A basic stainless steel has a 'ferritic'structureand is magnetic. However, the most commonstainlesssteels are 'austenitic' - these have a higherchromium content andnickel is also added. It is the nickel whichmodifies the physicalstructure of the steel and makesitnon-magnetic.
Besides, which types of stainless steel are magnetic?
There are several different types ofstainlesssteels. The two main types areaustenitic andferritic, each of which exhibits a differentatomic arrangement.Due to this difference, ferritic stainlesssteels aregenerally magnetic while austeniticstainless steelsusually are not.
Also question is, will stainless steel stick to a magnet?
Steel is a metal that magnets sticktobecause iron can be found inside steel. That iswhyyou will find that while some types ofstainlesssteels are magnetic, other stainlesssteel typeswill not make magnets stick tothem.
All stainless steel is magnetic exceptausteniticstainless steel which is actually 300seriesstainless such as 304 and 316. However, 300seriesstainless is non-magnetic only after it is freshlyformed.304 is almost for sure to become magnetic after coldworksuch as pressing, blasting, cutting, etc.
