Will Titanium Rods Hold Up Better Then Forged Steel Or Aluminum Rods? I Have Heard That Titanium Can Be Brittle. Is That True Or Is It A Myth? What Are The Best Rods Money Can Buy?
I had a brand new set from Crower, according to one engine builder he said they transfer detonation more because of their stiffness........something like that anyway.
I'll take that million dollars, thank you. First point- it would be almost impossible to make connecting rods out of hardened steel. They are either cast iron, cast steel, or a steel forging. Crower makes excellent rods, and they use 4340 alloy. That alloy might have a yield strength of 100,000 to 110,000 psi as used in a connecting rod. Could be hardened to higher strength, but then it would be too brittle, and not tough enough. The forging alloys of titanium can be anywhere from 130,000 to 160,000 psi yield, in the "as used" condition. So the titanium is lighter, that's true. But even on an "inch for inch" basis, it is also stronger.no. ill bet a million dollars on it too. NEVER ever forget something about ti. its strong..sure.. but RELATIVELY strong..for its weight. It will never be hardened steel
