Steel is an amazing substance. It’s incredibly useful, strong and versatile; it is also highly recyclable and is an industry that is making strides in reducing is global ecological footprint. Steel is ingrained in the very history of mankind, making an appearance throughout crucial elements of our advancement as a species, good and bad, from warfare to medicine and infrastructure. The world would be very different today without it, and while everyone is familiar with its pervasive nature, here are 10 interesting facts that you probably didn’t know about steel.

This is used across many different industries due to its thermal and radiation resistant qualities.
