304 cold rolled stainless steel coil china
N0.1 after hot rolling after heat treatment and pickling treatment. 2 b heat treatment after cold rolling, pickling or similar process, appropriate gloss finally formed. Wtri heat treatment after cold rolling, pickling or similar process or matte surface. 3#100~200# abrasive belt grinding out of products. 4#150~180# abrasive belt grinding out of products. HL appropriate granularity of abrasive polishing, so that the surface is continuous grinding grain. In order to ensure all kinds of stainless steel plate bending yield strength, tensile strength, elongation and hardness, mechanical properties meet the requirements, stainless steel coils annealing, solution that must pass before delivery, aging, heat treatment. Corrosion resistance of stainless steel plate depends primarily on its alloying constituents ( chromium, nickel, titanium, Silicon, aluminum, etc ) and stainless steel plate internal organizational structure, play a major function of chromium is an element. Chromium has a high chemical stability, steel passivation film formed on the surface, metal isolated from the outside world, and protect the steel from oxidation, increase the corrosion resistance of steel plate. Passive film damage, corrosion resistance of dropped. Stainless steel coils are widely used in chemical, food, pharmaceutical, paper, petroleum, nuclear power and other industrial and construction, household appliances, kitchen utensils, tableware, vehicle parts
