Cold Working Sheet Metal

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.

Cold working sheet metal.

Cold work is defined as the plastic deformation of a metal below its re crystallization temperature. The force exerted by rollers on the sheet reduces its thickness and increase the strength of the sheet. The steel bars we machine are typically cold drawn cold worked. Metal is said to be cold worked if it is mechanically processed below the recrystallization temperature of the metal.

Bending of sheet metal is another process for cold working which involves deforming metal over a work axis thereby creating a change in the geometry of the metal. Cold rolling is often used commercially in order to produce sheet metal plates and bars. 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. Most of cold working processes are performed at room temperature.

Be it manual or powered equipment we have the solutions you need. In cold forming metal is formed at high speed and high pressure using tool steel or carbide dies. Such processes are contrasted with hot working techniques like hot rolling forging welding etc. The cold working of the metal increases the hardness yield strength and tensile strength.

Ftis split sleeve cold expansion system is a cost effective solution to problems associated with fatigue cracks in holes in metal structures. 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. Sheet metal cold working can be used to produce controlled surface finish. When a metal is cold rolled it is plastically deformed as it is forced between the two rolls.

In the precision machining industry cold working processes can include thread rolling thread forming swaging crimping staking planishing and metal spinning. The haynes and hastelloy alloys can be readily formed into various configurations by cold working.
