What is Stainless Steel Coil?

Stainless Steel Coils are one of the most sought after types of raw material in the construction and manufacturing industries. Thanks to their distinct mechanical and physical properties, stainless steel coils have been widely used in the production of kitchen appliances to industrial equipment. They are strong, resist corrosion, are light in weight and require low maintenance. Also, they are flexible and easily meet the requirements of a range of design criteria. Within the industry (especially manufacturing), numerous grades of stainless steel coils can be found, each with different properties and usability.

Stainless steel coil is manufactured by hot rolling stainless steel slabs in a reheat furnace. The hot rolling process is carried out at a certain high temperature. This temperature is known as the recrystallization temperature in the industry, which is between 1,100° C to 1,300° C, which often depends on the grade of the steel used for the manufacturing process. The steel slabs are continuously run through heating and rolling mills. The resultant product is then suitably coiled. Post hot rolling and coiling, the stainless steel coils are passed through the annealing and pickling lines to get softer and brighter surface finish, free of any oxide layers and impurities.

Stainless steel coils are divided into austenite, ferrite, martensite, dual-phase (ferrite-austenite) stainless steel cold-rolled coils and stainless steel hot-rolled coils.

The production process of stainless steel coil

The production process of stainless steel coil is as follows
Raw material preparation - annealing pickling - (intermediate grinding) - rolling - intermediate annealing - pickling - rolling - annealing - pickling - leveling (finished product grinding and polishing) - cutting packaging storage.
