Chloride ions are found in many places, such as salt, sweat, sea water, sea wind, soil, and so on. In the presence of chloride ions, stainless steel corrodes quickly, even more than ordinary mild steel. Chloride ions form a complex with Fe in the alloying element, which reduces the positive potential of Fe, and then is oxidized by oxidizing agents who take away electrons [1]. So there are requirements for the use of stainless steel environment, and the need to wipe often, remove dust, keep clean and dry.

316 and 317 stainless steels are molybdenum-containing stainless steels. The molybdenum content of 317 stainless steel is slightly higher than 316 stainless steel. Because 316 stainless steel contains molybdenum, the overall performance of the steel is better than 310 and 304 stainless steel, under high temperature conditions, when the concentration of sulfuric acid is lower than 15% and higher than 85%, 316 stainless steel has a wide range of uses. 316 stainless steel also has good resistance to chloride corrosion, so it is commonly used in Marine environments.

Properties of stainless steel plate
The stainless steel plate has similar resistance to general corrosion as the unstable nichcr 304. Prolonged heating in the chrome-carbide degree temperature range may affect alloys 321 and 347 in harsh corrosive media. It is mainly used in high temperature applications, where the material is required to have strong sensitization resistance to prevent intergranular corrosion at lower temperatures.

Carbon steel pipe preparation method
The raw material of carbon steel tube is round tube billet, round tube embryo to be cut by cutting machine processing billet with growth of about 1 meter, and sent to the furnace by conveyor belt heating. The billet is fed into a furnace and heated to about 1200 degrees Celsius. The fuel is hydrogen or acetylene. The temperature control in the furnace is the key problem. After the round tube billet comes out, it is perforated by the pressure punch. Generally, the most common perforator is the conical roll perforator.
