I have not struck MP35N afaik before, and interesting to see its use in commercial settings, and even available as bolts and nuts. Certainly not fun to machine [1]
It's hard to know just how much stronger this new processing of the alloy is than other common high strength alloys, as they list compressive yield and not tensile yield strength ... that's if the person writing didn't get the two terms confused.
As a note, I use duckduckgo and smirked somewhat at its search assist results for the few efforts to find the compressive yield of Bisalloy 400 (something I've had to drill) - checking out the listed sources it was clear it had mistakenly used the tensile yield ...
As an illustration for the differences, I found a page [2] for 4140 alloy and similar yield strengths. 4140 is reasonably workable, drilling isn't the greatest amount of effort either before it's tempered and annealed.
