The 2000°F austenitize in combination with cryo and a 400°F temper led to a good combination of hardness (61-62 Rc) and toughness along with low retained austenite. Flag grind. Still in the range of xhp, elmax,3v? M390 tested higher in toughness than S45VN; however, with its quite high carbide volume I have a hard time believing that it has higher toughness in actual practice. However, nitrogen can also be intentionally added to the steel for higher amounts. This is expected due to ThermoCalc being an equilibrium calculation (infinite hold time). But there are going to still be much better steels for the job in regards to folding knifes. Spyderco. I have Cru wear, 4v, m4, and Rex45 folders as well. To test the toughness of S45VN I did three different heat treatments, all of which utilized liquid nitrogen after the quench. The same study found values for 61 Rc S30V at 149% and 61.5 Rc M390 at 179% , which are similar to those given by Crucible (though for 20CV rather than M390). My recommended heat treatment for S45VN is 2000°F austenitize along with a fast quench and a cold treatment followed by a 300-400°F temper depending on desired hardness.
