Rolling is a technology where metals or alloys are rolled, it is put through a series of heavy rollers. Using this process, the thickness of the material is reduced and gets a definitive shape. So rolling steel enables sheet metal steel to be produced for a variety of industrial purposes, like rolling shapes for standard structural sections or special custom profiles.
Cold rolling technology refers to a process where stainless steel metals are rolled at room temperature rather than being heated to 1100 degrees Celsius. Stainless Steel Cold Rolled Sheet is rolled at room temperature by passing it through rollers which enables shaping. The steel or stainless steel must be passed through the rollers several times to obtain the level of thickness or shape required for the application. It takes longer than the hot rolling process but cold rolling is one of the best technologies for making high-end products.
Highlighting Properties Of Cold Rolling Technology:
* Smoother finish
* Metal hardness is increased
* Increased strength of up to 20 percent
* Reduces grain size of the metal
* Higher quality finish
* Higher precision than hot rolled products
* Smaller production batches
* Efficient manufacturing process
Applications of cold rolled sheets:
Cold rolled sheets are used in a varied range of applications, they have smooth surface which is applicable in varied needs. The increased yield of the material is an additional advantage which has standard austenitic stainless steels like 304L and 316L. They are used for applications like refrigerator, power distributing boards and drums, automobile roof and panels, fenders and roof panels.
The weldability like spot, projection, butt and fusion and brazeability of the stainless steel sheet is excellent. The Stainless Steel Cold Rolled Sheet as a standard grade is used in many common, low-stress applications. It has a very good surface finish that is far superior to hot rolled stainless steel sheet. The applications for this sheet includes extruded, cold headed, cold upset, and cold pressed parts and forms.
