In order to accomplish this, it is often necessary to reduce the cross section of a cast structure to one-eighth or even less of its original. The major forming processes are carried out hot, at about 1,200° C (2,200° F), because of steels low resistance to plastic deformation at this temperature.Why are aluminum alloys forged at Normal Forging temperatures?The five most significant reasons are: They are very ductile at normal forging temperatures They can be forged in steel dies that are heated to the same temperature as the workpiece They do not develop scale during heating They require low forging pressures They may be forged at high or low strain ratesSee all results for this questionWhen to use hot forming or warm forming aluminum?Either warm forming (less than 482 degrees F) or hot forming (about 887 degrees Fthe alloys solvus temperature) can be used. After hot forming, an artificial aging heat treatment is required to achieve a T6 temper, which is lost during the process. A few Tier 1 suppliers already practice ET forming of aluminum alloys.See all results for this question

Hot forming and heat treatment of duplex stainless steels
working temperature drops too low. Most producers recommend a maximum hot forming temperature between 1100°C (2000°F) and 1150°C (2100°F). This upper temperature limit is suggested because of the effect of high temperatures on the dimensional stability of a part and the increased tendency to scale formation with increasing temperature. At high temperatures,Hot Forming of High Strength Aluminum Alloy Sheet a8high temperature alloy steel FormingAluminum sheet metal alloys are prime candidates for use in the automotive industry because of their good strength and stiffness-to-weight ratios. The drawback to their widespread use is their room temperature formability. Aluminum alloys possess only moderate formability at room temperature.
