There are several families of stainless steels with different physical properties. Basic stainless steel has a 'ferritic' structure and is therfore magnetic. These are formed from the addition of >10.5% chromium and can be hardened through the addition of carbon making them 'martensitic' and are often used in cutlery etc.

However, the most common stainless steels are 'austenitic' - these have a higher chromium content and nickel is also added. It is the nickel which modifies the physical structure of the steel and makes it non-magnetic.

Good information. I guess I'll put a regular stainless bolt and one of the new ones in a vise and give them a strength test.

No wonder you crash so much. All this stuff going through your head ('austenitic' indeed).....

I have absolutely no what idea when it comes to nuts and bolts! . All I know is it's "left to loosen" however that's not always the rule when you ride Monts and at the bolt shop I always ask for "high tensile" so's I look as though i know what I'm talking about.
Stainless are the shiny ones right?

Thanks for that Montynut. I always thought it was the chrome that did in the ferous properties of iron

Yes Ross indeed it is 'austenitic' sometimes also known as 'gamma'.

I assume you carry a big shifter (left handed naturally) while you buy bolts to support your "high tensile" line of convicing them that you are a Bolt Guru  . I'm not a bolt expert. You know what they say about experts 'X' is an unknown quantity and 'pert' is a drip under pressure

I didn't crash last weekend I did blow the crap out of an engine instead but I did not crash
