In order to carry out heat or cold processing easily and economically to form various components of an engineering structure, low-profile gold high-strength steel must have appropriate formability. Like carbon structural steels, low-alloy high-strength steels are generally capable of such processing, as well as shearing, punching, and machining processes. Although their yield points are high, they can be used for carbon even if the forming operation is severely deformed. Cold-formed presses, drawing machines, presses and other equipment formed from structural steel, but some equipment needs to be modified.
There is an inherent difference between the cold formability of low alloy high strength steel and carbon structural steel. First, the low-alloy high-strength steel produces a certain amount of permanent deformation that requires more force than a carbon structural steel of the same size. Second, when low-alloy high-strength steel is formed, a slightly larger allowable amount should be given for the rebound.
As a rule of thumb, unless a low-alloy high-strength steel is subjected to the treatment of controlling the shape of the inclusions, a larger bending radius than the carbon structural steel must be used in the cold forming.
