Cold Rolled Stainless Steel Sheets: Pros & Cons

Cold Rolled Stainless Steel Sheets are stainless steel sheets produced using cold rolling technology, with a thickness of no more than 3mm considered thin sheets and a thickness greater than 3mm considered thick sheets. In this post, we let’s take a close look at the pros and cons of cold-rolled stainless steel sheets.

Grades of Cold Rolled Stainless Steel Sheets:

Cold-rolled stainless steel sheets refer to the cold-rolled steel sheets of grades such as 304/316L/310S, which are produced through cold rolling. Cold rolling is a process that further reduces the thickness of No.1 stainless steel plate to the desired thickness at room temperature. Compared with hot-rolled steel sheets, cold-rolled steel sheets have a more precise thickness, smooth and beautiful surface, as well as various excellent mechanical properties, especially in terms of processing performance. 

Since the original coils of cold rolling are relatively brittle and not suitable for processing, it is usually required to undergo annealing, pickling, and surface smoothing before being handed over to customers. The maximum thickness of cold rolling is 6.0MM or less, and the width is determined by the equipment capacity and market demand of each factory.

Applications of Cold Rolled Stainless Steel Sheets

Cold-rolled stainless steel sheets are stainless steel sheets produced using cold rolling technology, with a thickness of no more than 3mm considered as thin sheets and a thickness greater than 3mm considered as thick sheets. They are used for the production of corrosion-resistant components, pipelines, containers, medical equipment, and ship equipment in the petroleum and chemical industries.

Characteristics of Cold Rolled Stainless Steel Sheets:

1. Cold-rolled stainless steel sheets have high dimensional accuracy, reaching ±0.01mm.
2. Cold-rolled stainless steel sheets have excellent surface quality and good brightness.
3. Cold-rolled stainless steel sheets have strong corrosion resistance, high tensile strength, and fatigue strength.
4. Cold-rolled stainless steel sheets have stable chemical composition, pure steel quality, and low inclusion content.

Pros & Cons of Cold Rolled Stainless Steel Sheets:

Cold Rolled Stainless Steel Sheets are processed and rolled based on hot-rolled stainless steel sheets and coil. Generally speaking, the processing process is hot rolling → pickling → cold rolling. Although the steel sheet will be heated during the rolling process, it is still called cold rolling. Due to the continuous cold deformation of hot-rolled steel, its mechanical properties are relatively poor and the hardness is too high. It must be annealed to recover its mechanical properties, and the one without annealing is called “hard-rolled coil”. The hard-rolled coil is generally used to make products that do not require bending and stretching.

Pros:

1. Fast forming speed and high yield without damaging the coating.
2. Good plastic deformation ability and high yield point.
3. Stainless steel cold-rolled products have no oxide layer on the surface, good quality, and high dimensional accuracy.

Cons:

1. The wall thickness of cold-rolled stainless steel is small, and its ability to bear local concentrated loads is weak.
2. After forming, there are still residual stresses inside the section, which makes the flexural performance of cold-rolled stainless steel worse.
3. It has low toughness and is prone to torsional buckling when being bent, and prone to flexural buckling when being compressed. Its torsional resistance is poor, and the price is high.
