Cold Working Sheet Metal

Hot working usually results in the refinement of grain structure whereas cold working merely distorts the grains and does little towards reducing its size.

Cold working sheet metal.

The process consists of a set of two or more rollers spaced closed together and the sheet or strip of metal is passed through them. Such processes are contrasted with hot working techniques like hot rolling forging welding etc. The force exerted by rollers on the sheet reduces its thickness and increase the strength of the sheet. Most of cold working processes are performed at room temperature.

Sheet metal cold working can be used to produce controlled surface finish. Subjecting the metal to this mechanical stress causes a permanent change to the metal s crystalline structure causing an increase in strength. Sheet metal machines quality fabrication equipment from a company you can trust from job shop to industrial grade fabrication shops around the world power up your sheet metal fabrication performance with coldworks equipment by fabrication solutions technologies fst. When a metal is cold rolled it is plastically deformed as it is forced between the two rolls.

Since they are generally stronger and work harden more rapidly than the austenitic stainless steels the application of greater force is normally required to achieve the same amount of cold deformation. The three series are 3xxx 4xxx and 5xxx. Like heat treatable aluminum alloys cold working aluminum alloys will be placed within certain series designations based on the type of alloying element that was added and the characteristics that the metal has. Employees handling sheet metal outdoors during the winter may experience frostbite from touching it breathing in sheet metal dusta lesser known danger of working with sheet metal is the.

Cold working refers to the process of strengthening metal by changing its shape without the use of heat. Be it manual or powered equipment we have the solutions you need. Cold rolling is often used commercially in order to produce sheet metal plates and bars. Metal is said to be cold worked if it is mechanically processed below the recrystallization temperature of the metal.
