In our current industry, the use of a stainless steel tub seal is a lot of place, can be used to hold the wine to be used for the bucket, but also can be used for other industrial purposes. One of the materials used in stainless steel barrel is sealed corrosion resistant steel. Corrosion resistant steel refers to steel, the cost of such steel in a variety of highly corrosive media can corrosion is not low. Under normal circumstances sealed stainless steel barrel after pitting corrosion First, that in some local stainless steel corrosion can see some point. General corrosion depth this point are larger than the diameter of the surface, is a severe form of perforation. Another common kind of stainless steel corrosion is crevice corrosion, which is corrosion phenomenon in the gap at the junction or some stainless steel. Intergranular corrosion is a selective corrosion, and no fixed place and size, general corrosion of microscopic scales. Stainless steel is corrosion resistant sealed barrels can reduce corrosion in the maintenance of peace in the usual phenomenon, which we usually pay attention when cleaning stainless steel barrel, while ensuring not to touch something corrosion.
