Stainless steel coil

Stainless steel coils into austenitic, ferritic, martensitic, duplex (ferritic - austenitic) stainless steel cold rolled and hot rolled stainless steel coil. Stainless Steel: or call tape, coils, coil width is called more, the hardness of the strip, there are many, ranging from tens to hundreds, Customers buy easy to determine what needs to hardness. . (8K mirror luminosity) web width uncertain, there are: 30mm.60mm.45mm.80mm.100mm.200mm etc. also sub-section according to customer requirements from a metallographic point of view, because the stainless steel contains chromium leaving the surface is. chromium thin film, the membrane separating oxygen from inside the steel corrosion invasive role. In order to ensure the yield strength of various types of stainless steel coil, the mechanical properties of tensile strength, elongation and hardness to meet the requirements, you must go through annealing, solution heat treatment, aging heat treatment before delivery, stainless steel coil. The corrosion resistance of stainless steel coil depends on its organizational structure alloy composition (chromium, nickel, titanium, silicon, aluminum, etc.) and stainless steel coil inside, play a major role in 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. Stainless steel coil is widely used in chemical, food, pharmaceutical, paper, oil, nuclear and other industries, as well as construction, kitchen utensils, cutlery, vehicles, household appliances all kinds of parts.
