Yes, CPM materials are great substrates for PVD coatings due to their higher tempering temperatures, uniform microstructure, and good stability after heat treatment. Our CPM steels are multiple tempered at 1000 F or higher and most PVD coatings like TiN, TiCN, TiAlN, etc. are applied around approximately 950 F. In doing so, the PVD coating process will not reduce the hardness. Grades like A2, D2, or S7 generally are not PVD coated since they have lower tempering temperatures and will lose hardness after coating.
