The properties of steel can be improved in terms of fatigue, weldability, hardness, wear and corrosion resistance, ductility, and tensile strength by either alloy addition or heat treatment processes.

Steel has been used by humanity for thousands of years. Iron production can be traced back to Anatolia in about 2000 BC, with the iron age well-established by 1000 BC. By 500 BC, iron technology had ...

"Essentials of Heat Treatment" provides a through introduction to steel heat treatment, including a discussion of how heat and carbon content impact a steel's microstructure. This class also describes ...
