HL is polished with abrasive material of appropriate grain size to make the surface continuously grained.

In order to ensure that the mechanical properties such as yield strength, tensile strength, elongation and hardness of various stainless steel coils meet the requirements, stainless steel coils must undergo heat treatments such as annealing, solution treatment, and aging treatment before delivery. The corrosion resistance of stainless steel coils mainly depends on its alloy composition (chromium, nickel, titanium, silicon, aluminum, etc.) and the internal structure of stainless steel coils, and the main role is chromium. Chromium has high chemical stability and can form a passivation film on the steel surface to 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 coils are widely used in chemical industry, food, medicine, papermaking, petroleum, atomic energy and other industries, as well as various parts of construction, kitchen utensils, tableware, vehicles and household appliances
