Stainless steel coil surface description and Production Equipment

After heat treatment and pickling treatment after hot rolling N0.1.

2B cold rolled after heat treatment, pickling or the like, and finally, after obtaining the appropriate level of gloss.

2D heat treatment after cold rolling, pickling, or similar process or matte surface.

3 # 100 to # 200 abrasive belt grinding out product.

4 # 150 to # 180 abrasive belt grinding out product.

HL appropriate size of the abrasive polishing material, the surface of a continuous grinding grain.

In order to ensure the yield strength of stainless steel coil, the mechanical properties of tensile strength, elongation and hardness to meet the requirements, must be annealed, solution treatment, aging heat treatment before delivery of stainless steel coil. The corrosion resistance of stainless steel coil mainly depends on its alloy composition structure (chromium, nickel, titanium, silicon, aluminum, etc.) and stainless steel coil inside, play a major role is the chromium. Chromium has a high chemical stability, can form a passive film on the steel surface, the metal with the outside world to isolate and protect steel from oxidation and increase the corrosion resistance of steel. After the destruction of the passive film, corrosion resistance on the decline.
