BS 3146 and equivalences

Could anybody give me a reference about BS 3146 and equivalences? I am interested specific for the BS 3146 Part 1 Cla 11. What steel will be equivalent (AISI, ASTM, AMS, etc.). Also, I have a reference for "15 ND8" treated material.

Thank you

Thank you.
Any hints about castability (investment), heat treatment?
Any cross-reference with ASTM/AMS/AISI steels?
I appreciate the help.

RE: BS 3146 and equivalences

It is an investment casting grade but I do not know of an ASTM equivalent grade.
