When I was a apprentice we had to make our scrapers from gauge plate.
For extra misery we had to cut down 50mm wide to 40mm with a blunt hacksaw whilst surrounded by machines!
We had to forge end out then harden and temper followed by honing on a powered wet oil stone.
Being a cheat I didn’t temper mine and left it dead hard to last on cast iron.
Third year we got carbide
Guage plate is D1. D2 is a different animal altogether. I use quite a bit of it, D2 that is.

Yes I think thats the case. Probably O1 but could be other grades that can be used to make a gauge (or measuring tool) and wont wear too quickly.Yep, last time I bought some O1 tool steel it was flagged as "gauge plate". I suspect is is a generic name for any accurately machined tool steel plate stock and not necessarily referring to a particular alloy.
Surgical steel is another
Did you know that over 86% of surgical instruments supplied to the NHS are made in India. No, I didn't either, bit of a shocker really.
Yes, I amended it to include Pakistan. In the Pakistani factories there are a good number of child workers.
