also......  chain was usually made of wrought iron..    ... and this is a soft metal....   i really doubt that steel was used for this at this time..    ( big difference ) 
 
with a decent blade... you can cut into mild iron without much problem...  i've done it several times...      actually..... in the forge i have a cold cut that i use weekly to cut 1/2 mild rounds..... and rarely have to dress the edge...   
 
i realize that not everyone deals with this daily basis...  but a properly heat treated piece of steel with good edge geometry should have no problem with mild iron or wrought iron.. 
 
 
on cutting....... theres also a big difference between a chopping cut and a draw cut......  with a draw cut......distal taper has a big effect when pulling the blade through the target...   .... aswell as adding to a swords ability to resist bending in a local area
