This document discusses the material properties and composition of D2 tool steel. It provides the typical chemical composition which includes 1.40-1.60% carbon and 11-13% chromium. The mechanical properties include a yield strength of 470-1510 KSI, tensile strength of 2100-2500 MPa, and hardness of 56-60 HRC. Common uses of D2 tool steel include stamping and forming dies, punches, tools, and components for scrap choppers and tire shredders due to its high strength and hardness.
