Answer 1

I worked as a trad blacksmith in uk for 30 years, one problem was that cheaper imported ‘mild’ steel would often not be “mild’ at all, but would harden when cooled, which caused big problems as for example, when the ‘hapenny snub’ end of a sroll would fracture and fly off as you worked the other end — as a result of adding one too many mercadees to the furness in mauritania or wherever it was made
