Craftsman’s Cribsheet #94

In our shops we typically process metallic materials that have been cold worked. This cold working provides advantages over the initial hot-rolled material: improved mechanical properties (increased yield to tensile strength ratio), reduced ductility (crisper chip), improved dimensional characteristics including reduced out of roundness and improved straightness. Cold worked materials are capable of changes in mechanical properties and microstructure when heated to and held at increased temperatures
