Hot Rolled and Cold Rolled stainless steel coils and sheets are available in different sizes in 200, 300, 400 and duplex stainless steel series.
Hot Rolled Stainless Steel Coils production starts with cast/ ground slabs being first heated and soaked in reheating furnace, they are rolled to intermediate thickness in the roughing mill, and then to the final thickness in the tandem mill. Hot Strip Mill is also equipped with online surface inspection machine for detection of surface flaws during hot rolling of strips.
Hot rolled coils are annealed and pickled in continuous annealing-pickling lines having scale breaker, shot blasting unit, sulphuric acid, and mixed acid bath. HRAP coils have a cleaner surface and have improved mechanical properties for downstream processing. HRAP line is also equipped with online reduction for providing product in 2E finish.
Cold Rolled Stainless Steel is produced by cold rolling which is the process of strengthening steel by changing its shape without using heat. During the cold rolling process, when the metal is put under mechanical stress, it causes a permanent change to the crystalline structure of the metal. This causes an increase in its strength and often improves corrosion resistance. Along with improving its surface finish, another advantage of cold rolling is better dimensional accuracy.
