Manufacturing is High Tech: Annealing Steel Using Bismuth

Samuel Strapping Systems, at their Heath plant, uses a unique-to-North-America process of bismuth metal to anneal the steel used in some of their steel strapping.

The "bis" in Pepto-Bismol is bismuth.  In its metal form, bismuth is used in cosmetics.

Compared to lead, the more commonly-used agent for annealing steel, bismuth is pretty tame.

That's why it's pretty high tech to think of using bismuth metal in an annealing process to strengthen steel instead of nasty stuff like lead.  That's why a normally low-tech, in terms of how its thought of, product like steel strapping is actually pretty high-tech in the end.

Pretty cool.    And one more example of how manufacturing is high tech.
