"Silver Steel" and "Tool Steel"...what's the difference?

[DMS]

In the US, the round stuff is called "drill rod", and the flat stuff is called "flat stock". The water hardening type (W1 here) is cheaper, but the other varieties machine better (such as O1, which is an oil hardening, high carbon, tool steel).

Here are spec. sheets for O1 and W1 drill rod. Going by the below posts meturgy W1 seems to be closer.http://www.speedymetals.com/informa...w.speedymetals.com/information/material9.html

Sorry Idon't no why that link did not work. But if you click on the drill rod tab then click here for material description...........This will give all data on the drill rods they sell including harding and tempering temp.

I know this thread is years old, but the link didn't work because the two url's got jammed together. As of now, the first half, https://www.speedymetals.com/information/material71.html, is still a valid page. Couldn't get the other to come up.
