Hot forming

Hot forming describes all of the shaping steps that involve temperatures above the recrystallization level of a metal. The strain-hardening which occurs during reshaping is resolved by the recovery and softening processes that take place during and after the reshaping stage. This allows for extensive levels of reshaping, although the dimensional tolerance and surface quality are not as good as with cold forming. For this reason, cutting processes (turning) are often used afterwards.

This process is used for things like attachment elements of 20 mm diameter and upwards.
