I've been tasked with the job of finding hardness values for a bunch of different materials but im not sure which ASTM book has hardness values for different materials(mostly steel). Also what is the industry standard for Hardness values (Rockwell B, Rockwell C, Vickers, Brinell, Knoop).
Im assuming it depends on the company's preferred testing method.
Any light you could shed on this would be greatly appreciated
