Ah, I sit corrected, thanks for the references

It's mostly for free-machining production-type steels, used in conjunction
with phosphorus and/or calcium. Those alloys are not of much interest for
small-shop work, except for the ones that are also leaded.

The non-leaded free-machining alloys have been common in production since,
roughly, the mid-'70s.
