D2 tool steel is a high-carbon, high-chromium, air-hardening steel. Its hardness is affected by chemical composition, heat treatment parameters, and microstructural interactions. Here are the detailed factors affecting D2 tool steel hardness. Alloying elements in the composition The composition of D2 steel is1 Carbon (C) Chromium (Cr) Molybdenum (Mo) Vanadium (V) Manganese (Mn) Silicon (Si) […]

Hardness is a fundamentally critical property for tool steels, directly influencing their ability to perform effectively in diverse applications ranging from cutting and forming to shaping various materials. Without adequate hardness, a tool steel cannot withstand the substantial loads imposed upon it during service. One very important use of tool steel is for cutting or
