New lightweight material is stronger than steel
Just a heads up - strength is not a single metric. There is tensile (pulling), compression, and shear (sliding) strength. There's also Young's modulus (how much something stretches), fatigue limits (steel can work perpetually with deformations under a certain threshold).There's also specific strength (strength per kg) vs strength per volume and strength per dollar.Steel also comes in lots of different flavors, with very different (orders of magnitude) strengths.
