Not wishing to hi-jack another thread, there has been talk of "Boron" steel.
What is your understanding of this in relation to sheet steel for car manufacture??
I have machined "Tool Steels" for die`s etc and if it had a content of the said Boron, then it was so hard we could barely touch it but the tool/die would last a life time.
What percentage of Boron is used and why do they use it on car bodies?
Cheers Mart.

Good to see your curiosity hasn’t diminished in time!
Basically the car manufacturers like these Ultra High Strength Steels (UHSS) because of : High strength, low weight and workability in typical sheet steel gauges for hot and cold pressings.
When Ford owned Volvo & other brands under their Premier Automotive Group division, Ford learnt a great deal from those manufacturers who where using UHSS for improved crashworthyness and light weight in complex sections of chassIs. Think B pillar, front rails, A pillar hinges.
Here’s a good article that helps introduce why.

With the different grades and % used be prepared to go down the rabbit hole of detailed metallurgy...
