Cold Working Sheet Metal

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 sheet metal.

The three series are 3xxx 4xxx and 5xxx. Touching a hot piece of sheet metal can burn an employee s hands or body of course sheet metal is equally conductive to cold temperatures as it is for heat. The haynes and hastelloy alloys can be readily formed into various configurations by cold working. 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.

The force exerted by rollers on the sheet reduces its thickness and increase the strength of the sheet. Cold working refers to the process of strengthening metal by changing its shape without the use of heat. Such processes are contrasted with hot working techniques like hot rolling forging welding etc. Subjecting the metal to this mechanical stress causes a permanent change to the metal s crystalline structure causing an increase in strength.

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. Metal is said to be cold worked if it is mechanically processed below the recrystallization temperature of the metal. 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. Hot working usually results in the refinement of grain structure whereas cold working merely distorts the grains and does little towards reducing its size.

Be it manual or powered equipment we have the solutions you need. Most of cold working processes are performed at room temperature. Cold rolling is often used commercially in order to produce sheet metal plates and bars. When a metal is cold rolled it is plastically deformed as it is forced between the two rolls.
