soft iron or iron (1 Viewer)

[kalinda]

just asking but what is the difference between a soft iron core and just regualur iron

 

[Lexicographer]

Isn't this more important in Physics? It's basically how malleable the crystal structure is relative to other samples, isn't it?

some one asked that question in chemistry last week and no one knew the answer so i was just askin of any one here did

Ok,

Soft Iron contains a low amount of carbon this leads to a grain structure of mainy ferrite grains with the occasional pearlite grain with perlite made up of sheets of ferrite and cementite.

Cementite is a very hard material making it brittle and unmalleable.

Normal iron has more carbon and hence more pearlite and therefore it is harder.

If the carbon content goes above .08% (weight), then it will form cast iron which has an cementite precipitate and becomes even harder.
