One Angry Soldier

I know I'm 9 years late but here's what I can tell you. I build nuclear submarines and work with this steel all the time. What the numbers represent is tensile strength. HY-80 is incredibly strong. HY-80 is meant to hold up to 80,000 psi (pulling on it), before breaking and HY-100 can hold up to 100,000 psi. Normally, with blade making this may not be the right type of steel, unless you want to use it for tug of war. I'm no blacksmith, so I could be wrong; The thinner you make it (especially using a forge) you could potentially change the integrity of it, and it may actually be far less superior as a blade, than traditional crucible steel, because it's more pure and has less carbon already. Even though it has enough to be somewhat flexible, it needs to be able to withstand a direct torpedo impact, etc. I work with it enough to understand it but am no expert, so like I said... I could be wrong. Others may have already addressed this but I didn't read the comments, so I may have repeated some things.
