Stainless steel designations C-22, C-42, C-59

[ponchoak]

I work for a small-ish boutique steel supplier. With (3) grades of stainless, including a brand new lean duplex, we thought we had a good presence in the pulp and paper industry, until recently when my boss attended a pulp and paper industry conference. He then brought home many incoherent notes and a head full of ideas.
Under strict instructions to learn more about C-22, C-42, and C-59, I set out in earnest to do some research.

I cannot find these stainless steel designations anywhere. It is his understanding that these are superb materials, it is my current belief that he needs a hearing aid. Please advise.

It took me three seconds to find Hastalloy C22

Here is the data sheet on the C-22 alloy. Your other numbers, C-42 or C-59, don't hit the windmills.

Come back with a little more information if you can.

While this designated a59, the alloy is in the C family.
