"Seez Proof Steel"
(OP)
We have an old drawing that calls out "seez proof steel" for the material. Has anyone ever heard of it? A search only turns up hits for Never Seez.

RE: "Seez Proof Steel"
So I would recommend checking with whoever wants you to use this material, and ask for clarification. If it is a stainless steel they want, I'd suggest something like Nitronic 60 or Gall-Tough. If it's a P/M product, perhaps something is available in a controlled porosity, oil-bearing grade.
Good luck!
RE: "Seez Proof Steel"
How old is "an old drawing"? In the early 80's a product called "stress-proof" steel bar was introduced into the marketplace. This is a free-machining steel with a hardness around 25 HRC. The hardness is obtained by controlled temperatures in the final rolling processes and controlled cooling from rolling temperatures.
This product is sometimes offered as an alternative to heat treated (quenched and tempered) material, but because it is not quenched and tempered and the free-machining additives, it's toughness and ductility properties are not very good.
