Is Stainless Steel Magnetic? | Fasteners 101

In this video, one of our resident fastener specialists discusses the magnetic properties of stainless steel. The specialist uses a magnet and different grades of stainless steel to demonstrate how some fasteners are magnetic and explains how they became magnetic in the first place.

Need some stainless steel fasteners?

Want more information on stainless steel and its various types?

Tip of the day: increase the speed at least to 1.25 : )

To be exact it’s not the crystals which are altered. The word you are looking for is lattice structure.

[ferricdecay]

helpful; a lot of convoluted explanations on the interweb.

[twbishop]

@6:45 paramagnetic is the formal term, which occurs due to unpaired electrons in the lattice structure.

So much clearer now, thank you. Is it the same for 18-8 and others?

I once thought that stainless steel was non magnetic and because my cutlery was rusting I thought that it was fake but in reality, stainless steel still does rust but is resistant to a degree, if you scour and keep it near electrolytes and bathe it for a while it will change the properties of the metal to allow rusting or pitting, also stainless steel can also be stained with rust of other metals without effecting the metal beyond the stain itself, polishing can remove this blemish.

At least this video explains the scientific portion of why it's magnetic, however even with the most powerful magnet will attract many metals including aluminium and I mean neodymium or even a electrically powered magnet that's found in industrial would pick up aluminium

do 318 SS fasteners become less corrosion resistant after they are cold worked? I mean, is it the microstructure of the SS that affords corrosion resistance or the chemical composition?

Thanks for this video. Was just wondering if the cybertruck was going to be magnetic. 30x cold rolled 3mm. So perhaps partly magnetic.

Great video, I would love to see 303 and 416 added to the mix

[ilyashakim]

How can we identify if the fastners are magnetic or non magnetic? Is there any colour code/markings on the fasteners?

Mechanical fixations for stone cladding.. Basically a sheet of steel cut and bent.. Does that change the crystalline structure of S.S 316/304 enough to make it magnetic?

The person pulling tape couldn’t wait a few minutes?

[hyperion]

Thanks a bunch! I was highly upset when my MTB, which is supposed to have a steel frame attracted magnets. I thought I was conned.

[sokolbaca]

How about stainles steel 304 sheet would they be partially magnetic? Meaning not hold the magnet?

[LionelTrains]

I have a 316 stainless steel railroad spike from Bnsf railroad it is magic but don’t rust

[paducahandlouisvillerailro]

I have a 316 stainless steel railroad spike

[Dr.Gunsmith]

Great you just proved to me my brother is wrong 😂

[anuro]

I've purchased a tool from china and since it didnt stick to my magnet bar like my other stainless steel tools do I thought I was scammed lol

This could have been a 6 word long video....
