RE: high yield steel

values for heat treated steels:

D-6A 250ksi
A6, W1, O2 - all over 230 ksi
H-11 240 ksi
18-Ni Maraging/300-M  ~ 245 ksi
4340 270 ksi

There are more...see www.matweb.com

RE: high yield steel

If all you want is 230 ksi YS and a comparable hardness, most untempered med-hi C steels would suffice. Surely there must be other requirements you haven't told us about. E.g., what are you making? what size bar, do you want toughness, fatigue, what environment, is it for production, what cost, etc.?  Give us more info and we'll give you better ideas.

Incidentally a 230 ksi YS should be way over your stated 300 BHN; probably over 500 as well.
