I remember I read some 12 years ago:
GOGAN, Art. Fighting Iron. A metals Handbook for Arms Collectors. Lincoln 1999, Andrew Mowbray. ISBN 0 917218 86 8.
SMITH, Cyril Stanley. A History of Metallography: The Development of Ideas on the Structure of Metals before 1890. Cambridge/ London 1988, The MIT Press. ISBN 0 262 69120 5.
And there was no cast steel used in weaponry before middle XVIIIth century. Cast iron was used in guns and cannonballs, but it was unreliable in this task until 1620s, and not used in swords. Too brittle.
Are you sure the piece is cast and not just carved and welded?
Now, my memory is worse by the day, so I could be remembering corrupted data.
I got myself entangled in a Victorian cast iron rapier hilt not long ago...
