Ancora Imparo

Things I learned today:

(German translations)
Baustähle = Structural Steel
Hitzebeständige Stähle = Heatproof Steel
Gußeisen = Cast Iron
Messing = Brass

And the fact that antimagnetic submarine steel must be sawed with blades composed of 8% cobalt and 10% molybdenum.

It’s amazing what you can learn in this business.
