luuc Posted March 24, 2008 Share Posted March 24, 2008 Hello, When you bend a stainless bar, is it correct that at the point where it is bended, it ís a little magnetic? Is it the quality of the bar? I hope you can help me, Luuc. Quote Link to comment Share on other sites More sharing options...
Autolupus Posted March 24, 2008 Share Posted March 24, 2008 The work hardening and heat affect the crystalline structure of the stainless altering it's properties. Effectively changing the metal at the bend from an austenitic stainless to a martensitic stainless, thereby becoming magnetic. http://en.wikipedia.org/wiki/Stainless_steel http://en.wikipedia.org/wiki/Austenite http://en.wikipedia.org/wiki/Martensite Quote Link to comment Share on other sites More sharing options...

David_wigren Posted March 24, 2008 Share Posted March 24, 2008 I'd noticed this too. And clearly there is something going on with the steel structure. I've also reasoned that it might be a part of why stainless gets harder the further you bend it. That together with the big apex curve on stainless is probably why it get so hard.
