Outrageously Funny Word Dictionary :: Prehardening

👉 Pre-hardening is a process in which steel is subjected to a temperature reduction before it is passed through a heat treatment process. During this step, the steel becomes slightly softer and more ductile, allowing it to be hardened at a later stage during a final heating or tempering process. In other words, prehardening involves reducing the initial temperature of the steel by a small amount before passing it through a heat treatment process. This can result in a higher hardness (specific heat capacity) than after

👉 Prehardening is a process used in casting and forging processes to improve the strength, hardness, and ductility of cast or forged metal. It involves adding a high temperature (around 400-500°C) at the beginning of the casting or forging process to enhance the strength and toughness of the material. This step is often performed after the initial cooling of the metal, which helps in achieving a higher melting point and reducing the risk of cracking during the casting or forging process.
