of SteelTypes of Heat Treating OperationsFive operations are detailed in this lesson as the basis of heat of theseOperations RelievingWhen a metal Is heated，expansion occurs which is more or less proportional to the temperature cooling a metal,the reverse reaction takes is, a contraction is observed．When a steel bar or plate is heated at one point more than at another，as in welding or during forging，Internal stresses are set up．During heating, expansion of the heated area cannot take place unhindered，and it tends to deform．On cooling，contraction is prevented from taking place by the unyielding cold metal surrounding the heated area．The forces attempting to contract the metal are not relieved，and when the metal is cold again，the forces remain as internal stresses．stresses also result from volume changes, which acpany metal transformations and precipitation．Internal or residual stresses are bad because they may cause warping of steel parts when they are machined．To0relieve these stresses，steel is heated to around 595C，assuming that the entirepart is heated uniformly, then cooled slowly back to room temperature．This procedure is called stress relief annealing, or merely stress of characteristics inherent in cast steel, the normalizing treatment is more frequently applied to ingots prior to working，and to steel castings and forgings prior to process of normalizing consists of heating to a temperature above the third transformation temperature and allowing the part to cool in still actual temperature required for this depends on the position of the steel,0but is usually around , the term normalize does not describe the process might be more accurately described as a homogenizing or grainrefining any piece of steel, the position is usually not uniform is, one area may have more carbon than the area adjacent to positional differences affect the way in which the steel will respond to heat it is heated to a high temperature, the carbon can readily diffuse throughout, and the result is a reasonably uniform position from one area to the steel is then more homogeneous and will respond to the heat treatment in a more uniform cold deformation, steel has a tendency to harden in deformed areas, making it more difficult to bend and liable to deforming and annealing operations are performed on most manufactured steel annealingFull annealing, where steel is heated 50 to 100C above the third transformation temperature for hypoeutectoid steels, and above the lowest transfor
