Continue readingWhat you need to know about heat treating
Engineered components – from bearings to turbine blades and everything in between – acquire much of their value and application readiness during controlled heating and cooling cycles, otherwise known as heat treating. Though practiced for millennia, the process of heat treating has only, in the last century or so, given up its secrets, making it possible for manufacturers to consistently produce steel and nonferrous metal parts with specific properties and predictable lifetime and performance ranges.
