Stainless steel alone. Stainless steel, due to its superior corrosion resistance relative to most other metals, including steel and aluminum, becomes the cathode accelerating the corrosion of the anodic metal. An example is the corrosion of aluminum rivets fastening stainless steel sheets in contact with water. At elevated temperatures all metals react with hot gases. The most common high temperature gaseous mixture is air, and oxygen is the most reactive component of air. Carbon steel is limited to ~ in air. Chromium in stainless steel reacts with oxygen to form a chromium oxide scale which reduces oxygen diffusion into the material. The
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
