Heat Treatment of Steel 1 INTRODUCTION Heat treatment is the operation of heating and cooling a metal in its solid state to change its physical properties. An important factor is the time the cooling takes. According to the technique used, steel can be made hard to resist cutting action and abrasion, or it can be softened to permit further machining. Further, internal stresses may be removed, grain size reduced, toughness increased or a hard surface produced on a ductile interior. Alloyed steels owe their properties to the presence of one or more elements other than carbon, so I will discuss mainly the techniques of heat treatment of ordinary comercial steels. 2 IMPORTANT WORDS Ferrite pure iron (e.g. no carbon is present), the shape of the crystal and the ammount of iron atoms that form ...
