are your house door keys magnetic?

[Focus Owner]

yes or no
by magnetic i mean attracted by magnets

 

[Lupi]

Have you been bored and been playing with magnets?

 

[jug]

yes or no
by magnetic i mean attracted by magnets

so you mean are they made from a ferrous material.
thats very different to magnetic.

(i am aware there are non-ferrous matrerials that are attracted to magnetic fields, but they are not used to make keys)

 

[PNL]

I'm not telling you Daz your not burgling my house :nerner:

 

[Focus Owner]

i know i should have used full scientific terms but I'm on strike today )
also the key could be stainless steel still has iron in it "ferrous"

i dnt know whether to be impressed or disgusted with your knowledge sometimes

i reckon u use wikipedia an awful lot:chin:

if not then your are prob the best pub quiz candidate ever

i know. the fact that any1 can edit/add info to it makes it ********

there are several types of stainless steel, ferritic stainless steel is attracted to a magentic field, but not all types of stainless steel are.

 

[Captain Mike]

may i ask why you want to know this info?

 

[Focus Owner]

cause its interesting
also if you are to be doing a surface grinding on stainless steel you might want to think again on using a magnetic bed
all im saying is that info could be usefull

 

[Stu DemonD]

I may add a 5th option

 

[Captain Mike]

I may add a 5th option

can we add...

"i dnt have a F*cking clue i just use my keys to open locks like a normal person?"

There are 4 types of stainless steel commercially available. Ferritic and Martensitic stainless is magnetic, Austenitic is non magnetic and Duplex might be dependent on its make up. Austenitic is used where stray magnetism may be a problem ie. motors generators etc. Ferritic is resistant to corrosion and used for components in agressive conditions ie. seawater chemicals etc. Martensitic steels respond well to hardening processes and are used mainly for surgical impliments and for load bearing purposes and Duplex grades share the properties of Ferritic and Martensitic steels.
