I run a tool shop and harden all kinds of steel on a daily basis.
McMaster-Carr has a problem they won’t admit to. I just sent a piece of S7 out to a metrology shop to get tested. We only buy small amounts from McMaster and have wasted a lot of time and money on S7. No problem with 420, H13, A2.
And yes the S7 came with certs.
Trouble with S7 heat treatment, won't air harden.
