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.

cold-rolled-stainless-steel-coil-420s27 use hot-rolled coils as raw materials and are rolled under recrystallization, but are generally understood to be rolling using normal-temperature rolled materials. Three to six continuous rolling mills are used as cold rolling equipment, and those delivered in coils are called cold rolled steel coils.
