S7 Tool Steel Rockwell Hardness Chart S7 tool steel is usually supplied in the annealed condition at about 187-223 HB. After hardening and tempering, the common working hardness is about 54-58 HRC. For many shock-loaded tools such as punches, chisels, shear blades, and cold-forming tools, 56-58 HRC is often the practical center because it keeps
