A stainless steel cold-rolled coil is a flat-rolled product made from stainless steel that has undergone a cold-rolling process. This process involves passing hot-rolled stainless steel through a series of rollers at room temperature, reducing its thickness and improving its surface finish, flatness, and mechanical properties.
Stainless steel hot-rolled coils are made from stainless steel alloys, primarily composed of iron, chromium, and other elements like nickel, molybdenum, and sometimes copper.
WUXI KONGZO STEEL is a leading stainless steel coil supplier, offering the best price and service. We can process orders to any specification, length, and thickness, and then do quality inspection and packaging.

3）Piping and Tubing: Used for manufacturing stainless steel pipes and tubing in various sizes and thicknesses for applications like plumbing, industrial piping, and fluid transport.
4）Pressure Vessels: Hot-rolled stainless steel coils can be used in the fabrication of pressure vessels for applications in the chemical, petrochemical, and oil and gas industries.
5）Railway and Transportation: Employed in the manufacturing of railway tracks, shipping containers, and transportation equipment.
6）Heavy Machinery: Used in the construction of heavy machinery and equipment where strength and durability are essential.
The manufacturing process of stainless steel and alloys involves multiple steps to transform raw materials into flat, rectangular sheets or plates made of stainless steel and alloys. Here are a few key steps for stainless steel and alloys:
Molten stainless steel and alloys are cast into large ingots or billets through a casting process.
During the hot rolling process, the thickness of the steel ingot is gradually reduced and elongated to form long strips or coils.
Annealing involves heating stainless steel and alloys to a specific temperature and then slowly cooling it.
Cold rolling is carried out through rolling mills to reduce thickness to meet customer specifications.
