The testing of the Bohler 52100 showed lower toughness when quenched from 1450’ and 1475’ even though they both were lower in hardness. Quenched from 1500’ and 1525’ at a higher hardness also showed greater toughness.
We found something similar with 5160. I’m finding that most low alloy steels do well when quenched from 1525’, the exception is O1 and O2.

I’ve got more 52100 to try 1500f and 1525f for charpy samples. I used 1475f as that’s what worked for me with Aldo’s steel in the past, even though the steel for the samples was donated by Chuck.
