Hi, I need to make a bunch of regular and some special AXA and BXA tool holders. I've read all the posts I could find but I'm still unsure of what steel to use.
I'll have access to a milling machine for a few more weeks at the community college where I'm taking classes.
In my area, I can get 1018 cold rolled for about 20% more than A36 hot rolled. 4140 Annealed is 2-1/2 to 3 times more expensive. I don't think I can afford it!
Initially I was going to use 1018 CRS so that squaring the bar would be easier. But I've read that if CRS is machined, it can warp due to internal stresses. So then I thought of A36 hot rolled which is more stable but more work to square.
It looks like the mechanical properties of 1018 and A36 are similar.

I'm going to be buying steel tomorrow so any answers would be appreciated.
Thanks!
