What I *don't* remember is what the UK calls hot rolled steel.

Aint that HRS? Or is it to simple? :-)

What we have (better use commonly) here (Germany) for free cutting is:
9SMn28k and that would translate to 1.0715
The leaded equivalent would be:
9SMnPb28 (or 11SMnPB30) translates to 1.0718

But to my knowledge, you only get round stock in free machining.


What you call drill rod, is a bit better than what we call (in Germany)
"siver steel", the quality of the Brits silver steel is unknown to me,
but I guess it is either yours, ours, inbetween, or even worse:-)). The
code for the Kraut-silver-steel is 1.2210 (or 115CrV3). A tool steel for
_cold_ work.

The stuff you get here (easily, as always) as CRS*) is
1.0036/1.0037/1.0038 AKA S235JR/S235JRG1/S235JRG2.

Somehow, I _hate_ the naming system. But what I hate most, is that they
seem to change it every 10 years. This (S235JR etc. kind) is the third
system for me.

*)
I know, CRS (or HRS) has _very_ little to do with the quality, but it
has got a common meaning for a distinct alloy.
