little harder than normal steel, and it doesn't rust as quick. Think of it this way. Would anyone use Titanium if it weighed as much as steel ??????
One good use for stainless is for lugs.

bicycles several years ago (as a feasability study)...an aquaintance of mine wound up with one. I'm not sure about the metalurgy of this particular bike, but it is beautiful, light, and rides like a dream. Interloc found it too expensive to bring into production.

IRD is one of my team's sponsors and I've seen the frames in person. VERY nice. there was even one for sale on EBAY about a month back.
