Stainless steel film of chromium oxide by reaction with the oxygen in air and even the small amount of dissolved oxygen in water. This passive film prevents further corrosion by blocking oxygen diffusion to the steel surface and thus prevents corrosion from spreading into the bulk of the metal. This film is self-repairing if it is scratched or temporarily disturbed by an upset condition in the environment that exceeds the inherent corrosion resistance of that grade. However, stainless steels may suffer uniform corrosion when exposed to acidic or basic solutions. Whether a stainless steel corrodes depends on the kind and concentration of
Corrugated stainless steel tubing Corrugated stainless steel tubing Corrugated stainless steel tubing (CSST) is tubing made of stainless steel with corrugation on the inside or outside. One type is stainless steel tubing be formed with corrugated shape on outside surface. Make it higher efficiency of heat transfer, can be used to connect the form of tube soft and flexible, with good defensive displacement and vibration and noise reduction, mainly used on heat ex-changers. The other type is a type of conduit used for fuel gas distribution in buildings. It has a flexible corrugated stainless steel inner layer and an outer yellow or black plastic
