5.2.4.1 Alloys used for Cold Forging

In every major alloy group that is used for hot forging, there are alloys suitable for cold forging. The degree of formability varies widely among material groups and among alloys in each group. In general, alloys having a tensile elongation of at least 10% or reduction in area of at least 30% can be cold worked with a reasonable level of success. The best formability is achieved when elongation is above 20% and reduction in area above 45% after cold drawing. As alloy content increases, the amount of deformation possible in a single stage is usually reduced. Some of the alloys that are currently cold forged are listed in Section 4.
