However, here's a good article that should serve the purpose. It's

background. Hint: Manganese is the big player. But for old alloys,

nickel

might be the alloying ingredient that you'd want to put in play in a
historical story:

Happy writing.


Thanks, glad you dropped by. I've gotten some very good leads, almost
all directing me to key-to-steel. I think I've got it now. My hardest
problem became finding a mix for a good basic steel, so I could
determine what the changes were.

I forget the period you're writing about, but I seem to recall it was
something from perhaps a century ago. Alloys were simpler in those days.
Most steels were plain-carbon (as they are today, actually), and the
multi-component alloys were just getting started. Stainless steel hadn't
been discovered yet.

There probably is some historical account available somewhere that tells us
*when* it was recognized that adding nickel, and then manganese, made steel
more resistant to brittle fracture at low temperatures. But as a non-fiction
writer myself, my feeling is that anyone who might know about that, when
most of the fairly knowledgeable ones here don't, is a reader so rare that
you really don't have to worry about him. g

Good luck in your quest.

I'm writing a fantasy, set in a culture that has voluntarily ended
technological life, but is discovering some of the shortfalls to that
stance. What I wanted to avoid was suggesting sulphur would increase
resistance to brittle fracture.

Or, in my case, my 'expert' character had suggesting using *less*
manganese, when he should have suggested using more. And I had no idea
at all that nickel had such a profound impact on low temp brittle fracture.

At any rate, I think I can now safely have him utter a one sentence
mixing instruction without going diametrically off target.
