korean steel specs ?

[SPEAR34]

I need to find UK / European equiv of some Korean specs namely SM45C , SS400 , CAC403 , SMC440, C1100 & FCD60

All as I know is they are machine structural steels.

I've googled to the max but its mostly in Korean.

 

[Flesh]

SM45C = AISI 1045 or DIN 1.0503
SS400 = ASTM A283 or ISO 630(80)
FCD60 = Cast Ductile Iron BS 2789, 600/3

...is what I could find.
