Jim: A specific example (from my personal experience) would be a tempering process (time/temperature dependent) for strip steel which needs to meet specific physical parameters (yield strength and % elongation). When I was involved in the project, we were able to find only one manufacturer who could meet our requirements, and they spent quite a bit of time (and money) in developing their process.
Good day @Jim Wynne ;
@Ron Rompen gave a good example. My personal experiences are similar, with thermal processing (austenitizing time/temp, etc...) And many of the organizations I have worked with (aluminum casting, "BOP shop chemistry" [steel mills], , etc...)
