Cold Rolling Process:
Cold Rolling
Annealing
Degreasing
Tension Levelling
Surface Finish:
Smooth and Shiny: Cold-rolled stainless steel sheets typically have a smooth, glossy surface. This is often achieved through processes like polishing or skin passing (final rolling) to create a reflective finish.
Uniform Surface: The surface is more uniform and free of scale.
Cold Rolled Stainless Steel Grades:
Cold-rolled stainless steel come in various alloy grades, each with specific properties suited for different applications. Some of the most common grades include:
304 stainless steel is an austenitic stainless steel, a multi-purpose product with good corrosion resistance, used in a variety of home appliances and industrial purposes.
