Are cold rolled stainless steel sheets and stainless steel strips the same?
The width of stainless steel strip is generally not more than 500mm, which can be used to process into small diameter stainless steel welded steel pipe;
The width of cold-rolled stainless steel plate is relatively large, and it is generally processed into medium and large diameter stainless steel welded steel pipes. In order to ensure that the mechanical properties such as yield strength, tensile strength, elongation and hardness of various cold-rolled stainless steel sheets meet the requirements, cold-rolled stainless steel sheets must be subjected to heat treatment such as annealing, solution treatment, and aging treatment before delivery.
The corrosion resistance of cold-rolled stainless steel mainly depends on its alloy composition (chromium, nickel, titanium, silicon, aluminum, etc.) and the internal structure of cold-rolled stainless steel, and the main role is chromium. 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. Cold-rolled stainless steel sheets are widely used in chemical, food, pharmaceutical, paper, petroleum, atomic energy and other industries, as well as various parts and components of construction, kitchen utensils, tableware, vehicles, and household appliances...
