BS 1501-151 23A Equivalent

[gthlm]

Does anyone here know the modern equivalent of this grade? Our supplier doesn't know and I've googled it to death without luck! It's for a turbine exhaust duct and the drawing is early-mid 70's.

I can find ref to obsolete BS1501-151. The grades listed are 360, 400, 430 and so on to reflect the min allowed UTS. These are all just plain low carbon steel plate.

Thanks for your reply. I got an email from a friend who found it in an old book. It seems that 23A comes from an older/original revision of 1501-151. It has a UTS of 360/400.
The data sheet I got is dated 1964.
