In order to ensure that the mechanical properties of all kinds of stainless steel coil yield strength, tensile strength, elongation and hardness meet the requirements, stainless steel coil delivery must be annealing, solution treatment, aging treatment and other heat treatment. The corrosion resistance of stainless steel coil mainly depends on its alloy composition (chromium, nickel, titanium, silicon, aluminum, etc.) and the internal structure of stainless steel coil, which plays the main role of chromium. Chromium has high chemical stability, can form a passivation film on the surface of the steel, isolate the metal from the outside world, protect the steel plate from oxidation, and increase the corrosion resistance of the steel plate. After the passivation film is destroyed, the corrosion resistance decreases.

Stainless steel coil is widely used in chemical, food, medicine, paper, petroleum, atomic energy and other industries, as well as construction, kitchenware, tableware, vehicles, household appliances and various parts
