Carpenter 158 vs 9310

Can somebody tell me what the difference is between c-158 and 9310 and why 9310 isn't mil-spec? I've seen 9310 used in some bolts and wonder if it's actually inferior. Is there technical data to show that c-158 is superior?

On the other hand, Carpenter 158 steel is chosen for its toughness, shock resistance, and fatigue strength. As such, it sees use in firearm components, gears, shafts, and general machinery. What Is the Difference Between 9310 Steel and 8620 Steel? 9310 steel and 8620 steel are low-alloy steels with some key differences between them.Carpenter 158 is a case (surface) hardened steel where 8620/9310 is through hardened. Case hardening allows C-158 to be very hard on the outside to prevent wear and crack formation while the inside is softer and more flexible to prevent crack propagation and absorb shock loads. 8620/9310 being through hardened can either be softer and better at ...The heat treatment process must be more closely controlled with 9310, from what I've read. I'm pretty sure Aermet 100 is a better steel than Carpenter 158 or SAE 9310. It's also made by Carpenter Technology Corporation.

In fact, standard bolts will start to show stress cracks on the locking lugs adjacent to the extractor cut after only 3,000 rounds.8620 Steel vs 9310. At first glance, it makes sense to compare these 2 steels. They’re both low alloy steels with nickel and chromium. But the 9310 steel is much more reliably stronger, and with greater toughness as well. It offers greater tensile strength and yield strength.9310 has a better charpy rating which should help to keep the lugs from ripping off the body of the bolt. From what I understand is what is said above. 158 has to be bought in bulk to make it worth while and affordable. The 9310 is cheaper to buy in smaller quantities.
