316l stainless steel coil is a steel coil made of stainless steel, which has good corrosion resistance, processing performance and weldability, and is suitable for a variety of media. The 316l stainless steel coil has improved corrosion resistance to reducing salts due to the addition of Mo. It is resistant to marine and industrial atmospheric corrosion and can be used in seawater equipment. 316l stainless steel coil has excellent resistance to intergranular corrosion due to its low carbon content; it can be used in pulp and paper machinery.
In order to ensure that the mechanical properties such as yield strength, tensile strength, elongation and hardness of 316l stainless steel coil meet the requirements, 316l stainless steel coil must undergo annealing, solution treatment, aging treatment and other heat treatment before delivery. The corrosion resistance of 316l stainless steel coil mainly depends on its alloy composition (chromium, nickel, titanium, silicon, aluminum, etc.) and the internal structure of 316l stainless steel coil, and the main role is chromium. Chromium has high chemical stability, can form a passivation film on the surface of steel, 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.
