Stainless Steel Surface Finish
Stainless steel rolling mills reduce coils to various thicknesses and widths. Once you arrive at the desired thickness the coil is then slit-to-width through a process known as steel coil slitting.
Steel coil slitting is a metal cutting process where large rolls or coils of sheet metal are cut using very sharp rotary blades. To achieve straight lines, they are cut length-wise into the large coil, creating narrower strips. Circular blades are responsible for making the cuts as the coil runs through the slitter. These are known as “knives” and can be moved to provide for varying widths.
Stainless steel can be slit into many different widths. Every application requires its own stainless steel coil slitting capability. Stainless steel slitting proficiencies mean that all materials sent in to slit are done so according to the exact qualifications that are necessary for that particular job.
A slitting machine has three main parts: an uncoiler, the slitter, and a recoiler. All elements must be perfectly aligned to ensure the success of the material. Factors such as knife clearance and cutter spacing must be calculated and aligned. It is critical that quality tooling and sharp knives are all in place for the job to be done correctly.
Stainless Steel Slitting involves minimum burr, minimum camber, and maximum flatness.

How Stainless Steel Coils Are Made?
Stainless steel coils are the most widely used type of metal coil in the market. They are mainly used for making pipes, tubes and sheets. These stainless steel coils are manufactured using different types of raw materials and advanced technology.
Stainless steel coils are made using several processes like hot rolling, cold rolling and extrusion. The process of making these coils depends on their thickness, diameter, length and width. The most common process used to manufacture stainless steel coils is hot rolling process. It involves melting the raw material at high temperature and then shaping it into desired forms by rolling them through a series of rollers that have varying degrees of hardness. This process results in producing large sized products with a uniform thickness, size and shape.
The second commonly used process is cold rolling process which is carried out under controlled conditions so as to maintain product quality during production stages. In this process, the material undergoes three processes namely roughing pass (first pass), semi-finishing pass (second pass) and finishing pass (third pass). This method produces products with high dimensional accuracy and good surface finish with low yield loss due to less friction during rolling process. View more about stainless steel>>
