Can anyone please tell me what machinable pre-hard steel has the
highest compressive yield strength ? I'm guessing it would be a pre-
hard 4000 series, perhaps 4340 or a bearing steel or pre-hard tool
I'm looking for the highest yield strength I can find in a steel that
is still machinable, i.e., not so hard that it can't really be
machined effectively. Depending on how the part is machined, I would
need a thickness of around 1.338" or 1.585".
