Common sense description of stainless steel coil surface

After N0.1 hot rolling, it is heat treated and pickled.
2B is cold rolled and then heat treated, pickled or the like, and finally flattened to obtain the proper gloss.
2D cold rolling followed by heat treatment, pickling or similar treatment or a matte surface.
HL Abrasives of appropriate particle size are polished to a continuous grained surface.
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 be subjected to heat treatment such as annealing, solution treatment, and aging treatment before delivery. The corrosion resistance of the stainless steel coil mainly depends on its alloy composition (chromium, nickel, titanium, silicon, aluminum, etc.) and the internal structure of the stainless steel coil, and the main role is the chromium element. 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 being oxidized, and increase the corrosion resistance of the steel plate. After the passivation film is destroyed, the corrosion resistance decreases.
