Heat treatment is the process of heating and cooling metals to change their microstructure and to bring out the physical and mechanical characteristics that make metals more desirable. The temperatures metals are heated to, and the rate of cooling after heat treatment can significantly change metal's properties.What is Heat Treatment? - Can-Eng EnglishSimply stated, heat treatment is the process of using heat at various, staged levels to change the physical properties (microstructure) of a material; most often metals (i.e. steel or aluminum). Heating is carried out in large-scale, industrial furnaces (extremely different from a house-hold furnace, capable of reaching temperatures heat treatment process dh40 shipbuilding steel plate

What is the process of Heat treatment? - BBN Ship Steel
